Results revealed significant effects of kaolin on fruit size, flesh/stone (wet weight), flesh/ stone (dry weight) and oil contentof the fruit. Kaolin did not significantly affect oil content in wet matter. The highest fruit size, flesh/ stone (dry weight) belonged to 2.5% kaolin while the lowest was related to  control. Highest vs. lowest wet weights of flesh/ stone were attributed to 5% kaolin vs. control, respectively. In contrast, a maximum of oil content went to control, while a minimum belonging to 2.5% treatment.
