Abstract | ||||
The effect of fruit thinning using ethephon and cytophex at different concentrations and dates of application was studied on Samany date palm cultivar in two seasons (2003-2004). Fruit set percentage was much decreased when ethephon was sprayed at all tested concentrations within 13 days after pollination compared with cytophex, in the two seasons. Moreover Samany fruit physical characteristics i.e.. fruit weight. flesh weight. fruit dimensions and fruit size were enhanced with ethephon and cytophex treatments. In addition. Samany fruit contents of TSS. total soluble sugars. reducing and non-reducing sugars were increased when ethephon at 300 ppm and cytophex at 60 ppm were sprayed at 13 days after pollination. Key words: Samany date palm cultivar— ethephon - cytophex — fruit characters —— fruit thinning . | ||||
