ABSTRACT
Canopy temperature is an important factor of crop yield. How to test the canopy temperature for an effective prediction of crop yield is an important content of breeding research. In this study, the canopy temperature of winter wheat during their filling stage and mature stage were gained by infrared imager. Results demonstrated that the absolute canopy temperature and morning-noon temperature difference of the winter wheat are significantly negative correlated with the yield. During the filling stage, the yield (dry weight) showed a correlation coefficient (r) with the absolute canopy temperature in the morning of -0.63, -0.75 with the absolute canopy temperature at noon and -0.74 with the absolute canopy temperature in the afternoon. Meanwhile, the correlation coefficients between the yield (fresh weight) and above three absolute canopy temperatures were -0.59, -0.68 and -0.68, respectively. During the mature stage, the yield (dry weight) showed a correlation coefficient with morning-noon temperature difference of -0.76 and -0.56 with the morning-afternoon temperature difference and -0.54 with the noon-afternoon temperature difference. Meanwhile, the correlation coefficients between the yield (fresh weight) and above three temperature differences were -0.68, -0.58 and -0.40, respectively.
