1. Plant growth and physiology.
Plant growth and physiology. (A) Stem height was measured to the apical meristem. (B) Leaves longer than 2 cm were counted for leaf numbers. Error bars in panels A and B are standard errors from eight plants per condition at each point. (C) CO2 gas exchange rate at a PAR level of 400 µmol m−2 s−1 for control (ctrl) and copper (cu)-, drought (dr)-, and shade (sh)-treated plants. Error bars in panel C are 1 standard error of the mean (standard deviation/mean) from 10, 8, 10, and 9 (control, copper, drought, and shade, respectively) measurements across 3 days. (D) Photosynthesis rate for two drought plants (gray lines) and one control plant (black line) throughout a drought cycle. Watering events are indicated by vertical dotted lines.
