Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

Resource Type:: Dissertation
Full Text:: leaves. 49 IV.l. The effects of ozone (0.12 ul 1-1) on growth of radish (Raphanus sativus) and soybean

The economic effects of ozone on U.S. agriculture : a sector modeling approach

Creator:: Hamilton, Scott A.
Abstract:: Tropospheric ozone is a pollutant which has detrimental effects on crop yields. The level of ambient ozone can be reduced by environmental policy changes and enforcement. The purpose of this study was to estimate the welfare effects of such changes in ambient ozone using recently available plant response data and...

Monitoring for Ozone Injury in West Coast (Oregon, Washington, California) Forests in 1998

Creator:: Campbell, Sally J., Smith, Gretchen, Temple, Pat, Pronos, John, Rochefort, Regina, and Andersen, Chris
Abstract:: In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive...

Individual and population responses to abiotic stresses in Italian ryegrass (Lolium multiflorum Lam.)

Creator:: Martinez-Ghersa, Maria Alejandra
Abstract:: Plant form is a compromise between resource gathering, reproduction and the tolerance to physical demands of the abiotic and biotic environment. In an agricultural field in addition to the natural factors causing stress, humans also introduce physical and mechanical stresses, and chemical pesticides into the environment. Many of these factors...
Resource Type:: Dissertation
Full Text:: of three anthropogenic stresses (herbicide, UVB light and ozone) and their interactions on

Effects of single and multiple stressors on communities of wheat and wild oats

Creator:: Pfleeger, Thomas G.
Abstract:: Most plant toxicology tests developed in support of environmental laws use a single stress applied to an individual plant. While tests using individual species or stresses require fewer resources and are easier to interpret, they are under increasing criticism for being unrealistic and missing important ecological interactions. The objective of...
