Effectiveness of ground-level education awareness programs among the indigenous communities to conserve threatened medicinal plants of the Aravalli hills of Rajasthan, India

In the Aravali hills of Rajasthan (northwest India), assessment of threatened medicinal plants were carried. Attempts were also made to conserve these plants by running education awareness programs at the adjacent villages of Aravali hills located at Jaipur, Udaipur, Banswara, Pratapgarh, Dungarpur and Chittorgarh districts. The study clearly indicates that there is an urgent need to trigger community-based approaches to conserve the threatened plants.

Drought-induced changes in photosynthetic performance of Triticum aestivum L.

Drought stress has multiple effects on the plantdevelopment. Photosynthesis is one of the key metabolic processes which determine plant productivity. The objective of present study was to understand the effects of drought stress on wheat var. [HI-1531(Harshita)] through fast chlorophyll a fluorescence analysis (OJIP). Various phenomenological parameters suggest that mild drought stress have no significant effect on the primary photochemistry of photosystem II (PSII) in var. HI-1531. The light harvesting complexes was found stable even in severe drought stress.
