This invention involves a method for assessing the quality of a seed lot by determining the vigor rating of a plug flat of seedlings. The vigor rating can be determined without controlling the conditions under which the seedlings are grown. The seedlings can be grown under optimum, greenhouse, commercial or outdoor growing conditions. Image analysis equipment is employed to determine the vigor rating. The image analysis equipment is used to measure the surface area of the leaves of the seedlings, calculate the standard deviation of the leaves and to calculate the germination percentage of the seedlings. The image analysis equipment can also be used to calculate the vigor rating or the vigor rating can be determined by hand via mathematical calculation.

L'invention a trait à une méthode pour évaluer la qualité de semences en déterminant l'indicateur de vigueur d'un lot de semences. L'indicateur de vigueur peut être déterminé sans contrôler les conditions dans lesquelles les semis sont cultivés. Les semis peuvent être cultivés dans des conditions optimales, en serre, en milieu commercial ou à l'extérieur. Un analyseur d'images est utilisé pour mesurer la surface des feuilles de semis, pour calculer la déviation type des feuilles et la réaction germinative des semis. L'analyseur d'images peut également être utilisé pour calculer l'indicateur de vigueur, qui peut aussi être déterminé manuellement au moyen de calculs mathématiques.
