Abstract
Photosynthetic performance of six tropical evergreen forest species, representing three successional groups was studied using the chlorophyll fluorescence technique. The study showed that the maximum photosynthetic efficiency could be seen under less light conditions in Palaquium ellipticum and Cullenia exarillata and in high light conditions in Macaranga peltata. The study also showed that in species such as Actinodaphne bourdillonii and Clerodendrum viscosum, analysis of photosynthetic performance alone might not be sufficient to categorize them into different successional groups. Thus, an integrated study on phenology, growth and survivability patterns and photosynthetic performance of tropical evergreen species to assign them the successional status is suggested.
