The charts were compiled each month for each of the 18 trees. It became obvious after the second month which resting buds were on branches and which resting bud was the true terminal; observations over the following months confumed these determinations. These six months of observations resulted in a rapid and accurate method for locating the terminal bud.. Figure 3.
