Description
Plant growth hormones are widely used in the agricultural industry to manipulate the growth of crops. Dwarf mutant variants of plants have been found to have a variety of mutations that inhibit the synthesis and metabolism of gibberellin, a major plant growth hormone (Phinney 1956). Observing the effect that the application of gibberellin has on the growth in 2 types of dwarf mutant millet variants will allow us to determine the type of mutation present. Applying a gibberellin solution is expected to increase the rate of stem elongation in variants with the mutation that inhibits the production of gibberellins. If there is no significant difference in the rate of stem elongation between treatment levels, then the mutation is deactivating gibberellins produced by immediately binding to a hydroxyl group (Bilova et al. 2016). Determining the mutation that is resulting in dwarf mutant types will assist in proper usage of plant growth hormones in the field of agriculture.
