BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Gibberellins (GAs) affect flowering in a species-dependent manner: in long-day and biennial plants they promote flowering, whereas in other plants, including fruit trees, they inhibit it.

Detailed explanation-2: -Gibberellins, which are a group of plant hormones responsible for growth and development, are important for initiating seed germination . Low concentrations can be used to increase the speed of germination, and they stimulate cell elongation and cause plants to grow taller. They are naturally produced by seeds.

Detailed explanation-3: -Gibberellic Acid Signaling Is Required to Induce Flowering of Chrysanthemums Grown under Both Short and Long Days.

Detailed explanation-4: -Gibberellins have striking growth-promoting effects. They speed the elongation of dwarf varieties to normal sizes and promote flowering, stem and root elongation, and growth of fruit. Such elongation resembles in some respects that caused by IAA, and gibberellin also induces IAA formation.
