The response of diameter and height of unthinned planted stands ofloblolly (Pinus taeda L.) and slash (Pinus elliottii Eng elm.)pine in East Texas to different classes of planting densities were analyzed. After tracking the development ofdiameterand heightfor 15yron a setofpennanentplots representing a broad range of plantation parameters, average diameter and average height trends were observed. For both species, average diameter values were significantly larger with lower planting densities. 1n contrast, average height growth is insensitive to planting density at younger age classes for loblolly and at older age classes for slash pine plantations.
