Abstract: Increasing red light proportion had some effects to increase Leaf area,but made the specific leaf weight lower and the leaf thiner. Red light could decrease the content of chlorophyll,make the leaf colour lighter,increase the invertase activity,net photosynthetic rate,total carboi content,redu
