Leaf, Stomata and Trichome Morphology of the species in Carpinus Genus
The species of Carpinus genus are widely distributed in the Hyrcanian and Arasbaran forests. Previous researches identified the species only by leaf and seed macro-morphological traits. Leaf morphological variations in the different ecological conditions led to some problems in taxonomy of the genus...

| description | The species of Carpinus genus are widely distributed in the Hyrcanian and Arasbaran forests. Previous researches identified the species only by leaf and seed macro-morphological traits. Leaf morphological variations in the different ecological conditions led to some problems in taxonomy of the genus. In the current research for first time, stomata and trichome morphology were surveyed on plant collections of Noshahr Herbarium by scanning electron microscope (SEM) and light microscope (LM). Some plant samples were collected from natural sites by the authors. First, separation accuracy of Carpinus betulus, C. schuschaensis and C. oreintalis was investigated by multivariate analysis. Extracted components of Principal Component Analysis (PCA) were highly correlated with some leaf size parameters but could not clearly separate the three groups. Discriminate analysis proved accuracy of grouping about 64.7%. Carpinus betulus had the largest dimension in stomata and trichome trait while C. orientalis had the smallest about this trait and C. schuschaensis had the medium size between of two species. Stomata type in C. betulus was paracytic, anomocytic, and Anisocytic and C. oreintalis were laterocytic and C. schuschaensis was Anisocytic and laterocytic. In contrast to other species, cells of stomata located upper than epidermal cells in C. betulus. Simple unicellular trichome was determined for the genus. Although the size and dense of trichome on the leaf and petiole were different among three species, these traits were highly associated with ecological conditions. We concluded that these traits did not have any taxonomic significant in the genus. The current research calls for seed and bract morphology as well as molecular markers to be revised. |
