Flag leaf area (A), green leaf area (B), flag leaf chlorophyll a and b concentration (C) and flag leaf photosynthesis rate (D) at anthesis during the 2007–2008 and 2008–2009 growing seasons in the CK, AW, DW and NW plots.
The data are not available for the growing season of 2006–2007 since they were not determined in the first year. Values are means ±1 SE. Values followed by a different letter are significantly different (P<0.05).
