Synopsis

Anyone who observes fruit trees may wonder how or why they behave in specific ways. Some trees grow upright and some are more spreading in habit. Some produce many flowers and small immature fruit only to drop most of the fruit later on; others grow more on their sunny side than their shady side, etc. It is common to ascribe such behavior to the trees as a whole. That is the wrong approach to understanding tree functioning and behavior. Trees are not in control of what they do. The control of what trees do and how they function is in the individual organs that make up the tree, not in the tree as a whole. The genetic code only indirectly determines the habit, structure and behavior of a tree by defining the behavioral and functional limits of the organs, tissues and cells that make up the tree. Unlike animals that have a mechanism for collective control of the whole organism - a nervous system - trees (and plants in general) are more appropriately considered as collections of semi-autonomous organs that are dependent on one another for resources, such as water, energy (carbohydrates) and nutrients, but control their own destiny. The goal of this book is to present a clear set of integrative concepts for understanding the overall physiology of temperate deciduous fruit trees. The emphasis is on overarching principles rather than detailed descriptions of tree physiology or differences among the numerous species of fruit trees. Most of what is presented pertains mainly to temperate deciduous fruit trees but some aspects also apply to evergreen fruit trees and trees that grow naturally in the unmanaged situations. Highly relevant for students and researchers in pomology, horticulture and plant sciences, the book is also suitable for practitioners, extension, and novice tree fruit growers.
