Abstract
The present study was conducted during 2012 and 2013 seasons on “Zaghloul” date palm 
fruits. Spathes were sprayed three times at growth start, after fruit setting and at one month 
later with four substances namely Amino acids enriched with micronutrients (Fe, Zn, Mn, B 
and Mo), Sugar alcohol enriched with micronutrients (B, Fe, Mn, Zn and N), Algae extract 
formulation containing (potassium oxide, phosphorus oxide , N, Zn, Fe and Mn) in 
concentration of 2% and Licorice root extraction (Glycyrrhiza Glabra L.) in concentration of 
7%. Sprayed fruits were harvested at khalal stage and immersion in 1% chitosan as 
postharvest application and then fruits stored up to 3 months at 0°C and relative humidity 
(RH) 90-95% in order to study the effect of all treatments on fruit quality and storability of 
“Zaghloul” date palm. All treatments increasing fruit firmness, total soluble solids (ºBrix) 
and total sugars and decreasing weight loss percentage, discarded percentage, and total 
soluble tannins as compared with the control treatment. The best results with regard to fruit 
quality and storability of “Zaghloul” date palms were obtained with spraying licorice root 
extraction three times and immersion in 1% chitosan.
