Abstract To examine several of the assumptions on which the procedure for predicting height growth in relation to age is based, stem analyses of five trees in each of ten 25-year-old slash pine plantations in Chester-field County, South Carolina, were studied. The analyses indicated that the relationship of the logarithm of height and the reciprocal of age is essentially linear between ages 10 and 25. Analysis of all stands showed no correlation between the height reciprocal of age relationships and actual site indices. There was room for speculation, however, concerning bias; dropping one plantation from the computation caused a high degree of correlation between actual site index and the slope of the height and age regression.
McGee et al. (Sat,) studied this question.
