Abstract
The purpose of this experiment is to assess and analyze pea plant response, and potential growth, to the hormones Auxin and Gibberellin. Six pea seeds were used to ascertain the results, two of which were utilized as a control group while the other four contained either Auxin or Gibberellin, in pairs, respectively. Given ample amounts of light, non-acidic soil and saturated in water twice a week, all of the seeds were observed over a one month period and data was recorded weekly. Results of the experiment show that only one of each pair of pea plants grew. After four weeks, seed #1 of the pea plant containing three drops of Auxin grew to 105 millimeters, seed #2 of the control group grew to 95 millimeters, and seed #1 of the pea plant containing three drops of Gibberellin grew to 113 millimeters. These results indicate that even with small amounts of Auxin and Gibberellin added, the pea plants containing those hormones grew taller than the pea plants in the control group with the Gibberellin containing plant leading by 8 millimeters. All in all, one may conclude that pea plants with either three drops of Auxin or Gibberellin partake in a bigger growth spurt than pea plants that do not contain either hormone. Introduction In order to fully understand how seed germination occurs, one needs to investigate all factors leading up to this sudden growth. Out of the many stimuli that direct seed development, including but not limited to the availability of water,…
