秋水仙素处理对柴胡产量性状及细胞学形态的影响

Effect of Yield Traits and Cytological of Polyploid Breeding of Bupleurum

以柴胡种子和幼苗为试材,研究了秋水仙素处理对柴胡产量性状及细胞学形态的影响。结果表明:柴胡经秋水仙素处理产生的突变株根的长度增加39.3%;主根直径平均值重量增加也非常明显,增加幅度达到51.8%;根与对照相比明显增粗,增加幅度达到67.4%,说明柴胡多倍体诱导后产量明显上升;经秋水仙素处理的柴胡气孔明显变大,每个视野中气孔的数量明显减少,说明柴胡经秋水仙素处理后,染色体的倍数发生了加倍。

Taking the seeds and seedling of Bupleurum as test material,the yield traits and cytological of polyploid breeding of Bupleurum by colchicine treatment were studied.The results showed the upleurum by colchicine treatment produced a mutant strain of root length increased 39.3%;root mean diameter weight increased very significantly,the rate reached 51.8%;root obviously thickening compared to control,increased to 67.4%,that yield increased significantly after Bupleurum polyploid induction,the blowhole obviously bigger,the number decreased obviously in each view of the pores,it illustrated that bupleurum by colchicine treatment,chromosome doubled.
