Description
Dwarf and semidwarf variants of agricultural plants are used to decrease lodging without decreasing crop yield. Some dwarf genotypes lack the ability to produce the growth hormone gibberellin, and others lack complete receptor pathways. Exogenous gibberellic acid (GA) was applied to four dwarf millet genotypes over the course of six weeks to determine what pathway for dwarfism each dwarf genotype was. Statistical analysis was done to analyze the relationship between GA applications and increased plant growth. It was found that all genotypes had some response to the treatment, though some were more extreme than others. Additionally, the treatment group had longer and thinner stems and leaves, and smaller panicles. Compared to the control group, these differences could cause an increase in lodging, stem breakage, and lower crop yield. Further genetic analysis could give more information on the pathway of dwarfism for each millet genotype.
