Abstract/Contents:"Seed vigour testing is an important component of crop seed analysis. Commonly used vigour tests were evaluated to determine their ability to assess seed quality in three perennial ryegrass (Lolium perenne L.) seed lots. Standard germination results showed no significant difference in germinability among the three seed lots. Germination percentages from the cold test were lower than those from standard germination, but no significant (p < or = to 0.05) differences were observed. However, significant differences in shoot height of seedlings following both the germination and cold tests were found. Single seed and bulk conductivity tests showed significant differences among the seed lots with the single seed conductivity test producing greater differences than germination percentage and shoot height among the seed lots. These findings indicate that commonly used vigour tests can differentiate seed quality among commercially acceptable perennial ryegrass seed lots. Seedling growth, conductivity, and accelerated aging tests were the most sensitive tests for seed vigour. Although the standard germination test is the most widely accepted measure of seed quality, these data suggest that vigour testing may be an important method for further evaluating turfgrass seed quality."
