Light response curves of APH canopy photosynthesis: The APH CQY, the slope of gross photosynthesis vs. absorbed PPFD, represents the photosynthetic conversion of absorbed radiation into fixed CO2. The CQY of the wheat/Arabidopsis canopy measured in APH (WRB LEDs, purple open circles) is higher than reported in BPS 2002 (CWF lamps, black squares), but comparable to literature values of wheat CQY: Wheeler, 1996 (HPS lamps, red diamonds), and Monje and Bugbee, 1998 (HPS lamps, blue triangle).
