Abstract：
:Levels of phenolic secondary metabolites in the leaves of four west African rain-forest plants,Acacia pennata, Cynometra leonensis, Diopyros thomasii, andTrema guineensis, were correlated with incident light intensity at both the inter- and intraindividual level. Enhanced phenolic levels under high light intensity appeared to be due to production of both polyphenolics (condensed and hydrolyzable tannins) and simple phenolics. InTrema guineensis, where it is possible to separate leaves in terms of both their age and the light incident upon them, condensed tannin production progressed differently during the development of "sun" and "shade" leaves, suggesting continuing production of new oligomers in the former but not in the latter. The results of this study suggest that the production of phenolics in relation to variation in incident light is a finely tuned process, which must be explained in terms of plant physiology and intermediate metabolism rather than in terms of resource allocation or a direct response to herbivory.
