Growth Patterns Of Different Fruit Sigmoid Growth Pattern

Different fruit grow in different ways, although there are a few general patterns of fruit growth. One common pattern is the "sigmoid" form of growth in which the fruit begins to grow slowly initially after bloom but then grows increasingly rapidly (see diameter curve in Figure F3.2). The growth rate is the greatest in midseason, followed by a slowing growth as harvest approaches. This type of growth pattern means that the growth rate in weight gain per day is low early and late in the season and greatest in midseason. Apples and pears often show a seasonal growth pattern that at first appears to be sigmoid due to a slowing of growth in cooler temperatures near harvest, although there is normally an extended linear portion of growth in midseason.
