Reduction of Growth and Symbiotic Nitrogen Fixation in Soybean as Affected by the Site of Simulated Acid Rain Application.

Impact of simulated acid rain on photochemistry, morphology, and yield of the wild blueberry (Vaccinium angustifolium Ait.)

“…Internal injuries may result in abnormal cell proliferation and enlargement, causing a reduction in leaf area in sensitive species (Evans and Curry 1979). Moreover, acid rain may decrease pigmentation and photosynthesis (Singh and Agrawal 1996;Wang et al 1997), resulting in reduced plant growth and yield. Foliage of herbaceous species such as Glycine max, Pteridium aquilinum, and Phaseolus vulgaris is very sensitive to acid rain (Evans and Curry 1979).…”

“…Damage to a plant from acid rain may cause a decrease in leaf area and photosynthesis (Singh and Agrawal 1996;Wang et al 1997). Results have shown that a single acid rain treatment (pH 1.8) to P. vulgaris can reduce gas exchange, the maximum carboxylating efficiency and photochemical quenching (Velikova et al 1999).…”
