| Summary: | Western gall rust infections of lodgepole pine decrease with height and age. These factors were separated in a study in which 327 trees of different ages in two height classes were inoculated in five replicates. Physiological characteristics were then monitored. As tree age increased between 2-10 years, the percentages of infected trees increased by 85% and the number of galls per 10 cm of shoot length increased by 88%. This suggests that early and aggressive precommercial thinning is not advisable in areas where gall rust is common. |
