Abstract:

The specific objectives of this research are 1 to compare the stomatal frequency of two selected eastern white pine, one sensitive and one tolerant to O3 2 to characterize the fine structure of the epicuticular wax on needle surface and to compare the wax structure of the two selected clones 3 to continue the determination of the relative sensitivity of selected eastern white clones to NO2, SO2, and O3 used singly and in combination 4 to investigate photosynthetic and respiratory rates of different eastern white pine clones during light and dark conditions as influenced by NO2, SO2, and O3 and 5 to determine the influence of NO2, SO2, and O3 fumigation on needle chlorophyll content. A summary of the most important results is given and papers produced by the participants are listed.
