| 摘 要： | 采用顶芽滴液法和种子浸泡法进行悬铃木多倍体诱导,比较了不同秋水仙素浓度和不同处理时间对出苗率和变异率的影响。结果表明,0.2%秋水仙素对种子进行浸泡,染色体未出现加倍,而0.3%秋水仙素对子叶进行连续7天的处理,诱导加倍情况最好。

| Abstract: | Polyploidy induction of Plantanus acerifolia were studied by dropping apical buds of stem and soaking seeds were adopted.And the seeding rates and variance rates were compared by different concentration of colchicines solution and different treatment time.The results showed that treatment with 0.2% colchicine was no effective for soaking seeds method.But for dropping apical buds of stem with colchicines,the chromosome number of Plantanus acerifolia was all doubled.The most effective induction was 0.3% colchicines for 7 days. |
