Abstract Plant performance usually reflect the environmental factors prevailing in a certain habitat. This study aims to investigate the effect of different habitats on six wild plants; Alhagi graecorum Boiss., Calligonum polygonoides L., Cynanchum acutum L., Deverra tortuosa Desf., Hyoscyamus muticus L. and Phragmites australis Cav., on growth related traits, anatomical, mineral composition, biochemical and molecular levels. Soil and plant samples were collected at the same time from manmade forest irrigated with wastewater and deserts outside the forest during summer and winter seasons at Sadat City, Menoufia governorate. Wastewater and soil properties were analyzed. The plants biochemical products including total (carbohydrates, proteins, amino acids, lipids, tannins, phenolic compounds, flavonoids, alkaloids and saponins) were determined. The genetic makeup of the studied plants from the different habitats were investigated using five RAPD primers. The results indicated that irrigation with wastewater caused an increase in EC, TDS and ion concentrations for soil samples collected inside forest compared to those collected from outside. Also, wastewater irrigation increased significantly plant height, leaf area and number of leaves/plant. The biochemical contents varied in plant samples collected from inside to outside forest during summer and winter seasons. Molecular fingerprints revealed different profiles for the five plants collected from inside forest compared to outside ones during summer and winter. In conclusion, the variation in habitats exerts remarkable effects on growth related traits, anatomical traits, mineral composition, biochemical products as well as the genetic fingerprints of the studied plants. |
