“…The effects of acid rain on plants are growth reduction or stimulation, inhibition of seed germination and of nodulation and nitrogen fixation in leguminous plants, removal of the epicuticular wax and cuticle constituents, alterations in the gas exchanges, reduction in a and b chlorophyll contents and photosynthesis rates, increase in nutrient leaching (K, Ca, Mg, Na and Mn) from leaves, chlorosis and necrosis in the leaves and cell intoxication resulting from enzymatic disturbances (Kozlowski, 1980;Evans, 1984;Percy, 1986;Singh and Agrawal, 1996;Fan and Wang, 2000;Velikova et al, 2000;Singh et al, 2004).…”

Eugenia uniflora and Clusia hilariana seedlings were submitted to simulated acid rain, pH 3, for 40 days. The degree of visible injury and the anatomical and micromorphological alterations were determined 24 hours after the last simulation. E. uniflora presented a higher degree of leaf necrosis. The adaxial epidermis and part of the palisade parenchyma of the entire leaf blade were affected and hypertrophy, hyperplasia and cicatrization tissue differentiation occurred. Erosion and morphological modification of the epicuticular wax and alterations in the epidermis were detected on the upper and lower leaf surfaces. Stomata with deformed ostioles and rupture of the stomatal ledge were observed. C. hilariana presented necrosis in leaf margin and in abaxial leaf surface, showing collapsed cells or with plasmolized aspect, cicatrization tissue, epicuticular wax alterations, occasional leaf perforations, irregular arrangement of adaxial epidermis cells and twisted subsidiary cells. The structural alterations indicated a greater susceptibility of E. uniflora to acid rain. The lower sensibility of C. hilariana can be related with the anatomical characteristics as: thick cuticle with evident cuticular flanges, three layers of hypodermis and mesophyll more thick and compact.

“…Similar results found in tomato when treated by SAR treatment of pH 2.5 showed that the growth parameters including plant height, the number of leaves, shoot weight, and stem girth were reduced significantly (Debnath et al 2020). Singh and Agrawal (1996) conducted a field experiment on two cultivars of wheat (Triticum aestivum var. Malviya 206 and 234) to assess the effects of SAR of pH 5.6 (control), 5.0, 4.5, 4.0, and 3.0.…”

Due to its deleterious and large-scale effects on the ecosystem and long-range transboundary nature, acid rain has attracted the attention of scientists and policymakers. Acid rain (AR) is a prominent environmental issue that has emerged in the last hundred years. AR refers to any form of precipitation leading to a reduction in pH to less than 5.6. The prime reasons for AR formation encompass the occurrence of sulfur dioxide (SO 2 ), nitrogen oxides (NO x ), ozone (O 3 ), and organic acids in air produced by natural as well as anthropogenic activities. India, the top SO 2 emitter, also shows a continuous increase in NO 2 level responsible for AR formation. The plants being immobile unavoidably get exposed to AR which impacts the natural surrounding negatively. Plants get affected directly by AR due to reductions in growth, productivity, and yield by damaging photosynthetic mechanisms and reproductive organs or indirectly by affecting underground components such as soil and root system. Genes that play important role in plant defense under abiotic stress gets also modulated in response to acid rain. AR induces soil acidification, and disturbs the balance of carbon and nitrogen metabolism, litter properties, and microbial and enzymatic activities. This article overviews the factors contributing to AR, and outlines the past and present trends of rainwater pH across the world, and its effects on plants and soil systems.

“…A redução de biomassa na parte aérea e raízes também foi observada por Cohen et al (1981), ao analisar os efeitos da chuva ácida em plantas de cenoura e em beterraba, bem como por Singh et al (1996), que testaram dois cultivares de trigo. Em ambos estudos, observou-se redução signifi cativa de biomassa, tanto aérea quanto subterrânea, quando submetidos à chuva ácida.…”

RESUMOPlantas de Feijão (Phaseolus vulgaris (L.), cv. IPR88 Uirapuru, cultivadas em casa de vegetação, foram expostas à chuva ácida simulada (pH 3,0), obtida pela utilização de ácido sulfúrico, por dez dias consecutivos, vinte minutos por dia, com o objetivo de avaliar seus efeitos sobre os parâmetros morfológicos, de crescimento, a fenologia e os componentes de produção. As plantas foram comparadas ao tratamento controle (pH 6,0), durante os estádios V3 (primeira folha trifoliada), R6 (abertura da primeira fl or) e R7 (início da formação das vagens). Nas coletas parciais, foram avaliados a altura de planta, o diâmetro do caule, a matéria seca de parte aérea e raízes, a razão raiz/parte aérea. Ao fi nal do ciclo, analisou-se o número de vagens por planta, a altura da inserção da primeira vagem, o número de grãos por vagem o comprimento de vagem, e o peso de mil grãos. As plantas, sob condições de chuvas mais ácidas, sofreram mais a diminuição na sua altura da planta e revelaram leve aumento no diâmetro do caule, no estádio R7. Tiveram, também, menor produção da matéria seca da parte aérea e raízes no estádio R7, e uma redução signifi cativa da razão raiz/parte aérea, no estádio V3. No estádio R9, as plantas expostas à chuva ácida apresentaram redução do número de vagens por planta e aumento na altura de inserção de primeira vagem.
