Abstract

The study is aimed to understand effects of ethephon(lmg/1), ABA(0.lrng/l), BA(0.lmg/l). and NAA (0.lmg /1) soaking treatment on the seed germination of perennial ryegrass 'Dandy', creeping bentgrass 'Penlinks', tall fescue 'Arid' and kentucky bluegrass 'Nasaw'. These experiments are carried in vitro and their results are summarized as the followings ; In case of ethephon (lmg /1) soaking treatment of seed, the early germination of tall fescue 'Arid' and perennial ryegrass 'Dandy' was good without the soaking times. creeping bentgrass 'Penlinks' and kentucky bluegrass 'Nasaw' obtained the best results at 12 hr. soking treatment, and the longer the soaking time, the higher the germination percentage. The early germination percentage of tall fescue 'Arid' and perennial ryegrass 'Dandy' increased more highly at ABA(0. tmg /1) soaking treatment than at the control. The germination percent-age of creeping loentgrass 'Penlink' and kentucky bluegrass 'Nasaw' had respectively the best results at 6hr. and l2hr. soaking treatment. The early germination percentage of tall fescue 'Arid' and kentucky bluegrass 'Nasaw'increased more highly at BA (0.lmg /1) soaking treatment than at the control, and especially had the best results in 6hr. soaking treatment. perennial ryegrass 'Dandy' had the best results at l0min. soaking treatment, and the longer the soaking time, the lesser the germination percentage. The early germination of perennial ryegrass 'Dandy'. creeping bentgrass 'Penlinks' and tall fes- cue 'Arid' increased more highly at NAA (0.lmg /1) soaking treatment than at the control, and especially had the best results at l2hr. soaking treatment. However, the germination of Kentucky bluegrass 'Nasaw' seeds inhibited at NAA (0.lmg /1) soaking treatment. Key words: Ethephon, ABA, BA, NAA, Soaking treatment, Seed germination.
