Monitoring of Shoot Development The growth of 18 four-year old cedars was charted monthly for six months (June to November 1991). On each chart, the tree's top 40-50 cm was drawn in a line sketch in which all laterals and buds were recorded (Figure 2). Also recorded for each tree were two height measurements: the height from the ground to the tallest part of the tree, which was determined by orienting all upper branches vertically; and the height from the ground to the tallest part of the terminal lead- er, which was originally located using Parker and. Johnston's (1987) method of counting stem leaf pairs and confumed in the second and subsequent observa- tions. 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..
