An anatomical study of leaves and petioles of Pistacia mutica in Maravehtapeh, Golestan province of Iran

The genus Pistacia family an Anacardiaceae has 33 species in the world four of which have been reported from Iran. The purpose of this study is to compare the sixmember anatomical structure of wild pistachio male and female and measure the taxonomic use of these traits. In this study, the trait characteristics of leaf and petiole of a species P. mutica from Maravehtapeh area of Golestan province were investigated. The vegetative samples collected in the carnivorous fixative solution were then prepared in a manual manner after being colored with carmen and methyl green color and slides they were studied by optical microscopy. The results of the leaflet analysis showed that the leaf type was seen from the type of curvature and in the central vein of the tissues of the collenchyma, Parenchyma, Sclerenchyma and elliptical vascular beds. The petiole anatomical structure is similar to the ellipsoidal cross section of the leaflet vein. Also,there was no significant difference between male and female pedigrees in terms of leaf and petiole anatomical traits.
