Effect of Weekly and Triweekly Application of Growth Hormone Gibberellin on Dwarf Millet Plants

Plant biology students teamed up with statistics students to examine the effects of the plant growth hormone gibberellin on mutant millet plants. Dwarf mutant millets exhibit stunted growth either because they do not produce gibberellin on their own, or because they lack the mechanisms to effectively use gibberellin. By growing some of these mutants in the greenhouse, applying a gibberellin solution to them, and observing their growth response, we can identify which kind of mutant the plant is. We are also examining the importance of frequency of gibberellin application, with some plants receiving one application of gibberellin per week, and some receiving three
