Two alternative hypotheses can be used to explain how the embryo or embryonic axis controls food mobilization in seeds of many dicotyledonous plants. The first involves the production of a hormonal stimulus by the axis which initiates the development of optimal rates of hydrolytic enzyme activity in the storage organs. The second involves the continual operation of a source‐sink relationship between the storage organs (source) and axis (sink) during germination and early seedling development. The evidence for the operation of these modes of control is discussed.
