摘要: 南京地区丰产小麦的叶色在返青、拔节、孕穗阶段显现“青、黄、青”节奏变化。返青阶段叶片正常显“青”,植株体内有适当高的氮素水平,有利于小穗、小花发育,成长大穗;拔节阶段正常显“黄”,叶、鞘、茎生长协调,有利于茎节发育及壮秆形成;孕穗阶段叶色转“青”,有利物质运转,籽粒灌浆顺利,不实小穗减少,增粒、增重。在壮苗基

Abstract: The results obtained from the experiments on the leaf-color shift in relation to the forma-tion of high yield of wheat in Nanking during 1961 and 1962 are summarized as follows:1.The leaf-color shift of wheat plant is an inherited biological character.The highyield is closely connected with these rh
