Response of Stem Growth and Function to Air Pollution.

PB94209798

Publication Date	1994
Personal Author	Weber, J. A.; Grulke, N.
Page Count	38
Abstract	The exposure to air pollutants can result in reduced stem growth, changes in wood density, and/or deposition of pollutants in the stem. Several recent reviews summarize the known effects of air pollutants on plant growth and function including trees. Air pollutants many also change the defensive capacities of stems through alternation in chemical constituents. In this chapter, the authors review the literature on the effects of several major types of air pollutants on stem growth and function with the goals of better defining our knowledge in these areas and of suggesting areas in need of further investigation.
