The Effect of Insect Repellent on the Production of Chlorophyll in Raphanus Sativus

The purpose of our experimentation was to explore the effects of insect repellent on the chlorophyll production within the leaves of the Raphanus sativus plant, more commonly referred to as the radish plant. We grew two experimental groups of the plants and one control. Each group received a different, increased amount of insect repellent over a two-week stabilizing spray period. After the plants had grown to a suitable size we tested their chlorophyll levels by use of the Hill Reaction Kit, an experimental procedure involving a methylene blue test. Using the kit we were able to test the reaction of the radish plants to the methylene solution in order to find the amount of chlorophyll present in the leaves of the different radish plants.
