Physically bending a branch of an apple tree results in a reduction in terminal shoot growth and redistribution of growth hormones, particularly auxin. The effect on growth reduction and increase in (spurs) flower initiation caused by bending occur only during the season when the physical bending stress is imposed or the limb orientation is changed (This video). This effect has commercial value, since, by progressively changing branch orientation by inserting a longer spreader each year, a growth reduction can be achieved for several years.
