Vigour Test In Oil Seed Rape And Peas
Søren Ugilt Larsen
A vigour testing experiment with spring oil seed rape (Brassica napus) and pea (Pisum sativum) was performed. The aim ofthe study was to subject seeds of the two species to "controlled deterioration" and then compare the results of a vigour test with field observations.
There is interest in examining if there is a correlation between the results of a vigour test and the field performance of the seeds to better predict seed quality. In order to test this, a vigour test was applied to a number of seed lots, and the test results were compared to results of field trials, i.e. trials where the development of plants of the different seed lots was followed during the growing season.
If the vigour test is to be considered as applicable there must be a close correlation between its results and results of the field trial, i.e. seed lots with the best test results should have the best field performance. Thus, on the basis ofthe vigour test it should
