The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.
