Fig. 7. Total nonstructural carbohydrate accumulation during 5-d shade and water deficit treatments in florets sampled at the pre-pollination stage (a) and composite endosperm/nucellus tissues sampled at the post-pollination stage (b). Nonstructural carbohydrates was calculated as the change during the 5-d stress period of the sum of glucose, fructose, sucrose, and starch in tissues.
