Differences between genotypes of tomato (Lycopersicon esculentum Mill.) in net photosynthesis, light absorption by leaves, chlorophyll content and specific leaf fresh weight under low-energy conditions.

Abstract

Differences in net photosynthesis between tomato genotypes, grown under low light intensity and, from day 30, at 3 night temperatures, were largely due to differences in the capacity of the leaves to absorb light. Variation in chlorophyll content and leaf thickness largely explained the differences in light absorption. Genotypes with large thin leaves and a high chlorophyll content were thought to be best adapted to low-energy conditions. (Abstract retrieved from CAB Abstracts by CABI’s permission)
