Improving yield, quality and storability of “Samani” date palm fruits by some pre- and post-harvest treatments

الملخص EN

The aim of this investigation is to study some pre- and post-harvesting treatments affecting yield, quality and storability of “Samani” date-palm fruits.

The effect of growth regulators such as: Naphthalene Acetic Acid “NAA” (80 and 90 mg/l at hababak stage and 50 and 60 mg/l at the beginning of fruit color break).

and N-2-chloro-4-pyridyl-N-phenylurea “CPPU” (5 and 10 mg/l at hababak stage and 10 and 15 mg/l at the beginning of fruit color break) on yield and physico-chemical characteristics.

were investigated In addition, the effect of dipping the fruits in oils such as: lemongrass (0.4 and 0.8 % ) and peppermint (4 and 8 % ) and cold-storage durations of zero, 15, 30 and 45 day on physico-chemical characteristics (weight loss, total soluble solids content (TSS), acidity, TSS/acidity ratio, tannins, chlorophyll and carotene) were evaluated during storage period.
