| 摘 要： | 利用秋水仙素作为诱导剂,对不同木薯品种进行多倍体诱导试验.结果表明,用4、6 g/L的秋水仙素处理木薯腋芽生长点,其诱导效果比较好.对变异枝条进行无性繁殖和染色体鉴定,结果显示变异后代在形态特征、染色体数目上都有变化,显示出了多倍体的特征.

| Abstract: | Different varieties of cassava were treated with colchicines to induce polyploidy plants. Treated with colchicines at the rate of 4 g/1 or 6 g/l, the cassava axillary bud growth point was found to have better inducing effects. The induced shoots were asexually propagated and their chromosomes were stained. They were found different from the control plants in morphology, chromosome numbers, and displayed polyploidy characteristics. |
