Abstract
Wadi El-Hawashiya is one of the most important wadis of the Eastern Desert of Egypt that occupies a specific position in the Gulf of Suez area. Annually, it receives 10 mm rainfall adding to annual storms creating flash floods that put the wadi on attention focus for sustainable development. The present investigation aims at recognition, identification of floristic components and evaluation of the nutritive value of vegetation as an ecophysiological adaptation towards the accident environmental stresses, through clarifying the chemical composition of the dominant species during different successive seasons. Phytosociologically, the results indicated that the co-dominant Zilla spinosa-Zgophyllum coccineum community type dominated the upstream portion of the wadi bed, while Artemisia herba-alba and Zilla spinosa communities dominated two different sites at the midstream portion. The surveyed plants were classified according to their palatability into three groups; high palatable, low palatable and unpalatable. Also, the results showed that the variations in edaphic factors, especially soil texture, salinity, moisture contents and sharp-ct sloping at the wadi bed, play important roles in the distribution and growth of plants and in accumulation of osmotically active constituents inside the plant tissues. Ultimately, results of the present work indicated that there is an intimate relationship between accumulation of K+ ions and the formation and account anion of carbohydrates.
