Abstract

Increasing carbon dioxide concentrations and associated climatic changes have pronounced effects on carbon storage in ecosystems. This, in turn, is likely to affect C/N ratios of the plant material with possible effects on decomposition cycles. Hence, it becomes important that at local levels mechanisms of CO₂ interactions with water, light, nutrients and temperature should be investigated, and the effects integrated in order to quantify the cumulative impact of CO₂ increase on biomass production. This article discusses importance of parameter ‘G’ in connection with maximum increments in plant volume, and provides models for certain important Indian species.
