What influence does acid rain have on seed germination?

Answered by admin @ 23/11/2021

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)
