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: -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-3: -Gibberellins are plant growth regulators that facilitate cell elongation, help the plants to grow taller. They also play major roles in germination, elongation of the stem, fruit ripening and flowering.
Detailed explanation-4: -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.
