Effect of pH on Mycorrhizal Plant Growth in Two P Concentrations

Mahak Jain and Joanna Kong. JFK Memorial High School, Iselin, NJ

Mycorrhizae can aid plants best in conditions of low pH concentrations. The effect of a lower pH level on the growth rate of plants in low P concentration versus high P concentration soils on mycorrhizal grass was tested. There were three hypotheses: (H1) In a neutral pH, there will be a significantly higher growth rate in soil of low P concentration versus soil of high P concentration. (H2) In an acidic pH, there will be a significantly higher growth rate in soil of low P concentration versus soil of high P concentration. (H3) The growth rate in soil of low P concentration and low pH will be significantly higher than the growth rate in soil of low P concentration and neutral pH. H1 was accepted at a 95% significance level; H2 and H3 were rejected. Overall, the research was found to be insignificant, though the results may have been skewed by the growth of one pot.
