摘要
用60 Coγ射线辐照观赏荷花莲子与种藕进行诱变。结果表明 ,莲子的诱变率大于种藕。辐照莲子适宜剂量为 30～ 60Gy;红色系和复色系品种较易发生变异 ,白色系品种未发生变异 ;已选育出的 2个荷花优变系观赏价值较高。
The effects of γ-ray irradiation on seeds and stems of ornamental lotus were studied. The results show that the mutation rate of seeds is higher than that of stems, and 30～60Gy is the appropriate irradiation dose. The varieties with red or multi-color flower are more mutable than those with white flower. Two varieties were selected.
