The incidence and severity of Heterobasidion annosus (Fr.) Bref. in loblolly pine plantations and the effect on radial increment growth
… of the root system (healthy). The average annual increment for each of the last five years was tested, and all five tests were significantly different in growth at the 0.01 level. The difference in growth between healthy and diseased trees over the five year period was 19% or approximately 4% per …

Growth loss of loblolly pine (Pinus taeda L.), white pine (P. strobus L.) and sycamore (Platanus occidentalis L.) proximal to a periodic source of air pollution
… on the growth of forest trees was investigated. Radial increment growth studies were conducted to determine if correlations existed between emission levels of a source (predicted by production levels) and radial increment growth of forest trees. Three stands of loblolly pine, two of white pine, …

The incidence and severity of Heterobasidion annosum (Fr.) Bref. in loblolly pine (Pinus taeda L.) unthinned plantations and seed orchards
… trees exhibited conks on high hazard sites. Mean radial increment growth differences between H. annosumcolonized and noncolonized trees were analyzed using the Duncan's Multiple Range test and for the 10-year period prior to excavation no significant growth reduction was observed. Due to low …
