Answer:
Acid rain is an umbrella term, which is used
to cover a number of different pollution
processes. The pH of acid rain is ten, fold
difference between numbers. India illustrates
the drastic effect of acid rain on agricultural
productivity researchers there found that
wheat growing near a coal fired power plant
where SO2 deposition was almost five times
greater than the critical load (the amount of
the soil can safely absorb without harm)
suffered a 49% reduction in yield. In the
present investigation to assess the effect of
acid rain on the plant growth, the plant of
Triticum aestivum and Raphanus sativus
were grown in different wooden boxes and
three different plastic boxes. The different pH
(2.0, 4.0, 5.0) of simulated rain does were
sprayed on the plant and after last dose the
specific visual difference was seen in seed
germination. increased acidic level (pH 2.0) of the rain water affects the seed germination by the rate of 40% as compared to that of lower level of acidity (pH 4.0 and 5.0)
