Description
Understanding the ways in which apples grow and develop is crucial for achieving sustainable apple cultivation, which means a regulated crop of apples that provides as high a yield as possible of desired quality while allowing the development of a good and consistent return bloom and cropping in subsequent years. This chapter examines how apples grow and ripen (basic structure, growth habit and physiology), some of the factors that support or limit growth, why fruit abscise and how growers can manipulate fruit growth and abscission to optimize cropping. Among other topics, the chapter explores in detail seasonal growth patterns, the chemical composition of apples in different seasons, the role of hormones in abscission and seasonal ripening patterns. The chapter suggests ways to model and prevent apple thinning, and suggests future trends for research in this area
