EFFECT OF SOURCES OF POLLEN GRAIN AND IT EXTRACTION AND NAA GROWTH REGULATOR ON SOME CHEMICAL AND PRODUCTION CHARACTERISTICS FOR DATE PALM FRUIT CV. HILLAWI

Abstract

This study was carried out in privet orchard at Abo-Akhaseb region-Basra. to study of the effect of pollen sources (Ghannami Akhder and Khekri Adi) , it extraction and NAA on chemical characteristics( reducing sugar , sucrose , total sugar, TSS, Acidity and Dry weight) and some physiological and production characteristics (dropping fruit and tree production) for Date palm fruit cv. Hillawi . the pollinated fruit was sprayed by pollen extraction (2gm/l) and NAA(25 mg/l) at 30 and 45 days after pollination. The results showed asignificant effect of pollen of Khekri Adi in most of chemical and production characteristics, and conclusion the metaxenia effect may be caused by endogenous pollen hormones.
