Abstract: Three purple tea cultivar, Zifuxing 1, Zijuan, Hongye 1, and two green leaf cultivar Rougui and Fuding Dabaicha, as well as the albino tea cultivar, Baijiguan, were used as test materials to reveal the relationship between the accumulation of color-presenting substances and endogenous hormones in tea plants. The contents of major color-presenting substances, anthocyanin, chlorophyll, carotenoids and phytohormones (ABA, JA and SA) were determined in different tea cultivars. The results show that purple teas generally contained higher anthocyanin and ABA contents, which showed a highly significantly positive correlation. While ABA had a significantly negative correlation with chlorophyll and carotenoids. The correlation between ABA and anthocyanin changing patterns among different leaf positions of purple tea and the expression patterns of relative genes were also analyzed, which indicates that ABA might play a positive effect on anthocyanin synthesis in tea plants.
