A Plant Bioindicator System for Estimating Pollution Abatement - Elucidation of the Ultrastructural, Physiological, and Biochemical Basis of Sensitive and Tolerance to NO2, SO2, and O3.
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.
