Abstract
Internal browning (IB) is one of pineapple fruits' main postharvest physiological disorders in response to cold storage. The purpose of the research was to study the response of GP3 and MD2 clones to postharvest treatment with the application of ABA, chitosan, and decrowning on the IB severity and other fruit qualities. The experimental design used a Completely Randomized Design with 3 factors of clone (GP3 and MD2), decrowning (crown and crownless), and fruit coating [chitosan 1%, ABA 50 mg/L, ABA+chitosan mix, and control (H2O)]. The fruits were kept at 7 oC and observed at 0, 3, 6, 9, 16, 23, 30, and 37 days. The results showed that the MD2 was significantly lower IB than GP3. IB severity was negatively correlated with ascorbic acid (AsA) content. MD2 had lower fruit weight loss (FWL), higher AsA, soluble solid content (SSC), and SSC/titratable acidity (STA) ratios compared to GP3. The crown+ABA treatment decreased IB severity of GP3, with an IB severity level of 0.75% after 37 days which was lower than that of crown+H2O by 9.17% and crownless+H2O by 8.42%. ABA treatment also showed higher skin dehydration and FWL and AsA, SSC, titratable acidity, and STA were not significant to the control.
