Fig. 4. The association between leaf water content (g/g DW) and (A) stomatal
conductance, (B) transpiration rate, (C) internal CO2 concentration and (D) rate
of net photosynthesis of leaves of Chinese kale (full symbols) and Caisin (open
symbols) on plants that were either waterlogged (WL), droughted (WS) or wellwatered
(WW). Measurements were made 5, 7 and 11 days after treatments
began and the sequence of symbols from right to left represents these times.
