Chl a, Chl b, Chl, Car, and TA represent chlorophyll a, chlorophyll b, chlorophyll, carotenoid and total anthocyanin, respectively. Chl a/b represents the ratio between chlorophyll a and chlorophyll b. Chl/Car represents the ratio between total chlorophyll and carotenoids. All values in the table are expressed as mean ± standard error (n = 3). Different letters in the same row indicate significant differences between treatments by Duncan’s multiple range test (p ≤ 0.05).
