摘　　要：为探明国审棉花新品种冀丰103高产、广适的生理特性,对其不同生育时期的光合速率、叶面积指数、叶绿素含量和可溶性糖含量,以及产量等性状指标进行了测定与分析。结果表明:冀丰103在初花期至盛花期光合速率高且一天当中高光合速率时间长,盛花期至吐絮期可溶性糖含量高,盛铃期至吐絮期叶面积指数大、叶绿素含量高。冀丰103在生长发育旺盛时期光合速率高,有助于制造更多的光合产物;在发育后期叶面积指数和叶绿素含量高,是有效延长叶片光合活力和制造光合产物时间,从而形成较高产量的内在生理基础。In order to explore the physiological characteristics of high yield and wide adaptability of Jifeng 103,a new national authorized cotton variety,the photosynthetic rate,leaf area index,chlorophyll content,soluble sugar content and yield at different growth stages were measured and analyzed.The results showed that the photo-synthetic rate of Jifeng 103 was high from initial flowering stage to full flowering stage,and the time of high photosynthetic rate was long in a day.The content of soluble sugar was high from full flowering stage to boll opening stage,and the leaf area index and chlorophyll content were high from full boll stage to boll opening stage.Jifeng 103 has high photosynthetic rate during vigorous growth and development,which is helpful to pro-duce more photosynthetic products.At the later stage of development,the high leaf area index and chlorophyll content are the internal physiological basis for effectively prolonging the photosynthetic activity of leaves and the time of producing photosynthetic products,so as to form a higher yield.
