For our science fair project, we decided to do experimentation on the effects of mycorrhizae on lettuce plants during their developing stages, as well as when drought conditions were simulated. We chose this experiment because drought is a serious issue the world is facing today which will only continue to increase in severity due to the lasting effects of global warming. If our experiment is to work, then this process could be used around the world to aid in plants survival. Our hypothesis was: If the amount of mycorrhizae in the soil is increased, then the plants will grow more efficiently and survive better during drought because the mycorrhizae will provide added nutrients and water. Mycorrhizae has a symbiotic relationship with the plants it hosts by attaching itself to the roots of the host and spreading down more into the soil. What the mycorrhizae gets out of it is carbohydrates it receives through the plants photosynthesis. What is unique about this fungus is that it can attach itself to other mycorrhizae around it and create an underground system with all the plants that are attached to the growing network of mycorrhizae, which can spread over thousands of acres. Unfortunately, our hypothesis was disproved, but the results we found were fascinating.
