Research Interest:
Ecophysiology of tropical plants
Research is actively focused on studies on developmental,
physiological and biochemical processes in tropical plants, so as
to understand how they adapt to environmental stresses (high light,
drought, salt stress, high/low N, anoxia). The extent to which these
processes are engaged in nature is also under study. Ultrastructural
changes in plants in response to environmental stresses are also
conducted.
Brief descriptions of on-going studies:
- Gas-exchange and chlorophyll fluorescence studies of fern
gametophytes/sporophytes, secondary forest plant species, cassava
and rice to determine photosynthetic performance and stress
adaptation.
- Activity of superoxide dismutase in plants in response to
stress conditions.
- Effect(s) of nitrogen availability on photosynthetic adaptation
of cassava and sorghum to high light and cyanogenic potential.
- Crassulacean acid metabolism and its significance in plants
of the humid tropics.
- Photosynthesis and growth of Acacia mangium.
- Responses of gametophytes of the mangrove fern, Acrostichum
aureum, to flooding.
