Ecological evaluation of some physiochemical parameters in Blepharis sindica T. Anders-a vulnerable medicinal plant of the arid region

The present paper deals with physiochemical responses in Blepharis sindica, a vulnerable medicinal plant of the Indian Thar desert. Different physiochemical parameters such as leaf moisture percentage, osmotic potential, leaf pigments, proline, total sugars, crude protein and phosphorus contents varied significantly according to different growth phases of the plant. Maximum amount of soil moisture percentage was reported in deeper (20-25cm) layers, while leaf moisture and crude protein in July. Higher values for proline and total sugars were found in late season, i.e. November and December, whereas total chlorophylls and phosphorus during middle of season, i.e. August to October.
