摘　　要：采用(６０)Ｃｏｒ射线、电子束转换的Ｘ射线，用４个辐照剂量、４个辐照时期对４个地方的大蒜品种进行抑制试验，以明确辐照的敏感期。结果发现，２种射线辐照大蒜在休眠期只需４０Ｇｙ即可抑制发芽；各品种间抑制发芽的比较敏感的临界期；江苏太仓蒜为９月１５日、河南郑州蒜和山东金乡蒜为８月２２日，江苏邳州蒜则为８月１５日。The sensitive period was determined through buds germination inhibition using^60R-ray and electron beam converted X-ray at four irradiation dosages and fourirradiation interval in four species of garlic. The results indicated that the garlicbuds germination, at dormant period by irradiation of either r-ray or X-ray at40Gy, could be inhibited, and the critical period for inhibiting buds germination were15th, Sep. for Jiangsu Taicang, 22th, Aug. for Henan Zhengzhou and ShandongJinxiang, 15th, Aug. for Jiangsu Pizhou respectively.
