Effect of Pollen Grains and Growth Regulator NAA on Some Fruit Characterization of Date Palm Phoenix Dactylifera L Cultivar. Sultani

Abstract

This research was conducted in orchard belong to Al-Mahawel date palm station (Abo Sderah) / Ministry of Agriculture located in governorate of Babylon, during the season 2015-2016. Twenty four uniform date palm Phoenix dactylifera. L. Sultani cultivar were used , to study the effect of the pollinator type(P1: Ghannamiakhder , P2: Ghannamiahmer and P3:khukri ), the concentration of Naphthalene Acetic Acid NAA(0 , 50 and 100 ) mg.L-1 and their interaction on fruits setting up , fruits drop and some of physical and chemical characteristics of fruits of date palm Sultani cultivar .Experiment carried out as factorial experiment(3×3) by Randomized Complete Block Design (RCBD) with three replications in each treatment , and the means were compared using LSD level of significant test at P ≤ 0·05. The results can be summarized as that Ghannamiahmer (P2)cultivar and 50 mg.L-1 NAA application showed a significant increase in the fruit setting% , while Khukri cultivar(P3) showed significantly increased fruit size and weight as compared with the other cultivars.Furthermore the cultivar(P1) obtained a significant increase in the bunch weight in Rutab stage as compared with the other cultivars. While the cultivar (P2) with 100 mg.L-1 NAA application showed significant increase in bunch weight in Rutab stage as compared with the other interactions. Ghannamiakhder (P1) cultivar had a significant increase in the fruit content of reducing sugars and non-reducing sugars, while khukri showed significant increase in fruit content of dry matter% and total sugars as compared with the other cultivars.

Effect of Some Growth Regulators on Yield and Fruit Quality of Sewy and Hayany Date Palm Cultivars

“…(198.15 cm 3 ) in 2019 season compared to control and other treatments. The results are in agreement of those reported by Aubied and Hamzah, 2019).…”

Effect of Different Pollen Sources on Yield and Fruit Quality of Barhi Date Palm Cultivar under Sudan Conditions

“…Therefore, pollen source (male trees) has significant effect on fruit yield (Omar et al, 2014). In addition pollen grains effected directly the quality and the quantity of the fruits (Soliman and Osman, 2001;Farag, 2012;Hafez et al, 2014;Aubied andHamzah 2019 andmonir, 2020). Generally it could be safely concluded that Male (1) or M (6) were superior to pollen Barhi date palm as increased significantly the studied fruit quality (Metaxenia) especially fruit set, bunch weight total yield, physical characters in most cases as compared to the other Males…”

Evaluation of Different Insecticides Against Lesser Date Moth, Batrachedra amydraula Meyrick, 1916 (Lepidoptera: Batrachedridae) under Field Conditions

“…The date palm tree is one of the sweetest, full nutrient, and oldest fruit crops in North America and the Middle East, especially in North African countries and Arabian Peninsula, had been cultivated about 7000 years ago (Flower et al, 2019) and have a vital character in commodities of daily life (Sallon et al, 2020). These fruit-bearing oldest trees grow well in different countries around the world in severe environmental conditions (Iubied and Hamzah, 2019). In the cultural heritage of the Arab region, the date palm possesses crucial significance in history being the most ancient, cultivated crop 3300-3100 BC (Paszke, 2019).…”
