Abstract
This study aimed to provide a detailed description of fluorescent and environmental features of societies vegetable accompanying sex Alratrit in Egypt: the leaf pen (Zygophyllum coccineum) in each of the northern desert Majesty area of the Eastern Desert and the coast of the Mediterranean region Aldltaoa in Egypt as well as clarify the economic importance of this plant. The description of life styles in the regions of the study was estimated percentages for each model and found that yearbooks (Therophytes) represents a first-class mainstream of the two regions has achieved a rate of% 46.83 followed by the phenomenon plant model (Chamaephytes) who investigated the proportion who achieved ratio% 27.84 followed by semi-model Almokhtviac by (Hemicryptophytes), which achieved a rate of 11.39% followed by Almokhtviac model (Cryptophytes) increased by 7.59% and flowering plants Kspah model (Nanophanerophytes) increased by 6.67%. The analysis said fluoro of the study area there are 32 species% (40.50) of the registered plants follow the Mediterranean element (Mediterranean) either Dual zone element (Biregional) has such ratio% 20.25, was also recorded 24 species (%30.37) botanically trace deserts element -asindi (Saharo-Sindian) it was found that these three fluorescent elements is considered the key elements of the regions of the study either fluorescent rest of the other groups, it was represented poorly represented. Using the classification program and bi-directional sequence (TWINSPAN) identify the four botanical groups has found that the distribution of sovereignty in these plant communities was as follows: group (A), which included seven sites Zygophyllum coccinum may be overwhelmed by the group (B), which included 22 site was overwhelmed Zygophyllum coccinum while the group (C) included 14 site, which was marked by a joint sovereignty between each of Zygophyllum coccinum and Haloxylon salicornicum either group ( D) included 17 site was overwhelmed Haloxylon salicornicum.Using Alttabqa canon Distribution Program (CCA) has been possible to identify the most important soil influential factors in the distribution and abundance of plant collections in the different environments in the regions of the study and these factors include: the content of the mud and the pH of the soil and sulfates and the percentage of adsorption of sodium and sodium cation and electrical conductivity and magnesium and alerted adsorption of potassium and potassium organic carbon cation.Also, the present study aimed to compare between the desert and coastal plant regarding its contents of protein, proline, pigments, carbohydrate, ascorbate, glutathione, phenols, flavonoids, tannins, saponine, alkaloids. In addition, the study aimed to investigate the activities of pyruvate kinase, phosphogluconate dehydrogenase, pyruvate dehydrogenase and glutamine synthetase.The results of these experiments showed that: The contents of protein, proline, pigments, carbohydrate, ascorbate, glutathione, phenols, flavonoids, tannins, saponine, alkaloids. It was observed that the contents of these compounds were higher in desert plant than in coastal plant. The phytohormones studied including indole acetic acid, zeatin, coumarin resulted in activating phosphogluconate dehydrogenase isolated from Zygophyllum coccineum leaves. It was observed that zeatin was the most effective compound and the desert plant exhibited the higher activity compared to the coastal one.The various extracted prepared from the leaves of the desert and the coastal plants expressed inhibitory effect on some tested bacteria which are pathogenic. It was found that methanol was the most active extract particularly for the desert plants.The allelopathic effect of aqueous extract of Zygophyllum coccineum was tested on the seed germination and radical length of Chenopodium album.The results showed that Zygophyllum coccineum leaves extract reduced both the seed germination and radical length in a concentrationdependent manner.
The amino acid analysis of Zygophyllum coccineum leaves showed that desert plants contained several amino acids and the most dominant amino acids were cysteine, methionine, proline, alanine and glutamic acid. However, the coastal plant contained cysteine, methionine, proline, leucine, glutamic acid, alanine and glycine were the most dominant ones.Measuring the antioxidant activity usind DPPH method revealed that the desert plant wasmore active than the coastal plant The active consistuents found in the desert as well as in coastal plants were analyzed. It was found that the desert plant contained 8 compounds and the coastal plant contained 14 compounds.
