Leaf Anatomical study of Populus L. (Popoulus nigra, P.alba, P. euphratica & P. caspica) (Salicaceae) in Iran
Journal Title: Scientia Agriculturae - Year 2015, Vol 11, Issue 3
Abstract
Populus (Salicaceae) comprises four species which are distributed in different parts of Iran. Poplars are of economic, ornamental and medicinal importance. In present project Populus nigra , P. euphratica , P. alba , P. caspica . are studied. Due to difficulties in P. alba and P. caspica identification and presence of intermediate forms in P. nigra, main aim of present study is to study the leaf cross sections of taxa to find diagnostic features. By considering 30 qualitative and quantitative leaf anatomical features we found that main differences between studied taxa were in midrib shape, hair condition and spongy mesophyll layer. Leaf anatomical features showed taxonomic value in Populus specie separation. All four studied specie are clearly separated. There are leaf anatomical similarities between P. alba and P. caspica due to similar lower epidermis thickness, number of spongy layers in mesophyll and hair presence in lower leaf surface. P. euphratica shows a separate position by features as lower epidermis thickness, leaf diameter to mid rib diameter and absence of spongy mesophyll.
