Wood Properties of Pinus Radiata Infected With Dothistroma Pini
Year: 1978
Type: article
Abstract: Wood properties were measured on 10 nine-year-old trees from each of the four spraying treatments (aqueous solutions of copper-based fungicides) applied to control Dothisfroma pini infection of radiata pine in Sample Plot R919, Kaingaroa Forest. Wood samples were cut from levels in the stems corresponding to seven and four annual growth layers, and these were examined for wood density, shrinkage, green moisture content, growth rate, tracheid length, grain angle, resin content, pith diameter and bark thickness. Significant differences in wood properties that could be related to the spray treatments were limited to some loss of diameter growth in unsprayed, heavily defoliated trees (more apparent in the upper than in the lower stem), and also a trend to increasing wood density in outer growth layers following severe defoliation.
