“…Pineapple types have different resistance to IB physiological damage. The 'MD2' pineapple cultivar is a hybrid pineapple that has relatively high resistance to IB compared to the 'Smooth Cayenne' pineapple [18]. Pineapple cultivars of 'Smooth Cayenne', 'Cayenne Lisse', 'Smooth Guatemala', 'Thypone', 'St.…”

Changes in pineapple storage temperature accelerate the increase in internal browning (IB) incidence. This study aims for postharvest applications with changes in storage temperature affecting IB incidence and severity. This research was conducted on ‘GP3’ and ‘MD2’ pineapple clones when they were ripe for export. The experimental were a completely randomized design of storage temperatures (T1: at 7°C for 30 days and T2: at 7°C for 28 days followed by 16°C for 2 days), clones (‘GP3’ and ‘MD2’), decrownings (crown and crownless), and coatings [chitosan 1%, ABA 50mg/L, ABA+chitosan mixture, and control (H2O)]. The results showed that T2 had a significant effect on the increase IB incidence in ‘MD2’ and IB severity in ‘GP3’ compared to T1. Ascorbate acid decreased in ‘MD2’ stored at T2, but had no effect on ‘GP3’. Soluble solid content (SSC) of ‘MD2’ was higher than ‘GP3’. Titratable acidity (TA), SSC/TA ratio, and mold severity were not significantly affected by treatments. The T2 had a significant effect on fruit temperature (FT), with an increase of 2.77-2.88ºC. An increase in FT was positively correlated with maturity, fruit weight loss, and skin dehydration. During the 28 to 30 days of storage, the T2 treatment increased in ripeness by 81.25%.

The shelf life of pineapple is significantly influenced by storage temperature and can be prolonged by maintaining an optimal temperature range of 5-12°C. However, there is still the problem of internal browning (IB) in the long-term storing of fresh harvest at cold temperatures. Postharvest application of 380 µM ABA (Abscisic Acid) to the crown, which is a source of ABA endogenous was found to suppress IB, while the concentration of 95 µM was not effective. Therefore, this research aimed to determine the response of GP3 and MD2 clones to postharvest treatment with the application of 50 mg/L 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 7oC and observed at 0, 3, 6, 9, 16, 23, 30, and 37 days. The results showed that MD2 was significantly lower IB than GP3 and IB severity negatively correlated with ascorbic acid (AsA) content. MD2 had lower fruit weight loss (FWL) and skin dehydration (SD), higher AsA, soluble solid content (SSC), and SSC/titratable acidity (STA) ratios compared to GP3. The crown + ABA treatment decreased the IB severity of GP3, with a level of 0.75% after 37 days which was lower than crown + H2O by 9.17% and crownless + H2O by 8.42%. ABA treatment also showed higher SD and FWL, while AsA, SSC, TA, and STA were not different from the control.
