Seeds of two varieties of Chickpea (Cicer arietinum L.) were treated with different doses of gamma-rays. The activity of alpha-amylase was estimated separately in cotyledons and embryo-axis. The alpha-amylase activity in cotyledons of L 144 showed an increase upto 6th day and in Hima upto the 4th day of seedling growth. In the embryo-axis, the maximum enzyme activity was noted on the first day in case of L 144 and on the 4th day in case of Hima. An increase in radiation dose decreased the enzyme activity in cotyledons as well as in embryo-axis.
