摘要
本文用不同浓度秋水仙素和不同处理时间对山丹新麦草幼苗进行染色体加倍研究。结果表明:最适宜的处理浓度和时间是0.10%的秋水仙素处理24h的四倍体诱变率最高,达62.5%。
In this paper, Psathyrostachys perennis Keng. cv. shandan seedlings were treated with colchieines of differ- ent concentrations and treatment time. The results showed that the effects of the treatment with 0. 10% colchieines for 24 hours was the best and plants of the 4X Psathyrostachys perennis Keng. cv. shandan were obtained, ratio of induction was 62. 5%.
