Abstract
IT has been reported that spraying spur-shoots of apricot with gibberellin stimulates cambial activity and leads to increased xylem development1. On the other hand, it is well known that indole-acetic acid stimulates cambial activity2. These observations raise the question as to what are the relative roles of this acid and native gibberellins in normal cambial activity. This problem has been investigated in the following experiments.
