Technical Abstract: Fruit tree architecture is an increasingly important aspect of fruit production. Pomologists and fruit growers are looking to tree architecture as a way to address various production issues and increase profitability. Stone fruits, particularly peaches, have perhaps the widest range of described growth habits (weeping, dwarf, semi-dwarf and pillar) among the tree fruits, although to date they have been under-utilized commercially. This book does an excellent job of consolidating what is known about each stone fruit tree form in a single easy-to-read source. The general editor, Daniele Bassi, a well-known peach and apricot breeder at Milan University, has done extensive research on tree growth habits. Individual crop editors are also well-known: Rolando Guerriero (apricot), Gino Bassi (sweet cherry), Elvio Bellini (plum), and Alessandro Liverani (peach). For each growth type details are given on how to measure and characterize these trees based on twigs, branches and angles.
