Influence some Environmental Parameters on Growth, Physiological and Chemical Properties of Ricinus communis plant at some Al Gabl Al Khder Regions, Libya

This study focused on Ricinus communis plants collected from two distinct regions—Al-Bayda and Derna—located in the Al Gabal Al Akhder mountain range in Libya. The objective was to compare various chemical and physiological parameters of the plants from these two locations. Parameters such as leaf area, fresh and dry leaf weight, tree diameter, plant height, chlorophyll a and b, carotenoids, and starch content were analyzed. Additionally, the levels of certain metals and minerals in both plant and soil samples were assessed.The results revealed differences in physiological traits like plant height and leaf area between the two regions. These variations were attributed primarily to environmental factors, including differences in temperature, pressure, location, and soil composition.
