Offers a clear, detailed treatment of the principles of fruit growing from the standpoint of whole-tree physiology. This unique text supports all observations with analytical data and demonstrates them through extensive illustrations and color plates. Points out variations of several commonly stated horticultural phenomena (e.g., those species which take more than 50 days to bloom, those in which flower differentiation does not take place in the summer, etc.). After an examination of the ontogeny and morphology of buds, shoots, roots, flowers, and fruits, it covers current pomology practices and describes the features and horticultural requirements of numerous species that are grown in the temperate fruit-growing areas around the world. Also includes interesting information on the origins and history of various species.
