The large number of recent publications on the physiology of plant development reflects a widespread, contemporary interest in this subject. Researches in this area deal chiefly with the effects of specific growth substances and mineral nutrients on functional and structural ontogeny. The major contributions on the physiology of growth substances have already been conveniently assembled in certain excellent monographs (36, 53, 283, 339, 424) and reviews (37, 422, 192). Recent researches on nutrition in relation to plant development have not as yet been comprehensively reviewed. Data in this field as a whole are extremely diverse, especially as they relate to the nutritional cycle of biennial and perennial crops (20, 259, 411). In typical annuals, however, certain common relationships seem to characterize the mineral, carbohydrate and protein metabolism such that a number of
