Effects Of Temperature

In this study, we investigated the effects of temperature frequency trends on the projected yield and dry matter distribution of japonica rice (Oryza sativa L.) with elevated carbon dioxide (CO2) under future climate change scenarios in northwestern China. The Crop Environment Resource Synthesis (CERES)-Rice model was forced with the outputs from three general circulation models (GCMs) to project the rice growth and yield. Future temperature trends had the most significant impact on rice growth, and the frequency of higher than optimal temperatures (∼24–28 oC) for rice growth showed a marked increase in the future, which greatly restricted photosynthesis. The frequency of extreme temperatures (>35 oC) also increased, exerting a strong impact on rice fertilization and producing a significantly reduced yield. Although the increased temperature suppressed photosynthetic production, the elevated CO2 stimulated this production; therefore, the net result was determined by the dominant process. The aboveground biomass at harvest trended downward when temperature became the major factor in photosynthetic production and trended upward when CO2-fertilization dominated the process. The trends for the leaf and stem dry matter at harvest were affected not only by changes in photosynthesis but also by the dry matter distribution to the panicles. The trends for the rice panicle dry matter at harvest were closely related to the effects of temperature and CO2 on photosynthetic production, and extreme temperatures also remarkably affected these trends by reducing the number of fertilized spikelets. The trends of rice yield were very similar to those of panicle dry matter because the panicle dry matter is mostly composed of grain weight (yield). This study provides a better understanding of the japonica rice processes, particularly under extreme climate scenarios, which will likely become more frequent in the future.

This thesis has listed rice as the research object, and by way of water treatment (water-saving treatment and CK treatment) and nitrogen-fertilizer treatment (N0, N1, N2, N3, N4), to analyze the effects of water and nitrogen fertilizer coupling on the yield and panicle architecture of rice. Results show that compared with CK, water-saving irrigation is more effective in promoting the yield. Under N-fertilizer treatment of N1, N2 and N3, the rice yield was increased by more than 10%; while under N0 and N4, the yield difference was not significant. With the increased apply of Nitrogen, under the two watering means, the yield both showed a tendency of firstly increase and later decrease. The yield hit the highest point in water-saving irrigation under N3, followed by water-saving irrigation under N2, and CK under N3.Under N2 and N3, the yield increased in water-saving irrigation was mainly contributed by the increase of the second rachis branches. The yield was increased by 30.69% and 30.37% under N2 and N3 separately. With water-saving irrigation, the yield under N3 is more than that under N2, this is mainly contributed by the increase of the grain number per panicle and the thousand seed weight. Under N3, the yield difference was not significant in either watering treatments, but water-saving irrigation has increased the average value of yield traits. Analysis of the panicle architecture has revealed that compared with CK, water-saving irrigation is more effective in increase the rice yield, which was mainly realized by the significant increase in the number of second rachis branches.

In order to determine the effects of nitrogen fertilizer on the grain quality and starch physicochemical properties of japonica rice cultivars with different contents of amylose, normal amylose content (NAC) and low amylose content (LAC) cultivars were grown in a field, with or without nitrogen fertilizer (WN). The relationships between the amylose content, starch physicochemical properties and eating quality were also examined. Compared with WN, nitrogen fertilizer (NF) significantly increased the grain yield but markedly decreased the grain weight. In addition, the processing quality tended to improve, but the appearance quality and eating quality deteriorated under NF application. The grain yield was similar between NAC and LAC cultivars. However, the grain quality and starch physicochemical properties were significantly different between NAC and LAC cultivars. The palatability of the cooked rice was significantly higher in the LAC than in NAC cultivar, which was due to its lower amylose content, protein content, hardness, and retrogradation enthalpy and degree, and its higher stickiness, peak viscosity, breakdown, relative crystallinity and peak intensity. The amylose content and protein content were significantly negatively correlated with the palatability. The amylose content was significantly positively correlated with the final viscosity and setback, and was significantly negatively correlated with the relative crystallinity, peak intensity, gelatinization enthalpy and breakdown. Palatability was significantly positively correlated with peak viscosity, breakdown and peak intensity, and was significantly negatively correlated with the final viscosity, setback, and retrogradation enthalpy and degree. Therefore, the selection of a low amylose content japonica rice cultivar grown without nitrogen fertilizer can reduce the amylose and protein contents, as well as improving the pasting properties, starch retrogradation properties and eating quality of the cooked rice.
