Summary
The internal resistance r i, to carbon dioxide diffusion was separated into the mesophyll and the carboxylation components, and it was shown that the mesophyll and the carboxylation resistances r m and r x had similar order of magnitude, suggesting the importance of both in the photosynthesis of Hevea brasiliensis.
