| 摘 要： | 目的]建立广西常见桑树品种的多倍体诱导体系。方法]采用不同浓度秋水仙素对3个品种的桑树进行处理，研究3种品种桑树的多倍体诱导体系；并在染色体数目鉴定的基础上，对多倍体桑幼苗性状进行描述。结果]浓度0．3％的秋水仙素浓度处理效果最好。3种桑品种中，桂桑优62诱导率最高。四倍体植株的气孔大小和气孔数量均与二倍体植株有显著差异（P〈0．05），可辅助鉴定桑树倍性。结论]该方法建立了广西常见桑树品种的多倍体诱导体系，为桑树的进一步开发利用提供了依据。

| Abstract: | Objective ] To establish polyploidy induction system of common mulberry variety in Guangxi. Method ] Three kinds of mulberry were treated by different concentration of colchicine, the polyploidy induction system was studied ; on the basis of chromosome number identifi-cation, the traits of polyploidy mulberry seedlings were described. Result] 0.3% colchicine has the best effect. The induction rate of Gui-sangyou 62 is the highest. The stomatal size and stomatal number of tetraploid plants has significant difference （ P 〈 0.05 ） with diploid plants. Conclusion] Polyploidy induction system of common mulberry variety in Guangxi was established, which will provide a basis for further devel-opment and utilization of mulberry. |
