一、引言本文从数量上分析小麦穗粒的物质来源,各绿色器官的贡献和彼此的关系,主茎和分蘖之间以及各器官之间的物质调配情况,并结合土壤湿度的影响看它们的变动,以期为进一步控制作物产量形成过程提供必要的基本资料.Archbold (1945)、殷宏章(1956)、武田(1956)等已经确定稻、麦的籽粒产量极大部分来 I. INTRODUCTION This paper analyzes quantitatively the material sources of wheat ear grains, the contribution of each green organ and their relationship to each other, the material distribution between the main stems and tillers and between various organs, and their impact on soil moisture With a view to providing the necessary basic information for further controlling the formation of crop yield.Archbold (1945), Yin Hongzhang (1956), Takeda (1956) and others have determined that the grain yield of rice and wheat has come largely
