The Effects of Gibberellic Acid on Seed Germination

CSEF · 2006 Plant Biology

Elizabeth Jimenez · Fremont (John C.) High School, Los Angeles

Overview

Objectives/Goals Seed germination is the process in which a shoot and a root emerge from a seed thereby ending its dormant stage. Gibberellic Acid is a naturally occuring plant hormone that triggers germination of seeds by helping them sprout. By manipulating the level of Gibberellic Acid seeds are exposed to, farmers are able to better control when their crops will sprout. As a result, farmers are able to better gauge when to harvest their crops. In my experiment I decided to study the effect of Gibberellic Acid on seed germination. I hypothesized that if Gibberellic Acid is added to seeds when they are germinating, then the seeds will germinate faster than if they were treated with only water. Results For two weeks I recorded any changes that had occured. However I was unable to collect enough data to definitevley determine wether or not farmers should routinely use Gibberellic Acid.

Summary statement

My project focused on the effect of adding Gibberellic Acid to germinating seeds.

Help received
