摘要
Abstract
Seasonal changes in enzyme activities and citrate concentration during the development of citrus fruits were investigated. The result showed that the organic acid concentrations reached a peak in the 100 - 130days after anthesis and gradually declined during later stages of fruit maturation in most varieties of citrus,but declined only slightly thereafter in lemon [Citrus lin on (L.) Burm]; there is no relation between the activity of citrate synthetase(CS) and the different acid concentration in different citrus fruits; the increase of the activity of the cytosolic aconitase in the late period of the development of citrus fruits accelerated the degradation of citric acid in citrus fruits; the higher the activity of phosphoenolpyruvate carboxylase(PEPC) and the ratio of NAD-dependent isocitrate hydrogenase(PEPC/NAD-IDH- ), the more the concentrations of organic acids in citrus fruit.关键词
