Abstract excerpt
Elevated CO2 increases, while high temperature decreases, rice yield. We hypothesized that the interplay between these opposite effects varies across genotypes and these variations are associated with the ability of genotypes to avoid and tolerate stress. We evaluated a Japonica genotype (Changyou5) and an Indica genotype (Yangdao6) under combinations of two CO2 levels (ambient and enriched to 590 μmol mol-1) and...
