This new edition of an established title examines the determination of grain crop yield from a unique perspective-- by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself, determine the yield of grain crops....
