| 摘 要： | 以^60Co不同剂量对小苍兰不同大小种球辐射处理，结果发现：随着辐射剂量增强，使小苍兰植株生长量避渐降低，花期推迟，开花率降低。红色品种的Est同工酶对辐射敏感，但黄色和紫色品种不敏感。5000R剂量可以使小苍兰产生的损伤作用在M1代表现出来。

| Abstract: | The corms of Freesia were irradiated with~(60)Co at different doses.The growth of Freesia decreased with the increase in~(60)Co irradiation dose. The esterase isozyme(Est enzyme) of the red-flower variety seemed to be sensitive to irradiation while that of the yellow-flower and purple-flower varieties was not.The effect of irradiation was expressed in the M_1s when the dose of~(60)Co irradiation was 5 000 R. |
