The Influence of edaphic factors on the level of some physiological parameters for Lycium shawii in Taba Protected Area, Egypt.

Abstract

The aim of this article is assess the influence of environmental factors (especially edaphic) on the level of some physiological characteristics of plant communities in Taba Protected Area (Taba PA), South Sinai region. The Taba Protected Area (TPA) is one of Egypt's largest protected, about 2850 km2 (Lat. 29° 32´ N, Long. 34° 46´ E, Alt. 500 m a.s.l.),In International Protection Category III (In accordance with IUCN). Results showed that edaphic factors have an important role at variation in biochemical contents of plant communities within the selected wadis. The soils of study area, as desert soils (Arid soils), where soil properties vary over quite small distances, the causes of this variation due to some environmental factors such as gradient on the elevation, temperature, and rainfall between different locations..Four samples of Lycium shawii were collected from four studied locations. Evaluation of present methods used for analyzing the major biochemical contents (Soluble Carbohydrate, Water Soluble protein, Proline and Photosynthetic Pigments). Results were statistically analyzed by using One-way ANOVA and Post hoc-LSD tests (the least significant difference). In this study, prominent variation was recorded as regards the biochemical constituents of the plant among the different wadis.
