Abstract/Contents: | "Seed weight, total germination and rate of germination varied markedly amongst 44 cultivars of Poa pratensis L. and 1 cultivar of Deschampsia caespitosa Beauv. Individual seed fresh weights ranged between 0.20 and 0.51 mg. It is suggested that these differences result from variation among cultivars rather than seed lots. Germination varied between 9-97% after 47 days, with the time to reach 50% of the total number varying between 5-14 days. No relationship between seed weight and germination or rate of germination was found. After 47 days the constant temperature (20 degrees Celsius) regime for germination was replaced with 16 hours at 20 degrees Celsius and 8 hours at 4 degrees Celsius. In response to the alternating temperatures, germination totals increased in a few cultivars, particularly `Fortuna' (Poa pratensis) and `Bar DC 980' (D. caespitosa). Is is assumed that some seed of these grasses were dormant prior to this change to alternating temperatures." |
