Total phenol, flavonoid, anthoayanin and nutrient content development of water apple fruit affected by gibberellic acid

The study was carried out to investigate the pigments (chlorophyll and anthocyanin), total phenol, flavonoid and mineral (K+) content in water apple fruit affected by gibberellic acid. The lowest amount of chlorophyll was observed in the control treatment. The highest chlorophyll content was found at 60 ppm GA3. The most effective concentration to earlier maturity of water apple fruit was 60 ppm of GA3. Moreover, flavonoid content was observed higher in 60 ppm GA3 than control, 30 and 90 ppm GA3 concentration. However, the most effective concentration for flavonoid content was in the 60 ppm GA3. Fruit K+ content was significantly increased by GA3 treatments, especially at 60 ppm. Anthocyanin compounds were found increasing trend while increasing the maturity development.
