Abstract

In order to assess the degree of damage that acid rain has or might have on plants, experiments were performed to determine the change in seed yield of two agronomic crops, soybeans and pinto beans, after exposure to simulated rain of pH 5.7, 3.1, 2.9, 2.7, and 2.5. Moreover, the effects of simulated acid rain were determined on a variety of other experimental parameters to understand further how plants respond to this environmental stress. Simulated acid rain of pH 3.1 and below decreased the dry mass of seeds, leaves, and stems of pinto beans. On a percentage mass basis the decrease in seed yield was comparable to reductions in biomass of leaves and stems. The decrease in yield of pinto beans by simulated acid rain was attributed to both a (1) decrease in the number of pods per plant and (2) a decrease in the number of seeds per pod. In soybeans, simulated acid rain decreased the dry mass of both stems and leaves. Seed yield also decreased after treatment with rain of pH 2.5. However an increase in seed yield occurred when plants were exposed to rain of pH 3.1. A larger dry mass per seed was responsible formore » the larger dry mass of seed per plant.« less

Yield Responses of Field-Grown Soybeans Exposed to Simulated Acid Rain

Conference Evans, L. S. ; Conway, C. A. ; Lewin, K. F.

An important area of interest is to determine the effects of acid precipitation on the yield of agronomic crops under field conditions. Experiments described herein were performed with field-grown soybeans at Brookhaven National Laboratory during the summer of 1979. A preliminary experiment was performed the preceding year at the same site to estimate the most appropriate plot design and statistical analyses. Soybeans were seeded to provide six Latin Squares. Five treatments (no rain, simulated rainfalls of pH levels of 4.0, 3.1, 2.7, and 2.3) replicated five times in each Latin Square were used to produce a total of 30 plotsmore »« less

Comparison of yields of several cultivars of field-grown soybeans exposed to simulated acidic rainfalls

Conference Evans, L S ; Lewin, K F ; Hendrey, G R

Rainfall acidity-response functions for crop yield and growth are necessary to predict the overall impacts of crop yields of ambient and/or anticipated levels of acidic rain. The experiment described herein was performed at Brookhaven National Laboratory to determine the effects of simulated rainfalls of pH 5.6, 4.4, 4.1, and 3.3 on seed-yields of four cultivars of field-grown soybeams. Soybeans were chosen because previous results suggested that this crop is sensitive to rainfall acidity and because they are economically important. Sixteen plots per treatment were used. This level of replication has been shown to be recommended in order to detect differencesmore »« less
Comparison of experimental designs to determine effects of acidic precipitation on field-grown soybeans

Conference Evans, L S ; Lewin, K F ; Patti, M J ; ...

Two experiments were performed to determine changes in seed yields of soybeans grown under standard agronomic practices exposed to simulated acidic rain during the summer of 1981. Seed yields of soybeans exposed twice weekly to simulated rainfalls of pH 4.1, 3.3, and 2.7 were decreased 10.7, 16.8, and 22.9%, respectively, compared with plants exposed to simulated rainfalls of pH 5.6. A treatment-response function of seed yield versus rainfall pH was y = 7.40 + 1.025 x and had a correlation coefficient of 0.997. In a second experiment, soybean plants were not shielded from ambient rainfalls (weighted mean hydrogen ion concentrationmore »« less
Productivity of field-grown soybeans exposed to acid rain and sulfur dioxide alone and in combination

Journal Article Irving, P M ; Miller, J E - J. Environ. Qual.; (United States)

Sulfur dioxide (SO/sub 2/)-fumigated and unfumigated field plots of soybeans (Glycine max cv. Wells) were exposed to acid (pH 3.1) or control (pH approx. =5.3) precipitation simulants to determine effects on growth and productivity. The precipitation simulants were applied at approximately 5-day intervals in July and August with a total of 3.4 cm applied in 1977 and 4.5 cm in 1978. Sulfur dioxide fumigations of approx. =4-hour durations were performed 24 times in 1977 and 17 times in 1978, resulting in an average fumigation concentration of 0.79 ppm (89.6 ppmin equilibriumhour dose) SO/sub 2/ the 1st year and 0.19 ppmmore »« less
