| 摘 要： | 在室温条件下,用不同浓度（0,0.005%,0.2%,0.4%,0.8%）秋水仙素溶液分别处理露地黄瓜品种CU901干种子和萌动种子,观察秋水仙素对其生长发育的影响及其诱变效应。试验结果表明,以0.8%的秋水仙素液浸泡CU901萌动种子4h的诱变效果最好,染色体加倍率可达到7.27%。与原二倍体相比,同源四倍体的萌芽率降低,侧枝数减少,节间变短、变细,叶柄变短、变细,叶片变厚且颜色明显加深,叶面积增大,花器变大,果形指数减小,且秋水仙素浓度越高,效果越明显。四倍体花粉粒的大小不一,多数畸形,可染率显著降低。

| Abstract: | Effects of different colchicines concentration (0,0.005%,0.2%,0.4% and 0.8%) on the dry seeds and the germinating seeds of cucumber cultivar CU901 in open field were studied. The results showed that germinating seeds of CU901 with 0.8% colchicines for 4 h had the highest chromosome -doubled rates of 7.27% . Compared with diploidy plants,the germinating rate decreased,the number of lateral branches of tetraploidy plants were less,the length of leafstalk and stem were shorter and thinner,the leaves were thick... |
