Gibberellic acid (Ga3)
is a hormone found in plants and fungi. It helps to germinate seeds by activating the genome of dormant cells that are in a repressed state and is suggested the possibility that GA3 breaks seed dormancy by a mechanism of gene derepression. Gibberellic Acid is commonly used with carnivorous plant seeds that are very hard to germinate because they are imposed by the seed coats, which form a significant barrier to water uptake. The dormant embryo can be activated either by removal of the seed coat, which increases 02 supply and leaching of endogenous inhibitors or by treatment with a high concentration of GA3. The effect of GA3 is correlated with a very small increase in the respiration rate, therefore, growth is not limited by the low internal 02 concentration.
In short, seeds have a protective outer layer that keeps seeds from germinating too soon. Typically, seeds are formed in the fall and need to survive the winter months without germinating, otherwise, the cold and dry season will prevent the seedling from surviving. When spring arrives, warmer temperatures and heavy rainfall tend to arrive as well. This gradual change begins to break down that protective layer which then allows water to penetrate into the seeds. The moisture and oxygen water gives activates the seed and germination begins.
There are many reasons why some seeds have a very hard preservative outer layer. The reasons depend on the region from which the seeds populated. Some seeds need extreme weather fluctuations, most of the time they even need a couple of season changes before the outer layer is broken down. There are even seeds that need natural fires for the seeds to have that layer broken down, and the most common are seeds that need to be digested by an animal for their stomach acid to break down this layer. They later excrete the seeds elsewhere. So, Ga3 prevents the need for those conditions which aid in faster germination for seeds that are very hard to sprout. It is even proven that it helps in bettering a seedling's root system.
