In order to study the effects of macro-elements and micro-elements of pollen on pollen germination in pistachio, a experiment was conducted by selecting 11 different male pistachio trees. The specimens were selected from staminate pistachio trees in Kerman, Iran. The pollen analysis was done at Horticulture and Food industry, University of Budapest at Hungary. Amino acids and minerals had profound effects on pollen germinability. There was a positive correlation between pollen germination and the amount of glycine, luecine, xsyrosine, phenylalanine and arginine. The difference between maximum and minimum amount of the above amino acids varied from 15 to 50 percent. However, the amount of unit increase between highest and lowest level of pollen germination was about 66 percent. It seems likely that at least for some amino acids such as tyrosine, high ranges of variability are needed to produce large differences in pollen tube formation. Minerals such as Al, Cu, Na and N resulted in positively high correlation with pollen germination, with correlation coefficients of 75., 78., 71 and 70 respectively. The overall results of these observations were presented and discussed.
