Dormancy and bud break in warm climates; considerations of growth regulator involvement

Dormancy and bud break in warm climates; considerations of growth regulator involvement

The dormancy of the resting buds of trees is governed by environmental factors affecting the level of regulating substances which, in turn, control the metabolic changes leading to the onset of, or release from, dormancy.
