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).
How does acidity affect germination?
High pH negatively affected the germination rate of seeds from most species, but had no effect on the per cent germination of any of the species. The higher concentration of the nutritious solutions affected negatively the germination level and rate. … These differences in germination are species dependent.
How does acid rain affect crop?
Plants and crops: Acid rain can potentially reduce agricultural production by changing the chemical properties of soil, slowing the rate of microbiological processes, and reducing soil nutrients. Roots of natural vegetation and crops can become damaged due to stunted growth.
Does acid rain stunt plant growth?
Acid rain generally retards the growth of plants by stimulating abnormalities in metabolism of the plants, like photosynthesis, nitrogen and sulphur metabolism, however, there are exceptional cases of promoting growth as well.
What is the effect of acid on the seed germination of green bean seed?
QUESTION: How does acid rain affect the germination and growth of green bean seeds? HYPOTHESIS: From our research we found out that acid rain has a pH of approximately 5.6. Therefore we think that some of the bean seeds will be able to germinate with water at a pH level of 5, but will sprout and grow at a slower rate.
Does acidity affect plant growth?
Acidity has the following effects on soil: It decreases the availability of plant nutrients, such as phosphorus and molybdenum, and increases the availability of some elements to toxic levels, particularly aluminium and manganese. Essential plant nutrients can also be leached below the rooting zone.
Does the pH of acid rain affect the germination of seeds?
Rice, wheat and rape seeds were treated with simulated acid rain at pH 2.0, 2.5, 3.0, 3.5, 4.0 and 5.0 levels for 7 days in order to understand the effects of acid rain on seed germination of various acid-fast plant. The germination test showed that seed germination was absolutely inhibited at pH 2.0 for three species.
What are 3 effects of acid rain?
Acid rain has been shown to have adverse impacts on forests, freshwaters, and soils, killing insect and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.
Where is acid rain a major problem?
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
What is acid rain write its effect?
When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish. The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives.
What is acid rain describe its effect in 150 words?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Can acid rain kill you?
Can acid rain kill you? While acid rain can be incredibly detrimental for the environment and will kill many plants and animals over a long enough exposure, it won’t directly hurt or kill you.
How do you counteract acid rain?
A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
