| Abstract/Contents: | Reports on a "project sponsored jointly by the California Institute of Technology, the University of California, and the Los Angeles County Air Pollution Control District...[to compare] plants grown in air containing smog, and those grown in the same conditions in pure air." States that "Poa annua was grown in various combinations of day and night temperature, photoperiod, and light intensity in the Earhart Laboratory at intervals of approximately 6 weeks throughout the year. At the age of 4 weeks the plants were taken out and exposed to smog in standard test boxes." Concludes that "the environmental conditions under which Poa annua is grown strongly affect its sensitivity to smog." Explains that "smog sensitivity was not correlated with the size of plants, nor with the growth rate. It was also correlated to a high degree with the area over which the stomates were wholly or party open. It was correlated with oxidant levels, in data obtained when duration of maximal oxidant readings and climatic conditions were comparable." |
