Effects of Abscisic Acid on Bioactive Compounds and Postharvest Quality of Climacteric and Non-Climacteric Fruit

Abscisic acid (ABA) is a growth regulatory substance that plays an important role in various processes the cell, such as plant adaptation to environmental threats, seed development, dormancy, budding, and fruit ripening. Another of abscisic increased antioxidant capacity, total phenol content, carotenoid, anthocyanin content. The content bioactive compounds antioxidants parameter quality can decrease due improper postharvest handling. Many treatments have been conducted maintain or delay declining fruits. This current research was done determine concentrations on papayas cucumbers' experiment arranged completely randomized design with three replications. data were expressed mean ± standard deviation analyzed using SAS (Statistical Analysis Software). Significant differences between means determined by Student's t-test, p-values less than 0.05 considered significant. Results regarding color testing, DPPH, soluble solids showed 380 µMol 100 mg/l concentration could increase (climacteric fruit) during However, applying cucumbers (non-climacteric no significant effect phenol, compared control group. results ripening climacteric fruit, ABA enhanced improved quality. not observed non-climacteric fruit.
