Photoinhibition of photosystem I under high light in the shade-established tropical tree species Psychotria rubra

The photosynthetic sensitivity to high light differs among understory plants of shade- and sun- established tree species. Shade-established tree species are sensitive to high light but the underlying photosynthetic mechanism has not been fully resolved. In the present study, we examined the responses of photosystem I (PSI) and photosystem II (PSII) to high light in shade leaves of a shade-estab...

Pharmacognostic Studies of the Jatropha Curcas Leaves

The J. curcas is considered as a biofuel plant, but the leaves are traditionally used as an antiinflammatory and anticoagulant. In present investigation, the detailed pharmacognostic study of J. curcas leaf is carried out to lay down the standards which could be useful in future experimental studies. The study includes macroscopy, microscopy, preliminary phytochemical screening and physicochemi...
