Acrotonia

from Wikipedia, the free encyclopedia

As Akrotonie means the promotion of buds size and the runner length at the tips of annual shoots. The size of lower-lying side buds or those formed near the annual base of the shoot remains, or the buds do not sprout at all. Thus, acrotonia leads to increased shoot and leaf formation in the outer crown area, in the faint crown interior the branching intensity is reduced. Acrotonia is typical of the growth of trees and is a cause of the storied structure of most conifers . In the case of inflorescences , acrotonia means the promotion of the terminal bloom and the upper side branches. Basitonia , the promotion of the buds in the basal area, is typical for shrubs .

The term acrotonia was first introduced by Karl Göbel in 1928 to promote leaf growth in the upper part, and later he also used it for inflorescences.
