Offers a broad perspective on C 4 grasses and the factors affecting their growth. These grasses, which include important crop plants, share a number of characteristics and are appropriately treated as a group. This book shows how growth patterns differ among genotypes and how these differences are responsible for variation in adaptation to particular environments. Early chapters provide a brief overview of important C 4 grasses covering their distinctive anatomy, physiology, taxonomy, and distribution, while later chapters describe normal growth and development and examine the effects of non-nutritional factors.
