Vegetation And Soil Relationships In The Inland Wadi Ecosystem Of Central Eastern Desert, Egypt, Fawzy Salama, Monier Abd El-Ghani, Noha El-Tayeh
Turkish Journal of Botany
In January 2010, torrential rains that had suddenly swept away a limited area in the Eastern Desert facing Qena Province in Upper Egypt resulted in the enriching of the vegetation of some extremely dry wadis at this location. A vegetation survey carried out shortly after this event, in April, revealed the prevalence of annuals in considerable abundance, which are hardly recognisable in such usually dry habitats. The normally scarce perennial vegetation had flourished, too. A total of 32 species, 11 annuals, and 21 perennials that belong to 27 genera and 15 families were recorded. The life-form spectrum in the present …

Cadmium-Induced Structural Disturbances In Pisum Sativum Leaves Are Alleviated By Nitric Oxide, Tuan Anh Tran, Valya Vassileva, Petar Petrov, Losanka Petrova Popova
Turkish Journal of Botany
In the present study, the protective effect of nitric oxide (NO) against Cd-induced structural disturbances in pea (Pisum sativum) leaves was investigated. Cadmium treatment resulted in a decreased leaf size and thickness of the lamina, reduced intercellular spaces in the mesophyll, small pavement cells, and a high density of stomata. These abnormalities were partially or fully reversed by a simultaneous application of Cd and the NO donor, sodium nitroprusside (SNP). The concentration of 1000 µM SNP was very effective in counteracting the adverse effects of Cd and resulted in leaf structural parameters close to those of the control leaves. These …
