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

الملخص EN

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.
