A field experiment was conducted to illuminate the daily variation of canopy temperature and its relationship with soil water content, physiological characteristics and grain quality with Liaojing 294 and Kaijing 1 as materials during filling stage at five gradient soil water contents.The results showed that: 1) The canopy temperature, lower than air temperature, was significantly positively correlated with air temperature. The gradient soil water stress led to a gradual increase in the canopy temperature and canopy-air temperature difference. That is to say, the canopy temperature and the absolute value of the canopy-air temperature difference increased as the soil water potential declined. 2) Under the same conditions, the canopy temperature of drought susceptive variety Liaojing 294 was lower than that of the drought resistant variety Kaijing 1. 3) The canopy-air temperature difference was significantly negatively correlated with filled grain number per panicle, 1000-grain weight, seed-setting rate, grain yield, percentage of head rice, protein content, amylase content, fatty acid content and taste value. But it was significantly positivel correlated with unfilled grain number, chalkiness degree, chalkiness rate and broken rice rate. 4) As the soil water potential decreased, the photosynthetic rate, stomatal conductance and transpiration rate decreased, and photosynthetic performance of the drought resistant Kaijing 1 was better. Correlation analysis showed that there was a significant or extremely significant negative correlation between the photosynthetic performance and the canopy-air temperature difference. 5)For Kaijing 1, the stomatal density was significantly greater than that of Liaojing 294, and the stomatal length and width were extremely significantly less than Liaojing 294. Comprehensive analysis showed that there was no significant impact on grain yield compare with control with canopy-air temperature differernce of 0.9 ℃ and 0.8 ℃ for Liaojing 294 and Kaijing 1, respectively. The critical water content could be used as a rice water-saving threshold at the filling stage (soil water potential treatment S2, -0.02--0.03 MP).
