Impact of Heavy Glaze in a Loblolly Pine Spacing Trial
In March 1994, a severe ice storm badly damaged an 11-yr-old loblolly pine spacing study in central Virginia. After the storm, trees in the spacing trials were categorized into one of five stem and top damage classes. Analysis of variance procedures indicated no significant relationship between stem and top damage and spacing or density. Forked trees were found to be more susceptible to ice damage than single-stemmed trees. At an individual tree level, strong correlations were found between diameter and height and the type (stem bending or top breakage) and severity of damage. Prediction equations were developed for estimating the probability of five levels of stem bending and top breakage based on a proportional odds model. South. J. Appl. For. 20(3):151-155.
