The bearing habit of a species can be described by the location and types of buds which produce flower and fruit. Flower buds are borne laterally on shoots or spurs (Figure 11). Although green unripe fruit are photosynthetic, they require supplemental carbohydrates for proper development. In most fruit and nut tree crop species, the majority of carbohydrates required for fruit development are acquired from two sources: 1) reserves stored from the previous growth season in adjacent branch tissue, and 2) photosynthesis throughout the growing season in nearby leaves.
Each fruit and nut crop species has a distinct bearing habit and growth form. Flower buds are formed laterally on woody tissue, terminally at shoot tips, or on spurs. The Summary Table lists the bearing habit of 18 fruit and nut tree crops commonly grown in California.
