Abstract

Initial rates of enzyme activities studied in various seed lots of sorghum showed that amylase, glutamic:pyruvic transaminase, RNase and glutamate decarboxylase followed the vigour profile i.e. an increase after 6 days of aging treatment followed by a decrease with up to 48 days of treatment. Acid phosphatase, tetrazolium reduction and 14C-leucine incorporation declined directly with aging time. These activities did not increase with aging for 6 days. Proteinase was the only enzyme that increased during accelerated aging. It was postulated that this enzyme could cause the fall in all other enzyme activites and therefore may play an important role in the loss of seed vigour. Examination of the components released from seeds into water and of the rates of their leakage, showed that the efflux was associated with severely-damaged seeds rather than with those lacking vigour
