Seedling insensitivity to ozone for three conifer species native to Great Smoky Mountains National Park
Neufeld HS, Lee EH, Renfro JR, Hacker WD. 2000. Seedling insensitivity to ozone for three conifer species native to Great Smoky Mountains National Park. Environmental Pollution. 108:141-151
Field symptoms typical of ozone injury have been observed on several conifer species in Great Smoky Mountains National Park, and tropospheric ozone levels in the Park can be high, suggesting that ozone may be causing growth impairment of these plants. The objective of this research was to test the ozone sensitivity of selected conifer species under controlled exposure conditions. Seedlings of three species of conifers, Table Mountain pine (Pinus pungens), Virginia pine (Pinus virginiana), and eastern hemlock (Tsuga canadensis), were exposed to various levels of ozone in open-top champers for one to three seasons in Great Smoky Mountains National Park in Tennessee, USA....
