| Abstract | ||
| The present work aimed to study the effect of habitat conditions on the total rude protein, total amino acids and protein electrophoresis in some range species growing naturally in wadi El-Gafra. _ Four species were investigated from two different habitats viz., up stream ortion of Wadi EI-Gafra, near the high way at 63km west of Suez and Mid stream portion of the same Wadi just N-NW EI-Asher Min Ramadan City Egypt. These species included Panicum turgidum, Forssk; Lasiurus hirsutus, Forssk; Tamarix mannifera, Ehrenb. And Nitraria retusa, Forssk. The results indicated that there were variations in the concentrations of total crude protein and protein amino acid of plants in response to habitat conditions, i.e., the species of xeric habitat (Panicum turgidum and Lasiurus hirsutus) accumulated cyclic amino acids less than the other species which collected from saline habitat (Tamarix mannifera and Nitraria retusa). Also the studied halophytes accumulated proteins with low molecular weight than xerophytes species. | ||
