Capítulo 7: Análisis de sanidad de semillas

7.1 ObjetoEl objeto de un análisis de sanidad de semillas es determi-nar el estado de sanidad de una muestra y, por inferencia, la del lote de semillas.

El análisis de sanidad de semillas es importante por cua-tro razones:a. El inóculo transmitido por las semillas puede dar lugar

a un desarrollo potencial de la enfermedad en el campo y reducir el valor comercial del cultivo.

b. Los lotes importados de semillas pueden introducir en-fermedades en nuevas regiones. Por lo tanto, los análi-sis pueden ser necesarios para cumplir con los requisi-tos de cuarentena.

c. El análisis de sanidad de semillas puede diagnosticar las causas de una germinación o implantación a campo deficientes y, por lo tanto, complementar los análisis de germinación.

d. Los resultados de los análisis de sanidad de semillas pueden indicar la necesidad de hacer el(los) tratamien-to(s) de lote(s) de semillas para erradicar los patógenos transmitidos por la semilla o para reducir el riesgo de transmisión de enfermedades.

7.2 Definiciones7.2.1 Sanidad de las semillas

La sanidad de las semillas se refiere principalmente a la presencia o ausencia de organismos que provoquen enfer-medades, tales como hongos, bacterias y virus y plagas animales incluyendo nematodos e insectos, pero también pueden estar involucradas condiciones fisiológicas como la carencia de oligoelementos.

7.2.2 Pretratamiento

Es todo tratamiento físico o químico realizado en el labo-ratorio sobre la muestra de trabajo, que precede a la incu-bación, realizado sólo para facilitar el análisis.

7.2.3 Tratamiento de semillas

Ver 2.2.12. Para el análisis de sanidad, un lote de semillas puede tratarse con el fin de controlar los patógenos de las plantas o las plagas de insectos o corregir las deficiencias de oligoelementos.

7.2.4 Programa de Validación ISTA para Métodos de Sanidad de Semillas

Antes de ser publicados en las Reglas Internacionales para Análisis de Semillas, los análisis de sanidad de semi-llas de ISTA (nuevos o equivalentes) se validan. Los prin-cipios y factores que deben considerarse en la validación de métodos para la detección de patógenos transmitidos por semillas se describen en el ISTA Technical Guidelines for Organising and Analysing Results of Proficiency Tests (PT) and Interlaboratory Tests for Validation of Methods (CT).

7.3 Principios generalesEl análisis de sanidad de semillas se debe realizar usando métodos y equipos que hayan sido probados previamente para garantizar su idoneidad. Existen diferentes métodos de análisis disponibles que varían en sensibilidad y repro-ducibilidad y en la cantidad de entrenamiento y equipo que requieren. El método usado dependerá del patógeno o de la condición a ser investigada, de la especie de semilla que se trate y del propósito del análisis. La selección del método y la evaluación de los resultados requieren conocimiento y experiencia de los métodos disponibles. Se determinan las condiciones especificadas por el remitente como presencia o ausencia de organismos que provoquen enfermedades, plagas y condiciones fisiológicas desfavorables con tanta exactitud como el método empleado lo permita.

7.4 Procedimientos7.4.1 Muestra de trabajo

Dependiendo del método de análisis, se puede usar como muestra de trabajo a toda la muestra a enviar al laborato-rio o a una parte de ella. La muestra debe ser envasada y remitida de manera que no se altere el estado de sanidad de las semillas.

Excepcionalmente se podrá requerir una muestra a enviar mayor que la especificada en 2.8 y, en tales casos, deberá informarse al respecto a quien tome las muestras. Cuando la muestra de trabajo sea una parte de la muestra a enviar, la reducción debe llevarse a cabo conforme a 2.5.2 tomando las precauciones pertinentes para evitar la conta-minación cruzada.

Normalmente, la muestra de trabajo no debe ser infe-rior a la especificada en la descripción del método.

Kapitel 7: Gesundheitsprüfung von Saatgut

7.1 GegenstandDer Gegenstand einer Prüfung der Saatgutgesundheit ist die Bestimmung des Gesundheitszustandes einer Saatgutprobe und der durch die Probe repräsentierten Saatgutpartie.

Die Gesundheitsprüfung des Saatgutes ist aus vier Grün-den bedeutsam:a. Samenbürtige Krankheitserreger können eine fort-

schreitende Krankheitsentwicklung im Feldbestand hervorrufen und den wirtschaftlichen Wert des Ertra-ges herabsetzen.

b. Durch importierte Saatgutpartien können Krankheiten in neue Regionen eingeführt werden. Untersuchungen, um den Quarantäneerfordernissen zu genügen, können dafür notwendig sein.

c. Die Prüfung der Saatgutgesundheit kann die Keim-lingsbeurteilung erleichtern und die Gründe für eine schlechte Keimung oder einen schlechten Feldaufgang aufzeigen und so die Bestimmung der Keimfähigkeit ergänzen.

d. Die Ergebnisse der Prüfung der Saatgutgesundheit können bzw. sollen auf die Notwendigkeit der Durch-führung einer Saatgutpartiebehandlung(en) weisen, um samenbürtige Pathogene zu vernichten oder das Risiko einer Krankheitsübertragung zu reduzieren.

7.2 Begriffe7.2.1 Saatgutgesundheit

Die Gesundheit des Saatgutes bezieht sich primär auf das Vorhandensein oder das Fehlen von krankheitsverur-sachenden Organismen, wie Pilze, Bakterien, Viren und tierische Schädlinge, einschließlich Nematoden und In-sekten, aber auch physiologische Schäden, wie Mangel an Spurenelementen, können einbezogen werden.

7.2.2 Vorbehandlung

Eine physikalische oder chemische Laborbehandlung der Untersuchungsprobe vor der Inkubation zur Erleichterung der Prüfung.

7.2.3 Saatgutbehandlung

Siehe 2.2.12. Für die Gesundheitsprüfung von Saatgut ist es erlaubt, dass eine Saatgutpartie zur Beherrschung von

Phytopathogenen oder Insektenbefall sowie zur Beseiti-gung von Spurenelementmangel behandelt ist.

7.2.4 ISTA-Validierungs-Programm für Methoden zur Gesundheitsprüfung von SaatgutVor der Veröffentlichung in den Internationalen Vor­schriften für die Prüfung von Saatgut werden die neuen oder äquivalenten Methoden zur Gesundheitsprüfung von Saatgut validiert. Die Prinzipien und Faktoren, die bei der Validierung von Methoden für die Bestimmung samen-bürtiger Krankheitserreger berücksichtigt werden müssen, sind im ISTA Technical Guidelines for Organising and Analysing Results of Proficiency Tests (PT) and Interlabo­ratory Tests for Validation of Methods (CT).

7.3 Allgemeine Grundsätze Die Prüfung der Saatgutgesundheit sollte unter Verwen-dung von getesteten Methoden und Ausrüstung durch-geführt werden, um abzusichern, dass sie für den Zweck geeignet sind. Verschiedene Untersuchungsmethoden sind möglich, die sich in Empfindlichkeit und Reproduzier-barkeit sowie den Anforderungen an Erfahrung und Aus-rüstung unterscheiden. Welche Methode verwendet wird, hängt vom Krankheitserreger oder den Untersuchungs-bedingungen, der Art des Saatgutes und dem Zweck der Untersuchung ab. Die Wahl der Methode und Auswertung der Ergebnisse erfordert Kenntnis und Erfahrung bezüg-lich der verfügbaren Methoden. Das Vorhandensein oder Fehlen von Krankheitsorganismen, Schädlingen und phy-siologischen Schäden, angegeben durch den Einsender, wird bestimmt, so genau wie die Methode es erlaubt.

7.4 Verfahren7.4.1 Untersuchungsprobe

Die gesamte Einsendungsprobe oder ein Teil von ihr kann je nach Untersuchungsmethode als Untersuchungs probe verwendet werden. Die Probe sollte so verpackt und ein-gereicht werden, dass sich ihr Gesundheitszustand nicht ändert.

Ausnahmsweise darf eine Einsendungsprobe, die grö-ßer als in Vorschrift 2.8 beschrieben ist, gefordert werden und in solchen Fällen muss der Probenehmer entsprechend instruiert werden.

Wird als Untersuchungsprobe nur ein Teil der Einsen-dungsprobe benötigt, muss die Teilung gemäß Vorschrift

Chapitre 7 : L’analyse sanitaire des semences

7.1 ObjetL’objet d’une analyse sanitaire de semences est de déter-miner l’état sanitaire d’un échantillon de semences, et par déduction celui du lot de semences.

Les analyses sanitaires des semences sont importantes pour quatre raisons :a. L’inoculum transmis par les semences peut provoquer

le développement progressif d’une maladie en culture et réduire la valeur marchande de la récolte.

b. Les lots de semences importés peuvent introduire des maladies dans de nouvelles régions. Les analyses pour répondre aux exigences de la quarantaine peuvent donc être nécessaires.

c. L’analyse sanitaire des semences peut élucider l’éva-luation de plantules et les causes de mauvaise germi-nation ou d’une mauvaise levée au champ et compléter ainsi l’analyse de germination.

d. Les résultats de l’analyse sanitaire des semences peuvent indiquer la nécessité de mettre en œuvre/réali-ser des traitements de lot de semences afin d’éradiquer les pathogènes transmis par les semences ou de réduire le risque de transmission de la maladie.

7.2 Définitions7.2.1 État sanitaire des semences

L’état sanitaire des semences se réfère principalement à la présence ou à l’absence des organismes provoquant des maladies, tels que les champignons, bactéries et virus, ainsi que des parasites animaux, y compris des nématodes et des insectes, mais les conditions physiologiques telles que l’insuffisance d’oligoélément peuvent être impliquées.

7.2.2 Prétraitement

Prétraitement se réfère à tout traitement physique ou chimique effectué au laboratoire sur l’échantillon de tra-vail qui précède l’incubation, réalisé uniquement pour faciliter l’essai.

7.2.3 Traitement

Voir 2.2.12. En analyse de la qualité sanitaire des se-mences, un lot de semences peut être traité dans le but de contrôler les pathogènes de plantes ou les insectes ou pour corriger les manques d’oligoéléments.

7.2.4 Programme de Validation de Méthode d’Analyse Sanitaire des Semences de l’ISTAAvant la publication dans les Règles Internationales pour les Essais de Semences, les méthodes d’analyse sanitaire de l’ISTA (nouvelles ou équivalentes) doivent être vali-dées. Les principes et les facteurs qui devraient être consi-dérés dans la validation des méthodes pour la détection des pathogènes transmis par les semences sont décrits dans le ISTA Technical Guidelines for Organising and Analysing Results of Proficiency Tests (PT) and Interlaboratory Tests for Validation of Methods (CT).

7.3 Principes générauxL’analyse sanitaire des semences devrait être réalisée en utilisant des méthodes et un équipement qui a été testé pour assurer qu’ils sont adaptés pour ce but. Différentes méthodes d’analyse sont disponibles, variant dans la sen-sibilité et la reproductibilité et au niveau de la formation et de l’équipement exigés. La méthode employée dépendra du pathogène ou de la condition à étudier, des espèces de semences, et du but de l’essai. Le choix de la méthode et l’évaluation des résultats exigent la connaissance et l’expé-rience des méthodes disponibles. La présence ou l’absence d’organismes de la maladie, de parasites et de conditions physiologiques délétères indiqués par l’expéditeur est esti-mée aussi exactement que la méthode employée le permet.

7.4 Procédures7.4.1 Échantillon de travail

L’échantillon soumis entier, ou une proportion de celui-ci, selon la méthode d’analyse, peut être employé comme échantillon de travail. L’échantillon devrait être emballé et soumis de façon à ne pas modifier l’état sanitaire des semences.

Exceptionnellement, un échantillon soumis plus grand que ce qui est prescrit en 2.8 peut être exigé et dans ce cas l’échantillonneur sera informé en conséquence.

Quand une partie de l’échantillon soumis est exigée comme échantillon de travail, la réduction sera effectuée selon 2.5.2, en prenant des précautions appropriées pour éviter la contamination croisée.

Normalement l’échantillon de travail ne sera pas infé-rieur à ce qui est indiqué dans la méthode décrite.

Des répétitions contenant un nombre indiqué de se-mences, s’il y a lieu, seront prises au hasard dans un sous-échantillon après mélange complet.

International Rules for Seed Testing

Effective 1 January 2021

Chapter 7: Seed health testing

7.1 ObjectThe object of a seed health test is to determine the health status of a seed sample, and by inference that of the seed lot.

Health testing of seed is important for four reasons:a. Seed-borne inoculum may give rise to progressive

disease development in the field and reduce the commercial value of the crop.

b. Imported seed lots may introduce diseases into new regions. Tests to meet quarantine requirements may therefore be necessary.

c. Seed health testing may elucidate seedling evaluation and causes of poor germination or field establishment and thus supplement germination testing.

d. Seed health test results can/may indicate the necessity to carry out/perform seed lot treatment(s) in order to eradicate seed-borne pathogens or to reduce the risk of disease transmission.

7.2 Definitions7.2.1 Seed health

Health of seed refers primarily to the presence or absence of disease-causing organisms, such as fungi, bacteria and viruses, and animal pests, including nematodes and insects, but physiological conditions such as trace element deficiency may be involved.

7.2.2 Pretreatment

Any physical or chemical laboratory treatment of the working sample preceding incubation, given solely to facilitate testing.

7.2.3 Seed treatment

See 2.2.12. For seed health testing, a seed lot may be treated for the purpose of controlling plant pathogens or insect pests, or correcting trace element deficiencies.

7.2.4 ISTA Seed Health Method Validation Programme

Before publication in the International Rules for Seed Testing, the ISTA seed health testing methods (new or equivalent) are validated. The principles and factors which should be considered in the validation of methods for the detection of seed-borne pathogens are described in the ISTA Technical Guidelines for Organising and Analysing Results of Proficiency Tests (PT) and Interlaboratory Tests for Validation of Methods (CT).

7.3 General principlesSeed health testing should be performed using methods and equipment which have been tested to ensure they are fit for purpose. Different methods of testing are available, varying in sensitivity and reproducibility and in the amount of training and equipment required. The method used will depend on the pathogen or condition to be investigated, the species of the seed, and the purpose of the test. Selection of the method and evaluation of the results requires knowledge and experience of the methods available. The presence or absence of disease organisms, pests and deleterious physiological conditions specified by the sender is estimated as accurately as the method used permits.

7.4 Procedures7.4.1 Working sample

The entire submitted sample, or a proportion of it, depending on the test method, may be used as a working sample. The sample should be packaged and submitted in a manner which will not alter its seed health status.

Exceptionally, a submitted sample larger than that prescribed in 2.8 may be required and in such cases the sampler must be instructed accordingly.

When a portion of the submitted sample is required as a working sample, the reduction must be carried out in accordance with 2.5.2, taking appropriate precautions to avoid cross-contamination.

Normally the working sample must not be less than that specified in the method description.

Replicates containing a specified number of seeds, if required, must be taken at random from a subsample after thorough mixing.

Reglas Internacionales para Análisis de Semillas

7-2

Si se requieren repeticiones conteniendo un número especifico de semillas, éstas deben tomarse al azar de una sub-muestra luego de mezclarlas cuidadosamente.

7.4.2 Tratamiento de semillas

Los resultados del análisis pueden estar influenciados por el tratamiento aplicado al lote de semillas. Los análisis de sanidad de semillas tratadas generalmente dan resultados poco fiables debido al enmascaramiento o inhibición del crecimiento del organismo estudiado. Las Hojas de Méto-dos Individuales determinarán si es aceptable el análisis de las semillas tratadas.

7.4.3 Almacenamiento de muestras

La microflora, en el lote de semillas o en la muestra, pue-de cambiar considerablemente durante el almacenamiento en condiciones en las que la viabilidad de las semillas se mantiene satisfactoriamente. La selección de las condicio-nes apropiadas de almacenamiento debe tener en cuenta la temperatura de almacenamiento y el recipiente óptimos con el fin de mantener la integridad de la muestra.

El desarrollo abundante de hongos saprófitos en las pruebas, incluyendo “hongos de almacenamiento”, puede ser una indicación de que la semilla no es de buena cali-dad debido a las condiciones de cosecha, procesamiento o almacenamiento desfavorables o al envejecimiento. Al-gunos hongos (como Rhizopus spp.) se diseminan rápida-mente sobre los análisis hechos en blotter y pueden pudrir plántulas inicialmente sanas o interferir en el crecimiento del patógeno de las semillas infectadas. Un pretratamien-to, como se describe en el método específico, puede ser aconsejable.

7.4.4 Instrucciones específicas

Los métodos de análisis de sanidad de semillas se publican en la red, en la página de ISTA, en:

www.seedtest.org/seedhealthmethods

Los métodos de sanidad de semillas normalmente se basan en un huésped y un patógeno, pero pueden incluir métodos de múltiples patógenos. Antes de su publicación, todos los métodos de análisis de sanidad de semillas deben validarse usando el Programa de Validación de ISTA para Métodos de Sanidad de Semillas. Los métodos validados de esta manera en el momento de la publicación, se enumeran en la Tabla 7A. Las adiciones, actualizaciones y eliminacio-nes a esta lista se pueden encontrar en la página de ISTA (www.seedtest.org/seedhealthmethods). La lista definitiva es mantenida por la Secretaría ISTA. Es responsabilidad del laboratorio que usa el método, la de consultar esta lista.

7.5 Cálculo y expresión de los resultadosLos resultados se expresan cualitativamente o cuantitati-vamente como se especifica en los métodos individuales prescriptos.

7.6 Informe de los resultadosLos resultados de un análisis de sanidad de semillas se de-ben informar en “Otras determinaciones” de la siguiente manera:• los resultados cualitativos o cuantitativos, como se

especifica en los métodos individuales;• los resultados negativos y positivos, como se especifi-

ca en los métodos individuales;• el nombre científico del patógeno detectado;• el porcentaje de las semillas infectadas;• el método utilizado, incluyendo cualquier pretrata-

miento (7.2.2);• el tamaño de la muestra o fracción analizada;• cualquier método adicional permitido que se haya

usado.

La ausencia de una declaración sobre la condición sanita-ria de las semillas no implica necesariamente que la condi-ción sea satisfactoria.

Internationale Vorschriften für die Prüfung von Saatgut

2.5.2 unter Berücksichtigung entsprechender Vorsichts-maßnahmen zur Verhinderung einer Kreuz-Kontamination erfolgen.

Normalerweise darf die Untersuchungsprobe nicht kleiner sein als in der Methodenbeschreibung vorgegeben.

Wenn Wiederholungen mit einer bestimmten Anzahl von Samen gefordert werden, sind diese aus einer gut durchmischten Teilprobe zufallsgemäß zu entnehmen.

7.4.2 Saatgutbehandlung

Die Ergebnisse können durch die Behandlung der Partie beeinflusst werden. Prüfungen der Saatgutgesundheit, die bei behandeltem Saatgut angewendet werden, ergeben ge-nerell unreellere Ergebnisse aufgrund der Hemmung oder Unterdrückung des Wachstums des Ziel-Organismus. Die jeweiligen Methodenblätter geben an, ob die Prüfung von behandeltem Saatgut zu akzeptieren ist.

7.4.3 Probenlagerung

Die Mikroflora der Samen einer Partie oder einer Probe kann sich beim Lagern unter Bedingungen, bei denen die Lebensfähigkeit der Samen ausreichend gewahrt bleibt, beträchtlich ändern. Die Wahl von entsprechenden La-gerbedingungen muss die optimale Lagerungstempera-tur und Behältnisse zur Erhaltung der Probenintegrität berücksichtigen.

Eine starke Entwicklung von saprophytischen und „Lager-Pilzen“ in Untersuchungen kann anzeigen, dass infolge ungünstiger Ernte-, Aufbereitungs- oder Lagerbe-dingungen oder der Alterung die Samen nicht von guter Qualität sind. Einige Pilze (z. B. Rhizopus spp.) breiten sich schnell bei Papiertests aus und können ursprünglich gesunde Keimlinge befallen oder auf Platten den Krank-heitserreger infizierter Samen durch Überwachsen beein-trächtigen. Eine Vorbehandlung, wie sie in der spezifi-schen Methode beschrieben wird, ist zu empfehlen.

7.4.4 Besondere Richtlinien

Die speziellen Methoden zur Gesundheitsprüfung von Saatgut werden auf der ISTA-Website publiziert, unter www.seedtest.org/seedhealthmethods.

Sie basieren normalerweise auf einem Wirt und einem Krankheitserreger, jedoch können Multi-Pathogen-Metho-den eingeschlossen sein. Vor der Veröffentlichung müssen alle Methoden zur Gesundheitsprüfung von Saatgut durch das ISTA-Validierungs-Programm für Methoden zur Ge-sundheitsprüfung von Saatgut validiert worden sein. Die bis zum Drucktermin validierten Methoden sind in Tabelle 7A aufgeführt. Ergänzungen, Aktualisierungen und Strei-chungen zu dieser Liste sind auf der ISTA-Website (www.seedtest.org/seedhealthmethods) zu finden. Die verbind-liche Liste ist im ISTA-Sekretariat erhältlich. Es liegt in der Verantwortlichkeit des Labors, das die Methode nutzt, diese Liste hinzuzuziehen.

7.5 Berechnung und Wiedergabe der ErgebnisseDie Ergebnisse werden entsprechend der jeweiligen Me-thodenvorschrift entweder qualitativ oder quantitativ angegeben.

7.6 Berichterstattung der ErgebnisseDas Ergebnis einer Gesundheitsprüfung bei Saatgut muss unter „Weitere Untersuchungsergebnisse“ wie folgt be-richtet werden:• entweder qualitative oder quantitative Ergebnisse, wie

in der einzelnen Methode spezifiziert;• negative oder positive Ergebnisse, wie in der einzelnen

Methode spezifiziert;• der wissenschaftliche Namen des nachgewiesenen

Erregers;• der Prozentanteil infizierter Samen;• die verwendete Methode einschließlich jeglicher Vor-

behandlung (7.2.2);• die Größe der untersuchten Probe oder Fraktion;• jegliche zusätzliche und zulässige Behandlung, die an-

gewendet wurde.

Das Fehlen einer Angabe zum Gesundheitszustand besagt nicht zwangsläufig, dass der Gesundheitszustand zufrie-denstellend ist.

Règles Internationales pour les Essais de Semences

7.4.2 Traitement

Les résultats d’analyse peuvent être influencés par le traite-ment appliqué au lot de semences. Les analyses sanitaires des semences sur les semences traitées fourniront généra-lement des résultats d’analyse incertains provoqués par le masquage ou l’inhibition de la croissance de l’organisme cible. Les fiches de méthode détermineront si l’analyse de semences traitées est acceptable.

7.4.3 Stockage d’échantillon

La flore microbienne des semences, dans le lot ou l’échan-tillon, peut changer considérablement pendant le stockage dans les conditions où la viabilité des semences est main-tenue d’une manière satisfaisante. Le choix des conditions de stockage appropriées doit prendre en compte la tempé-rature optimale et le contenant de stockage afin de mainte-nir l’intégrité de l’échantillon.

Le développement abondant de moisissures saprophy-tiques comprenant le « champignon de stockage » dans les analyses peut être une indication que les semences ne sont pas de bonne qualité en raison des conditions défavo-rables de récolte, de procès ou de stockage, ou du vieillis-sement. Certains champignons (tel que Rhizopus spp.) se dispersent rapidement sur le buvard et peuvent entraîner la pourriture de plantules saines à l’origine ou peuvent interférer avec la croissance du pathogène à partir des semences infectées déposées sur le buvard ou le milieu. Le prétraitement comme décrit dans la méthode spécifique peut être recommandé.

7.4.4 Consignes spécifiques

Des méthodes d’analyse sanitaire spécifiques peuvent être trouvées en ligne sur le site Internet de l’ISTA à : www.seedtest.org/seedhealthmethods.

Les méthodes d’analyse sanitaire sont normalement ba-sées sur un hôte, et un pathogène, mais les méthodes pour plusieurs pathogènes peuvent être incluses. Avant publica-tion, toutes les méthodes d’analyse sanitaire des semences doivent être validées selon le Programme de Validation de Méthode d’Analyse Sanitaire des Semences de l’ISTA. Les méthodes validées ainsi au moment de l’impression sont listées dans le Tableau 7A. Des additions, des mises à jour et des suppressions à cette liste peuvent être trou-vées en ligne sur le site Internet de l’ISTA (www.seedtest.org/seedhealthmethods). La liste définitive est tenue par le secrétariat de l’ISTA. Il est de la responsabilité du labora-toire utilisant la méthode de consulter cette liste.

7.5 Calcul et expression des résultatsLes résultats sont exprimés qualitativement ou quantita-tivement comme indiqués dans les différentes méthodes prescrites.

7.6 Indication des résultatsLes résultats d’un test d’analyses sanitaires doivent être reportés sous « Autres déterminations » selon les indica-tions suivantes :• résultats qualitatifs ou quantitatifs, comme indiqué

dans les méthodes individuelles ;• résultats négatifs ou positives, comme indiqué dans les

méthodes individuelles ;• nom scientifique tu pathogène détecté ;• pourcentage de semences contaminées ;• méthode utilisée, incluant tout prétraitement (7.2.2) ;• taille d’échantillon ou de la fraction examinée ;• toute procédure additionnelle autorisée utilisée.

L’absence d’indication sur l’état sanitaire des semences n’implique pas nécessairement que l’état sanitaire est satisfaisant.

gInternational Rules for Seed Testing

Effective 1 January 20217-2

7.4.2 Seed treatment

Test results may be influenced by treatment applied to the seed lot. Seed health tests on treated seeds will generally deliver unreliable test results caused by masking or inhibition of the growth of the target organism. Individual Method Sheets will determine whether the testing of treated seeds is acceptable.

7.4.3 Sample storage

The microflora of seed, in the lot or the sample, may change considerably during storage in conditions in which seed viability is satisfactorily maintained. The se-lection of the appropriate storage conditions must take into account the optimal storage temperature and con-tainer in order to maintain sample integrity.

Abundant development of saprophytic moulds including ‘storage fungi’ in tests can be an indication that the seed is not of good quality due to unfavourable harvesting, processing or storage conditions, or to ageing. Some fungi (such as Rhizopus spp.) spread rapidly over tests on blotters and may rot originally healthy seedlings or may interfere with outgrowth of the pathogen from the plated infected seeds. Pretreatment as described in the specific method may be advisable.

7.4.4 Specific directions

Specific seed health testing methods are published online on the ISTA web site at:

www.seedtest.org/seedhealthmethods

Seed health methods are normally based on one host, and one pathogen, but multi-pathogen methods may be

included. Before publication, all seed health test methods must be validated through the ISTA Seed Health Method Validation Programme. Methods validated in this way at the time of printing are listed in Table 7A. Additions, updates and deletions to this list can be found on the ISTA web site (www.seedtest.org/seedhealthmethods). The definitive list is held by the ISTA Secretariat. It is the responsibility of the laboratory using the method to consult this list.

7.5 Calculation and expression of resultsResults are expressed either qualitatively or quantitative-ly as specified in the individual prescribed methods.

7.6 Reporting resultsThe results of a test for seed health must be reported un-der ‘Other determinations’ as follows:• either qualitative or quantitative results, as specified

in the individual methods;• negative and positive results, as specified in the

individual methods;• the scientific name of the pathogen detected;• the percentage of infected seeds;• the method used, including any pretreatment (7.2.2);• the size of the sample or fraction examined;• any additional permitted procedure used.

The absence of a statement concerning the health condition of the seed does not necessarily imply that the health condition is satisfactory.
