From the preceding lectures we have learned a great deal about how external conditions may influence various internal physiological processes within plants, and it therefore appears appropriate to consider briefly how these processes influence one another and also the manner in which they relate to yield. The main processes of interest in this connection are photosynthesis, respiration, and carbon assimilate translocation; but aspects of growth, development, mineral nutrition, etc., will also be considered when relevant.
