Effects of Dry and Wet Seasons on Some Soil Minerals and Proteins in some Plants

Abstract

s: The Kingdom of Saudi Arabia consists of several regions with different varied climatic conditions. Eastern Saudi Arabia has a subtropical desert climate, arid basically because of its geographical situation in global patterns of atmospheric circulation. Low rainfall and high temperatures certainly class the area as a desert; five plants samples were collected in the year 2012 from different locations and different distances; they were Zygophyllum album, Halopeplis perfoliata, Cyperus conglomeratus (A) (B), Zygophyllum decumbens. Some soil minerals (Cl - , Na + , K + , Ca ++ , Mg ++ , B +++ ) and proteins concentration were investigated during dry and wet seasons. In the dry season, tested minerals concentrations increased and the difference between concentrations were significant at p > 0.05, the protein contents decreased as a result of salt and water stress , the difference between concentrations were significant at p > 0.05, while in the wet season, the minerals concentrations of the soil decreased, the difference between minerals concentrations were significant at p > 0.05; the proteins content increased, and the difference between concentrations were significant at p >0.05. The littoral salt marshes show different results during dry and wet seasons, because of the character of the soil of these habitat. Key wards: Soil minerals, Proteins, salt stress, temperature stress.
