The purpose of this supplement is to present detailed information which was not included in the actual thesis, but which is of special interest to subsequent investigators. It contains:
1) a sample data sheet showing the kind of stem and branch analysis data required for complete analysis of each tree.
2) coding requirements for computer analysis of the data
3) complete listings of original programs developed for analysis of growth responses in released trees:
a) Watfiv Programs
1. RADIAL, for radial growth response
2. HEIGHT, for height growth response
3. BRANCHES, for branch elongation response
b) CalComp programs:
1. RADVSAGE, to graph radius vs' age
2. HTVSAGE, to graPh height vs' age
3. PROFILE, to graph stem profiles (height vs radius)
4) a four-page package for each of 51 red spruce, 27 balsam fir, 18 black spruce and 4 white spruce (one fir and all white spruce were dropped from statistical analysis but are included in the supplement):
First page: output of program RADIAL. Radial growth responses five years and N years (period of release) before and after release are compared. The B.A. INC represents the baSal area "donut" laid on by a tree during a certain period. For periods of equal length before and after release from competition, the post release B.A. INC is compared to the pre- release B.A. INC, and a percent difference (% DIFF) is calculated' This was done at all meter, sections that were o1d enough to have periods of comparison.
Second Page: Computer generated graphs from programs RADSAGE, HTVSAGE, and PROFILE.
Third Page: output of program HEIGHT. Height growth response is calculated as the percent difference between the height increment after release and the height increment before release. The variable N represents the period of release.
Fourth Page: output of program BRANCHES. Branch elongation response for each of four sample branches is shown. Branch 1 was taken at the base of the live crown (BLC). The live crown ratio is calculated for 1978, the year of the sample.
Note: Trees are organized by species and by increasing radius at release (RADATREL) at one meter above the ground. Trees of equal RADATREL are ordered by increasing height at release (HTATREL).
