Spatial variability of C-13 isotopic discrimination in corn.

Water stress influences photosynthesis induced isotopic 13C discrimination in C3 and C4 plants. In C4 plants, 13C discrimination increases with increasing water stress, while in C3 plants the opposite is true. The amount of 13C discrimination that occurs is a function of plant type, interactions ... Read More
