Özet: Gibberellins are diterpenoid, plant growth hormones and regulators, able to control some important processes in plant growing andbreeding; including stem elongation, flowering initiation, increasing fruit set and size, improving fruit shapes, induction of seedlessness,retardation or acceleration of senescence, breaking seed dormancy, in increasing crop metabolic contents, activation preferred gender organsin flowers, pollen development and germination. Some of the chemical substances occur endogenously in some parts of plant organisms. Thechemicals are also being produced commercially and commonly used in different aims via exogenous application. One of their uses isbreaking seed dormancy and activation of seed germination of fruit species. The fruit trees are mostly propagated via grafting on rootstockderived from seed and the known, valuable seeds sometimes can be hard to germinate themselves because of external or internal factors. Inthe review study, usages and effects of the exogenous gibberellins on germination of some fruit seeds at in vitro, ex vitro and nurserygermination conditions are presented.
