摘　　要：对优质专用小麦“890 1 11 14”拔节期光合生理特性的观测分析结果表明 ,该小麦品种拔节期光合速率、蒸腾速率与CO2 吸收值有极显著相关性 ,而与光合有效辐射、CO2 初始浓度、气孔阻力等相关性相对较小。并建立了优质小麦“890 1 11 14”光合速率数值模型 ,经检验证明该模型可较好地表现拔节期优质专用小麦“890 1 11 14”The photosynthetic and physiological characteristics of high quality wheat “8901-11-14” at the jointing stage were studied in Huang-Huai-Hai Plain. The results show that the correlated efficiency of the photosynthetic rate and the transpiration rate, as well as that of the photosynthetic rate and the amount of absorbed carbon dioxide, are significantly correlated, while the other concerned factors, such as physiological active radiation(PAR), the initial concentration of carbon dioxide, and the stomatal conductance, only have a limited influence upon the photosynthetic rate in this time. The quantitative model of photosynthetic rate of high quality wheat“8901-11-14” is constructed, which can be proved suitable in expressing the dynamic day-change of photosynthesis rate at the jointing time.
