Abstract

Abstract: Effects of exogenous GA₃(100mg/ L) treatment on changes of endogenous hormone , chlorophyll , carotenoid content in peel of citrus fruit were investigated and their possible connections with changes in color and
lustre of citrus fruit were also examined. The results showed that GA₃ treatment had little effect on ABA content , however , it inhibited decreasing of endogenous GA₃ and ZT content , correspondingly , it delayed chlorophyll degradation and inhibited orange carotenoidβ-cryptoxanthin biosynthesis and acumulation that led to repress development
color and lustre.

Key words: Citrus, GA₃, Chlorophyll, Carotenoid, Color and lustre
