Title Anatomical and physiological responses of three species of Suaeda Forssk. ex Scop. under different habitat conditions
Source Journal of Applied Sciences Research
Abstract Three species of Suaeda were collected from different saline sites of Egypt. S. vera and S. pruinosa collected from coastal sand dunes (site-1) and salt marshes (site-2) at the Northwestern coast. While S. vermiculata collected from dry upper zones of salt marshes (site-3) and salt marshes (site-4) at Northeastern coast to assess their mechanism of adaptation to the different saline habitats. Anatomical modifications in leaves in relation to succulence, photosynthetic pigments and ABA contents were studied. Results showed that leaf cross section area, leaf thickness, epidermal tissue area, photosynthetic carbon assimilative tissue area (mesophyll), water storage tissue area, and chl. a were significantly decreased in the three species collected from the high saline habitats. While, cuticle thickness, number of xylem rows/median bundle and percentage of epidermis tissue were increased. On the other hand, the water storage tissue did not affected by the different saline habitats. High percentage of the vascular bundles and ABA content were detected in S. vera leaves. While it decreased in photosynthetic carbon reductive tissue area (bundle sheath) and succulence under salt marshes. S. pruinosa kept stability in photosynthetic carbon reductive tissue area and its percentage, succulence, chl. b and carotenoids, while the leaves increased in vascular bundles area and decreased in inner diameter of xylem vessles and ABA content under salt marshes. S. vermiculata uneffected significantly in percentage of vascular bundle tissues while the leaves decreased in photosynthetic carbon reductive tissue area, vascular bundle area, inner diameter of xylem vessles, degree of sucuulence and photosynthetic pigments and increased in percentage of photosynthetic carbon reductive (kranz type) and ABA content.
