Abstract
Dwarfism is a common mutation found in many organisms and Setaria (millets) is no different. In millets and other plants, a reduction or complete lack of production of necessary hormones such as Gibberellic acid (GA), auxin, or Brassinosteroid can cause a mutant’s vertical and sometimes outward growth to be significantly reduced when compared to a wild type of the same variety. A typical solution to this mutation is the application of a hormone solution to allow the plant’s cells and organs to have access to the hormones needed to continue growing at an average rate. We decided to test an application method by applying a solution of 15 ppm of GA in 1L of water, at three different rates to four different varieties of millet including one wild type and three different mutant types. Our experimental results come from measuring the plant’s growth (using centimeters) three times a week and recording that data to find the average growth of each group. We have been testing this experiment over the course of three weeks and will be presenting evidence to show that the application of Gibberellic acid solution improves the growth of all millets including Dwarf mutants.
