horticultural plants like Irish potato that reproduced by tuber, sweet potato by slips and/or vine cuttings, Ginger by Rhizome, Onion and Non-tunicate, or scaly bulbs lack this protective (papery) covering and are more easily, damaged. Flood System: When the land is flat, the entire area is flooded by letting in water. In higher plants, any part of the body may, be capable of vegetative propagation. parent plants and each other, except when sudden change, mutation. e larger the corm taken for sucker production, gave the highest number of suckers compared with the smaller one, and the corm which was taken from the apical part the mother corms. 4-Dwarf rootstock colonel propagation. Bangladesh J Agr Res 33: 531-537. Many tuberous plants are propagated asexually by, division of the tubers which divided into sections each containing one or, more eyes. Plant propagation- methods and classification 3. e) For cultivating crops suitable to different climatic conditions. Uniformity of the tubers harvested from different sizes of seedling tubers was statistically similar and tubers from Desiree were statistically uniform as compared to seedling tubers. e sweet potato crop can be planted either for food and/or for, animal feed depending on the purpose and season of production. e Tunicate bulbs, have outer modied leaves, which are dry and paper thin. http//anpsa.org.au. is occurs [5]. Tubers, are divided into sections each containing one or more eyes. Bulbs are a specialized. ese plants will usually require careful cutting up, and many in some cases have only a few roots per division. hWn6>&X8,NvA6~PlQ+Kwfh9q necessitate planting in some sort of nursery bed until establishment, although in most cases they will survive if planted out straight away. The study comprised of three seed rhizome sizes viz., 20 g, 30 g and 40 g with five plant spacings viz., 25 cm 15 cm, 25 cm 25 cm, 30 cm 20 cm, 30 cm 30 cm and 40 cm 20 cm. Micro-propagation principles and concepts, commercial exploitation in horticultural crops. e other propagation method of sweet, potato is by vine cuttings.

Tubers are anatomically the same as stems having, internodes and nodes from which eyes develop containing one or more, shoot buds. immediate needs of the living things including of human beings. means.Propagation is an art of multiplication of plants. A field experiment was conducted to study the effect of seed rhizome size and plant spacing on growth, yield and quality of ginger (Zingiber officinale Rosc.) Dierent, horticultural crops can be propagated by dierent specialized organs, is propagated by vegetative propagation division of tubers. Small corms are called cormels. 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. But, In case of lower plants, propagation occurs through binary fission, budding, fragmentation, gemmae, resting buds and soredia (in lichens). Clonal; Asexual propagation; Division; Separation; Plants are the most fundamentally important things given to life. Theory. Influences of mattocking on translocation of nutrients from mother plant to daughter suckers at various physiological stages of the mother plant and under the different systems of planting have been explored by many scientists. In order to continue life on this planet, plants are the basic and. 198 0 obj <>stream varieties even if the sexual propagation method has also practiced for different plants. ey added that Sucker invigoration techniques has been, under taken at dierent areas which is important for good bunch yields. Course Description: Methods and techniques of sexual (seed) and asexual (vegetative) propagation of horticultural plants will be discussed. e size of the, sucker has positive eects on plant vigouresity and productivity of the, herbaceous and monocotyledonous crop which is propagated by its, stem with basal plate. and external factors (planting seasons, depth, spacing etc.) ey concluded that the larger size, and whole/half cut of potato tuber produces the higher tuber yields, and are less susceptible to late blight potato disease as compared to the, potato is modied root called tuberous root is perennial which grown, as annual. e line, between division and natural layering is overlap. 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. All daughter plants produced from, these organs are identical called clones of the mother plant and may, serve as food stores. Growing of tissues in controlled conditions is an advance and recent method of vegetative propagation.
