How Do Ph Values Affect Seed Germination

Hey class, for my science fair, I have decided to do a research and experimental project on how pH values affect seed germination. In order to gain knowledge about the influences of pH values on seed germination, I decided to grow red kidney beans for 10 days with all acidic, neutral, and basic water.

My hypothesis was that if multiple beans were to be grown with water containing different pH levels, then each bean plant would have different outcomes in terms of growth because depending on the pH level, the substances within the water vary and may become a harmful or a beneficial influence on the plant’s growth. I was, fortunately, correct and was able to carry out a decent test.

In the beginning of the experiment, all beans had gone through the stage, imbibition successfully. The beans itself had absorbed and filled themselves with the water available. However, the rate of imbibition was where it differed. The red kidney beans in the alkaline water absorbed the most, compared to the rest of the beans. Not long after, roots started to sprout and to be more specific, the first root to sprout had been watered with alkaline water. As a matter of fact, by the end of this experiment, the most roots sprouted were grown in alkaline water. On the other hand, in the acidic side of the scale, none of the beans had sprouted a root during …show more content…
Alkaline water had been the most beneficial to seed germination because of the different nutrients and minerals it contains. There are multiple essential nutrients that a plant must have in order to grow properly. I found out that many of these nutrients were found in alkaline water as well. Some include potassium, calcium, iron, magnesium, zinc, and copper. Therefore, alkaline water was best for seed germination in view of the fact that it increases the rate of growth and contains beneficial nutrients for the
