Question

mention any three advantage of using vegetative propagation for growing some types of plants

Answer 1

Advantages of Vegetative Propagation are :(i) Plant which do not produce seeds, are propagated by the method e.g., sugar-cane, banana, potato, rose, orange, seedless grapes, jasmines, chrysanthemum, etc.(ii) Vegetative propagation is a cheaper, easier and more rapid method of propagationin plants than growing plants from their seeds; for example, many lilies grow very slowly and take 4 to 7 years to developed flowers, when grown their seeds, but flowers are produced only after a year or two when grown vegitatively.(iii) The trait (character) of a plant is preserved by vegetative reproduction.(iv) Thus, the plants generated from vegetative means requires less time to grow and to have the advantages of being more uniform and genetically similar to the parent stock. Another advantage is that in propagation by this methods, the plants skip the risky seedling stage in which a number ofplants die under adverse conditions. Many seedless verities of grapes, banana and oranges are produced by this method.However, there are some disadvantages associated with this mode of reproduction. Plants grown by this method lose vigour and become prone to diseases.

Answer 2

(i) The plants grown by vegetative propagation usually needs less attention in their early years than the plants grown from seeds.    
(ii)The plants are genetically similar.
 
(iii)It helps in producing those plants which either produce very few seeds orproduce such seeds which are not viable.
 
(iv) It can be used to produce plants that reach maturity and produce fruits and seeds faster
