A comparative study of the morphological and anatomical characteristics of the leaves of three date palm cultivars phoenix dactylifera L. in Hadhramout Valley and Coast

This study was conducted on three cultivars of date palms (Jazaz, Socotrai and Barhi) grown in different environments in the agricultural season 2020 in Valley and Coast Hadhramout region, with the aim of comparing the morphological anatomical characteristics of the leaves among themselves, by studying some morphological and anatomical characteristics of the leaves, And the results were analyzed using a randomized complete sector design. The results obtained showed that the environment factor had an effect on the number of leaves, the length of the leaf, the length of spines area and number of stomata. where the Hadhramout Valley region was significantly superior in the number of leaves and number of stomata, while the Hadhramout Coast region was significantly superior in the length of the leaf, length of Pinnae and length of the spines area, and the cultivar factor had an effect on studied characteristics, where the Jazaz cultivar was significantly superior in the number and length of Pinnaes, and Barhi cultivar was significantly superior in leaf length, number and length of spines, length of spines area, Pinnae width and lower epidermal thickness, while Socotrai cultivar was significantly superior in number of leaves
