A special variety of R. communis selected for the present investigation, indicated two types of lipases. One of these, is active at pH 4.5 and another at pH 6.8. The acid lipase was maximum in dry seeds. The control and the irradiated seeds when germinated in dark showed a decrease in acid lipase. The decrease in acid lipase was dependent on the period of germination and the applied irradiation dose. The presence of a de novo synthesis of another activity measured at pH 6.8 was found after 24 hr of germination of the control as well as the irradiated seeds. The new activity termed as a neutral lipase showed a gradual increase with the period of germination. Irradiation played a characteristic role in the production of this activity.
