摘要： Temperature is an important factor which significantly affects rice growth and development. In order to examine the effect of different temperatures at filling stage on grain protein synthesis and accumulation, present study with three different treatments day-night temperature dynamics was carried out in a randomized complete block design with five replications in Experimental Research Farm, College of Agriculture, South China Agricultural University, Guangzhou, China. Treatments included Te1: 33/27 degrees C, Te2: 28/22 degrees C, Te3: 23/17 degrees C under 1300X yellow light intensity and 75% humidity respectively. Result showed that Te2 and Te3 enhanced the activity of glutamic oxalacetic transaminase (GOT) and glutamic-pymvic transaminase (GPT) in grain in middle and later phase of filling stage while the soluble protein and crude protein in grain were higher in Te3 and Te2 compared with Te1. Furthermore, there were also some differences in activities of glutamine synthelase (GS), glutamate synthetase (GOGAT) and glutamate dehydrogenase (GDH) under different controlled temperature treatments while we observed that grain protein had significant correlation with the activities of GOT, GS and GDH. In general, we considered Te2 as the optimum conditions for rice at filling stage because it enhanced the grain protein content while having the highest yield. We also suggested that in the rice production, we could take some strategies such as delayed sowing date to appropriately lower the temperature at filling stage so the grain protein content could be improved.
