Abstract
This study was carried out in 2003 and 2004 seasons In the Experimental Orchard of the Faculty of Agriculture, Cairo University, Giza. Egypt, to study the effect of fruit thinning using NAA at different concentrations spraying on Samani and Zaghloul date palm cultiivars. Fruit set was decreased when NAA sprayed at 7 or 21 days from pollination especially at 100 or 150 ppm for both cultivars in the two seasons. Also, Samani and Zaghloul fruit physical characteristics i.e. (fruit weight, flesh weight, seed weight, fruit dimensions and fruit size) were enhanced with 100 or 150 ppm of NAA. In addition, Samani and Zaghloul fruit contents of TSS, total soluble sugars, reducing sugar an~ non-reducing sugars were increased with spraying 100 ppm NAA in the two seasons especially 7 days atter pollination.
