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 0.2% and Licorice root extraction (Glycyrrhiza Glabra L.) in concentration of 0.7%. Sprayed fruits were harvested at khalal stage in order to study the effect of all treatments on fruit quality of Zaghloul date palm. All treatments increasing (fruit weight, fruit dimensions, fruit volume, total soluble solids (ºBrix), total sugars and total anthocyanin) as compared with control treatment. The best results with regard to fruit quality of Zaghloul date palms were obtained with spraying licorice root extract at three times.
