英文摘要为揭示大气中二氧化碳浓度与温度增高对水稻生长发育与产量形成的影响机理,采用半开放式二氧化碳温度梯度系统对水稻全生育期进行梯度处理。研究表明,550μmol/mol CO2浓度及温度升高1.5℃、650μmol/mol CO2浓度及温度升高2.0℃处理提高了水稻叶片叶绿素含量,灌浆期比对照(400μmol/mol及自然温度下)分别增加13.41%~16.74%,但对叶绿素a/b的比值影响较小;可溶性糖含量从拔节期开始随CO2浓度及温度增加而升高。增幅为6.06%~14.82%;可溶性蛋白含量总体上各处理结果均低干对照;脯氨酸含量在生育前期高干对照,在抽穗期趋干相同,在灌浆前期明显低干对照。表明CO2浓度与温度增高改变了水稻生理性状,改变了水稻生长对物质和能量需求平衡,延长了生育期,此点为导致水稻产量形成的最终变化提供了理论证据和支持。; To unveil the mechanism of effect of elevated CO2 concentration and temperature increasing on growth, development and yield formation of rice, many physiological characteristics of rice were measured from the half-open CO2- temprature gradient system, which treated whole growth duration of rice by different CO2 concentrations and temperature levels. The result shows as, 550 μmol/mol CO2 and 1.5℃ temperature increasing,650μmol/mol CO2 and 2.0℃ temperature increasing treatments increase chlorophyll contents of leaves to 13.41%-16.74% than CK(400μmol/mol CO2 and ambient temperature), especially during latter stages, but not changed rate of chlorophyll a/b. Soluble sugar content of treatments increase 6.06 % - 14.82 % than CK since jointing stage. Sotuble protein content of treatments is lower than CK. Dissociate proline content of treatments is higher CK in early stage, is close to CK at earing stage, and is lower than CK at early filling stage. The result indicates that elevated CO2 concentration and temperature increasing has changed physiological characteristics of rice, also changed the demand of matter and energy of rice growth, and delayed arowth duration. These chanaes affected vields formation process of rice.
