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
