Ecology of Organisms - Lab Report ExampleDifferent pH levels affected the germination and growth rates of the radish seeds. This test was examining the effects of different pH level on germination of radish seeds. Water with a pH of 6, vinegar pH 3 and baking seltzer pH 10.5 were used. From the results, pH 3 radish never grew at a slow rate radish on pH 10.5 grew at a poky fairly rate and pH 6.5 grew the fastest. In vinegar, only 10% of the seeds germinated 40% in baking soda and 100% in water. Extremely low pH affected seed germination and maximum growth recorded at a neutral pH. In general, the lower the pH of the environment, the harder for radish seeds to germinate and to survive.It would be appropriate to conclude that plant species with a narrow range of pH are in trouble. Most plants germinate and grow best in a pH range of 7 to 9. The higher and lower pH levels, especially of 3 and 11, drastically reduce growth of plants and crops. Acid rain is a caper since it reduces th e pH levels of soil to below 5. From the above experimental results, it suggests that acid rain may drastically reduce crops and plants
