Quality of date palm cultivars response to storage at different days intervals

Abstract

The research on "Quality of date palm cultivars response to storage at different days intervals" was carried out at Agriculture Research Station, Sarai Nawrang Lakki Marwat, Khyber Pakhtunkhwa during the year 2014. The experiment was laid out in Completely Randomized design (CRD) with two factors repeated three times. The fruits harvested from date cultivars (Khudravi, Abdullahwali, Azadi and Shakri), were kept for a period of (0, 4, 8, 12, 16 and 20 days). The storage performance of date cultivars such as weight loss (%), decaying percentage, yellow color (%), brown color (%) and black color (%) of fruits were significantly observed. Cultivar Azadi showed the lowest weight loss (6.39%), decaying (0.50%), black color (45.29%) and maximum brown color (25.39%), yellow color (25.39%), while lowest weight loss (0%), decaying (0%) on 0 days, maximum black color (100%), minimum yellow color (0%) and brown color (0%) noted on 20 days of storage. Interactive effect of cultivar Azadi and 20 days storage intervals perform better for minimum weight loss, decay percentage, yellow color, brown color and maximum black color, hence recommended for the postharvest life of date palm.

Effect of coating material (corn oil) on the storage life of persimmon fruit

“…Hydrolytic enzyme activation due to ripening increased firmness that promotes intense solubilization of pectin present in the cell wall, mainly pectin methyl esterase (PME) and polygalacuronases (PG). High esterase activities in the cell wall of persimmon kernel suggest that rapid decrease in firmness [23][24]. It might be due to in the initial stages firmness more and ripening increase with decrease the firmness of persimmon fruit if storage time increased.…”
