Abstract
High temperature negatively impacts rice production, and the heat-tolerant cultivars could improve the resistance to high temperature stress. In the present study, six rice varieties were exposed to high temperatures stress (35C and 38C) for 3 days during the early filling stage. The differences among two high-temperature treatments were analyzed in terms of yield components, grain quality and physiological parameters of rice. The results showed that high temperature decreased seed setting rate, 1000-grain weight, plumpness, single plant yield, brown rice rate, milled rice rate and amylose content while increased unfilled grain rate of all rice varieties compared with the control. However, the yield components of different rice varieties in response to high temperature exhibited significant genotypic differences. In addition, the influence of high temperature on the hybrid rice variety Jinyou402 was greater than that on Ganxin203, and the influence of high temperature on the conventional rice variety E134 was greater than that on Zhong531. The 38C treatment was more damaging to early rice than the 35C treatment. Meanwhile, the influences of high temperature on the physiological parameters of flag leaves were consistent with the influence on yield components and grain quality.
