| Abstract:
Contents of endogenous abscisic acid (ABA) and ethylene in litchi fruit during development were determined and Ag2S2O3 (STS) which inhibits synthesis of ethylene was used to study fruit maturation and coloration. The content of ABA increased rapidly a week before pericarp coloration. Change in ethylene was similar, except that there was a small climactic after ABA. With the occurrence of ethylene climactic, there was a rapid increase in sugar content and invertase activity. STS delayed fruit coloration and maturation. It was suggested that the increase in ABA might have induced the synthesis of ethylene, which consequently promoted fruit maturation and coloration. | |
