The intention of this experiment was to find out which of the two hormones, Gibberellic Acid or Brassinosteroids, would have the greatest effect on growth among our test subjects, the organism Arabidopsis thaliana. The results of this experiment were not as we hypothesized. Gibberellic acid proved superior in cell elongation, which can be observed by way of plant height. This was a rejection to our original hypothesis, as well as a contradiction to the study: “Interactions between Brassinosteroids and Gibberellins: Synthesis or Signaling?”; the information from which we based our hypothesis (Laura JQ, et al, 2017). Not only did the plants subject to gibberellic acid show increased growth when compared to equal amounts of brassinosteroids, but also displayed superior results even when compared to amounts of brassinosteroid twice that of the presence of the acid. In addition, the cross-regulatory relationship between the two hormones was not displayed as expected.
