Abstract
This study was carried out during two successive seasons 2018 and 2019 at the orchard of Faculty Agriculture, Assiut University. The aim of this study was to investigate the effect of spraying with GA3 at 100ppm, combined with BA at 50 ppm and/or IAA at 100 ppm on some physical and chemical characteristics and yield parameters of Sewy and Hayany date palm cultivars. The obtained results showed that all combinations of the used growth regulators decreased the fruit set and fruit retention percentages of both tested cultivars, while the average bunch weight (kg) and average yield weight (kg/palm) increased by these treatments during both studied seasons. Moreover, the fruit weight (g), flesh weight (g), fruit volume (cm3) and flesh volume (cm3) significantly increased as affected by all growth regulators applications for Sewy and Hayany cultivars during 2018 and 2019. All applied treatments of GA3, BA and IAA combinations decreased total soluble solids percentage (T.S.S%), reducing and total sugar content of Sewy and Hayany fruits, while it increased acidity content for both cultivars.
