Genetic diversity of leaf photosynthesis under fluctuating light conditions among temperate japonica rice varieties.

Abstract excerpt

Under field conditions, solar radiation on a crop canopy fluctuates according to clouds, wind, and self-shading. The slower response of photosynthesis compared with the rate of irradiation changes leads to loss of photosynthetic carbon gain. Although some genetic differences in the rate of photosynthetic induction have been reported, the diversity among rice varieties is largely unknown. Here we evaluated genetic...
