Figure 3 Response of leaf photosynthetic rate to leaf
temperature for cotton plants grown under different temperature and
water regimes. Solid line indicates fitted photosynthesis-temperature
response curves using quadratic function and surrounding shaded bands
indicate the corresponding 95% confidence interval (n=5). Note that the
photosynthesis-temperature response curves for 32/22oC
and 32/26oC treatments are overlapped in panel a.
