Propagation Methods of Selected Horticultural Crops by SpecializedOrgans: Review

Abstract

Horticultural crops are mostly reproduced by asexual methods of plant propagations to multiply their exact copy of selected clonal varieties even if the sexual propagation method has also practiced for different plants. This can be done naturally for those plants which are propagating by specialized organs or by human intervention for targeted propagation purposes. The Specialized plant organs are those plant parts which have used for storage of reserves and reproduction purposes. They reproduce by dividing and separating the organs from their mother plants and will have propagated to produce new clonal plants. Propagation by division is a form of plant propagation in which a group of plants or plant parts are cut or torn apart which each part of the divided plant contains one or more of the roots of the plant and a part of the stem of one or more stems. This method is commonly used for different economically important horticultural plants like Irish potato that reproduced by tuber, sweet potato by slips and/or vine cuttings, Ginger by Rhizome, Onion and Garlic by bulb and bulbils and Strawberry by runner. Also propagation by separation is common type in horticultural plant propagation method. It is form of asexual propagation in which easily detachable stems are severed from the mother plants and allowed to produce new plants. Different horticultural plants like Pine apple propagated by sucker crown and slip Enset by rhizome and Banana by sucker to produce their copy of new plants. In different field of horticultural crops propagation industry, identifying the appropriate plat parts that used for propagation and their methods of propagation are the basic important for plant propagators.
