摘　　要：本研究以山丹新麦草为材料,通过秋水仙素处理萌动种子、胚芽、二倍体植株幼苗染色体加倍研究,探讨了不同诱变材料的适宜处理浓度和时间,从而比较出最适宜的染色体加倍方法。结果显示:最好的加倍方法是用0.1%的秋水仙素溶液处理二倍体幼苗24h诱变率最高,为62.5%。In this paper, The germinating seeds, embroy and diploid seedlings of Psathyrostachys perennis Keng. cv. shandan were treated with colchicines of different concentrations and treatment time. The results were showed that the doubling effect was best and the the induction frequency was highest 62. 5% by treating diploid seedling with 0. 1% colchicines.
