Comparative Anatomical Sections Sections Of The Attlas Pistachio In Rechaiga, Tiaret (Algeria)

Abstract

This work is part of the anatomical study of the leaves of the Atlas pistachio in the Rechaiga region of Algeria and the stomatal density. Transverse sections were made on the central part of the leaflets of male and female individuals. The results obtained showed that the response of the selected individuals to environmental constraints is different and shows a high polymorphism. Thus, they show that this species has a thick cuticle layer and a thick mesophyl to reduce a maximum of water in the presence of drought. They also show that the distribution of stomata varies among the selected trees. Pistacia atlantica Desf. is a species of great virtue where it is necessary to appreciate and protect it.
