Abstract :
Vitis vinifera L. is one of the most important plant products in the world .The aim of this study was to investigate the anatomical structure of leaves and petioles of seven grape cultivars of Boroujerd region with light microscopy. Different anatomical features such as leaf thickness, petiole diameter, diameter of vein and petiole vessels, diameter of leaf and petiole bundle, thickness of leaf and petiole epidermis, diameter of main vein, number of petiole and main vein clusters and diameter of brain parenchyma. According to the results, the highest leaf thickness, petiole diameter, diameter of vein and petiole vessels, diameter of leaf and petiole vascular bundle, diameter of petiole nucleus parenchyma and number of petiole vascular bundles were related to ruby cultivar. In the case of traits such as leaf thickness, leaf epidermal thickness, diameter of vein vascular bundles, diameter of leaf vascular bundle, main vascular bundles, the lowest value was shown by black grape cultivar. Manqa cultivar showed the highest leaf epidermis thickness and main vein diameter. The smallest diameter of the main vein, the diameter of a petiole bundle and the thickness of the petiole epidermis belonged to Fakhri cultivar. Asgari cultivar showed the highest value of main vein vascular apparatus and the lowest value of petiole diameter, diameter of petiole vascular bundles and diameter of petiole brain parenchyma. Sahebi cultivar showed the highest thickness of petiole epidermis. Comparison of anatomical structure of leaves and petioles showed significant differences in the studied indices in different cultivars.
