EGO-PHYSIOLOGICAL STUDIES ON ALHAUl PSEUDALHAGI (M. BIEB.) DESV. EX B. KELLER & SHAP. IN GANGANAGAR DISTRICT (RAJASTHAN)

摘要

Alhagi pseudalhagi (M. Bieb.) Desv. ex B. Keller & Shap. an economically and medicinally important plant was studied under various eco-physiological conditions in Ganganagar District of Rajasthan. Phenological studies revealed that the plant completes its life cycle before the onset of winter season. Phytosociological analysis showed that the two communities studied (Erigeron- Ageratum- Coronopus community- UB site and Ageratum- Nicotiana- Cyperus community- AM site) were sufficiently similar in respect of their constituent species as indicated by the high community coefficient (54.368). The vegetation at both these localities was dense and heterogeneous. Chemical constituents showed positive correlation with the standing crop of above ground biomass. Seeds required scarification with concentrated sulphuric acid for germination. The germination is epigeal and required 2- 5 days in continuous light.
