Height-Growth Patterns and Site Index of White Pine in the Southern Appalachians
Recently devised methods of developing site-index curves are used to investigate patterns of height growth in eastern white pine (Pinus strobus L.) and the impact of these patterns on estimation of site index. An exponential growth model is fitted to sets of height-growth data obtained by internode measurement. Estimated parameters of the growth function are then used to analyze the pattern of growth and some factors which affect it. Pattern of height growth of dominant and codominant trees varies significantly within even-aged stands but is not related to present density of the surrounding stand. Highly significant differences in the growth curve and its parameters are associated with the quality of the site, per se. Pattern of growth also varies to some extent at a given level of site index and is related to some topographic features of the site. Forest Sci. 17:252-260.
