| 摘 要： | 将蚕豆种子无菌苗(对照)和离体繁殖3代无菌苗作为供试材料,观察它们在高温和紫外线胁迫下的生长和根尖细胞有丝分裂的情况。试验结果表明,供试植株在高温和紫外线胁迫下在外观上表现叶片枯黄、植株死亡,在染色体水平上发生了畸变,紫外线胁迫造成的畸变程度大于高温胁迫,3代克隆苗的畸变程度大于种子苗。

| Abstract: | Using propagated-plantlets from the 3~(rd) generation of Vicia faba as materials,the effects of heat and ultraviolet stress on growth and the mitosis of root-tip cells of plantlets were studied.The results showed that the frequency of the plantlets with yellow leaf and dead plantlets and chromosomal aberrations were increased by use of both stress compared with CK,the effects of ultraviolet stress were stronger than that of heat stress.The frequency of chromosomal aberrations of plantlets from the 3~(rd) generation was higher than that of plantlets germinated from seeds. |

| Keywords: | Vicia faba rapid propagation heat and ultraviolet stress chromosomal aberration |
