Abstract
Under natural conditions leaves of Hevea plants often experience either continuous or fluctuating light levels. Thus in this study three Hevea brasiliensis genotypes were compared for their response to such light environments simulated in the laboratory. It is evident that genotypes differ in their ability to maintain steady CO2 assimilation rates throughout the day under constant saturating light. Similar differences were apparent in the ability to maintain the induction states under low light levels. Further carbon losses could result due to the undershoot in CO2 assimilation rate when light levels are suddenly reduced. Genotypic differences in such non-steady state behavior of CO2 assimilation may contribute to differences in productivity.
