ABSTRACT
USE OF INTERMODAL LENGTH IN THE GROWTH STUDIES OF CHIR PINE (PINUS ROXBURGHII)
R. W. Hussain and M. A. Cheema, Pakistan Forest Institute, Peshawar
Intro:
Increment borings (diameter) and internodal growth (height) arc being made use of in growth prediction studies and in the construction of the yield tables using calculus and regression techniques (2, 5). Curtis (2) estimated the rate of height growth i.e. through regression techniques by measuring each of the last six internodal lengths by grouping them into diameter classes. He subsequently utilized it in obtaining the current rate of volume growth in the preparation of yield tables of Douglas fir.
