Time course of leaf gas exchange in sugarcane propagules under water deficit.

Leaf CO2 assimilation (A), stomatal conductance (B), and instantaneous carboxylation efficiency (C) in sugarcane plants grown under well-watered conditions (W/W and D/W) or subjected to water deficit (W/D and D/D). The propagules were obtained from plants previously exposed to water deficit (D/W and D/D) or grown under well-watered conditions (W/W and W/D). The gray area indicates the water deficit period. Each symbol is the mean value ± s.d. (n = 4).
