Abstract
Field experiments were carried out in the Sudety Mountains conditions at the Mountain Station Paszków belonging to Lower Silesian Centre of the Agricultural Advisory in Wrocław at an altitude of 540 m a.s.l. Pod samples were taken every week from the fodder galega field. The sampling began when 50% of pods were fully ripening (brown). A delay in sampling resulted in the decrease in seed yield but it did not affect a number of seeds per pod, weight of seeds from pods and weight of 1000 seeds. A date of sampling had no effect on the percentage of hard seeds, which ranged from 64.7% to 73.4% (without scarification). Both mechanical and chemical scarification enhanced the germination assessed after 4 and 7 days. Scanning electron microscope analysis showed that chemical scarification caused damages to seed coat, especially in the region of a micropyle, whereas mechanical scarification effected in scratching of seed coat.
