Total nonstructural carbohydrate concentrations as a function of predawn water potential. Different colors in dots and lines correspond to light-exposed (blue) and shaded (red) individuals before the drought experiment. Solid regression lines and 95% confidence intervals (gray-shaded areas) depict significant relationships. Coefficients of determination and p values are included for each light treatment. Similar figures of total NSC concentration dynamics as a function of predawn water potential for three different organs are provided in Appendix Figs. 14–16
