Anatomical studies some of Salsola and Atriplex species in the Garmsar province

The genus Atriplex L. and Salsola are belongs to chenopodiaceae. in this research، anatomical studies of stem، leaf and petiol on three species of Salsola and three species of Atriplex genus have been studied. Various anatomical characters such as; shape of stem، cortical parenchyma and collenchyma، spongy and palisadic paranchima، vascular bundles midrib and stomata type were very different between species. Species were easily separated from each other by mean of anatomical characters. Of these: S. arbuscula، S. kalisubsp ruthenica، S. tomentosa A. tatarica، A. leucoclada، A. griffithii Specimens of three species of genus Salsola and Atriplex that were mostly obtained from fresh herbarium and filed specimens in fruiting stage and then put in glycerin-ethanol (1:1) for a month. Hand cross sections were made from the middle part of petiole، stem and leaf. These sections were strained with Carmen and Methyl blue and photographed by light microscopy Nikon model Alphashot 2YS2 and Canon The results obtained confirm the usefulness of leaf anatomy characters for the identification of most of the species studied as has been traditionally recognized variable characters for distance between species. The results of this studies show that our studies anatomical of leaf can be considered used to separation between species this genus.
