| Abstract/Contents: | The growth of the organs of etiolated seedlings of perennial ryegrass cv. S24 during endosperm-dependent growth was described. It was shown that there were 3 phases of endosperm-dependent growth during which the growth of the root (up to 3 days), then the mesocotyl and coleoptile (3-6 days after germination) and finally of the leaf, was dominant. Seedlings which developed from heavy seeds had longer and heavier leaves and roots than those from light-weight seed, but seed weight had no significant effect on mesocotyl length of etiolated seedlings or coleoptile length in illuminated seedlings. The illuminated seedlings had longer and heavier leaves and roots, and shorter coleoptiles, than the etiolated seedlings from seed of similar weight. The total weight of illuminated heavy-seed seedlings was greater than that of dark-grown seedlings and the loss of initial seed weight was lower. In a study of 5 grass species those with the largest and smallest seeds (Italian ryegrass and timothy) had the longest and shortest seedling organs, respectively. Other species studied were meadow fescue, tall fescue and perennial ryegrass. Seed weight appeared to be responsible for differences in organ length between small-seeded timothy and the other species. Differences in the comparative lengths of the organs of the other species appeared to be mainly due to genetic differences and were not associated with seed weight. |
