Detailed explanation-1: -Gibberellins. Gibberellins stimulate cell division and elongation, break seed dormancy, and speed germination. The seeds of some species are difficult to germinate; you can soak them in a GA solution to get them started.

Detailed explanation-2: -GA Signaling in Dormancy and Seed Germination GA stimulates the seed germination whereas, ABA is involved in the establishment and maintenance of dormancy. GA exerts its influence in two manners, first by increasing the growth potential of embryo and second by inducing hydrolytic enzymes.

Detailed explanation-3: -Gibberellin acts as the inducer, as its presence allows the enzyme induction of amylase, which can break down starch INTO a sugar to be used in the embryo. Sugar is used in the plant to synthesize proteins and break out of dormancy.

Detailed explanation-4: -The plant hormone gibberellin (GA) controls major aspects of plant growth such as germination, elongation growth, flower development, and flowering time. In recent years, a number of studies have revealed less apparent roles for GA in a surprisingly broad set of developmental as well as cell biological processes.

Detailed explanation-5: -Gibberellin promotes fruit growth and induces parthenocarpy. They break seed dormancy, bud dormancy, fruit dormancy, and promote seed germination. ABA inhibits the production of enzymes in the embryo and inhibits vivipary.
