Abstract

 Leaf, stem and nut of PISTACIA VERA (Ohady and Kaleh_ Ghochi) were examined during this study to characterize their ANATOMY structure with electron and optic microscope; also the effects of SALINITY on ANATOMY structure of leaf were studied. From an anatomical study they appeared that between two varieties, density of simple and glandular trichomes in leaf surface, the density of wax, the thickness of leaf, the length of epidermal cells, palisade parenchyma cells, the density of crystals in mesophyll and the manner of compatibility two varieties to SALINITY are different; But there is no difference between two varieties about ANATOMY structure of stem. SALINITY, increase density of simple trichomes and glandular trichomes especially in adaxial surface and decrease density abaxially. The results, in this research (references to tables and figures) were proved that compatibility in Ohady variety is more than Kaleh_ Ghochi. In Iran, the highest incidence of DEFORMITY of pistachio nut occurred during April when shells were developing (Deformity nut is smaller than normal nut and Endocarp is not safe). In this research, the effect of SALINITY and MECHANICAL WOUNDING on DEFORMITY of nut was studied. The results showed MECHANICAL WOUNDING (that anyhow is symbol of sting of insects or hailstone or rain) has not effect on DEFORMITY of nut. With enter stroking until 15 days after full bloom all nuts fall in. But after 15 days, some Pistachio nuts remain that these nuts have safe endocarp and the shape of these is normal. So there is direct relation between growth of nut and its resistance. Also SALINITY increase resistant of nuts to MECHANICAL WOUNDING. The results of this study suggest that In EC=7.6, 12.6 DEFORMITY of nut is not related to crop load.
