Effect of different Pollens on Some Characteristics of Date Palm Phoenix dactylifera L. Cvs. Bream and Kahdrawi

Abstract

The present study was carried out during the growth season (2008) in Alhartha( Abu skhair) a region in Basrah, two male cultivars were used ( Ghanamy akhdar, Khikri adi & Mixture of both of them) to pollinate Bream & Kahdrawi female cultivars. Ghanamy akhdar had the significant effect in increasing average fruit weight at kahlal stage(8.09 ) gm , average mesocarp weight(7.10 ) gm and average seed weight (1.03 ) gm compared to other pollens treatments. Ghanamy akhdar also increased average fruit diameter (20.92 ) mm , average fruit length (30.58 ) mm and average fruit size(7.53 cm3) , Ghanamy akhdar increased percentage total sugar (57.16)% , percentage reducing sugar(36.64)%, percentage sucrose(18.02)%, average dry weight(2.06) gm & percentage total soluble solid (23.63)%. Bream cultivar had the highest fruit total characteristics compared to Kahdrawi such as percentage of total sugar(55.48)%, percentage reducing sugar (39.94)% , percentage sucrose(15.85)% , average dry weight(1.97)gm , average seed weight(0.87) gm and average mesocarp weight(6.12) gm . Ghanamy akhdar percentage reduced fruit abscission to (11.69)% , whereas Bream cultivar percentage lower fruit abscission (17.93)% compared Kahdrawi cultivar.
