Addition of Gibberellin Through a Plants Lifespan (Wisconsin Fast Plant; Brassica rapa)

Alex Kirkpatrick, Melissa Vance, Kris Vance

Abstract


The effects of gibberellin have long been observed by Japanese rice farmers as a symptom of bacteria that causes abnormal height and seed production. We studied the whether the method of gibberrelin application or the time at when it was applied had any effect on the growth. 10 mL of gibberrelin was added directly to the soil for 10 plants, and 10 were sprayed in the first week. An additional 20 plants received the same treatment the following week, and 10 plants were left as the control group - without treatment. For week one and two, the number of leaves were the same for all plants, but the third week showed differences. Based on the results, it appears that the effects of gibberellin is not instantaneous, but remains in the plant for quite some time.
