Abstract
The vigour of seeds with sprouting damage stored for 8 and 20 months was examined. The vigour evaluated on the basis of germinability, length of the first leaf and length of the longest root, and electrical conductivity values of leachates, decreased simultaneously with an increase in sprouting damage. Germinability of seeds stored for 8 months ranged from 41 to 76%, while in the case of seeds stored for 20 months it dropped below 10%. The length and dry matter of the first leaf and the longest root showed a similar tendency. Electrical conductivity of leachates increased as sprouting damage and storage time increased. Coefficients of correlation between values of the vigour indices, calculated individually for every degree of sprouting damage, assumed significant and increasing values for seeds with greater sprouting damage, and for seeds with evident sprouting they ranged from -0.790** to 0.987**. For control seeds there was no significant correlation between the values of electrical conductivity and the other vigour indices.
