Does Rain falling on leaves and Saturation of the Soil Affect Spinach Chemistry Differently (Summer 2012 – Fall 2012). Plants were divided into four groups. The first received no extra water. The second was placed in trays to keep the soil saturated. The third was raised off the ground and had plastic cones over them to prevent the precipitation from reaching the soil. The fourth received both water treatments. TPC and antioxidant content were measured. The set-up and analysis were similar to my previous experiments, but I also developed a 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay to measure levels of antioxidants. I am currently writing a manuscript for this project to submit to AOB Plants.
The Effect of Increased Intensity and Duration of Precipitation on Spinach Chemistry (Fall 2011 – Spring 2012). A rainmaker was used to create different length precipitation treatments with different intensities that were based on precipitation data or future predictions based on climate change models for areas where spinach is typically grown. This was the first experiment I completely designed and ran on my own. I used the FC assay to analyze the samples and analyzed my own data. I also planned an event where I presented my results to members of the biology department and Tufts community.
