Answers
in vegetative propagation new plants are produced from the organs of old plants .
METHODS :-
- CUTTING - in this method of propagation and part of the plant is cutted and buried or interred partly in the soil . e.g. rose , grapes
- LAYERING - the branch of plant in buried or interred in soil or in organic matter without detaching it from their parent . e.g. lemon , guava , hibiscus , etc.
- GRAFTING - selected breed plant stems are grafted over the stumps of their related breeds to produce desired fruits . e.g. mango , peach , etc.
this are the most important artificial methods because sometimes it is arduous to get new plants from seeds and their maybe many factors responsible for this likes seeds are not germinating in its native land and also the climate motivates it and the most important reason that is it takes many years to obtain their products .
- IN VITRO MICRO PROPAGATION - in this production of new plants from isolated plant tissues ( group of totipotent cells) in a synthetic medium of culture solution , this method is use for the production of ornamental plants like orchids .
the above procedure use to maintain the vegetative species and more rapid method propagation to get traits of the parents and preserved . the plants receives a domination over their surrounding by producing large number of plants .
Answer:
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or a specialized reproductive structure
Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
There are several advantages of vegetative reproduction, mainly that the produced offspring are clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. It can be economically beneficial for commercial growers to clone a certain plant to ensure consistency throughout their crops.Vegetative propagation also allows plants to avoid the costly and complex process of producing sexual reproduction organs such as flowers and the subsequent seeds and fruits.For example, developing an ace cultivar is extremely difficult, so, once farmers develop the desired traits in lily, they use grafting and budding to ensure the consistency of the new cultivar and its successful production on a commercial level. However, as can be seen in many variegated plants, this does not always apply, because many plants actually are chimeras and cuttings might reflect the attributes of only one or some of the parent cell lines. Vegetative propagation also allows plants to circumvent the immature seedling phase and reach the mature phase faster. In nature, that increases the chances for a plant to successfully reach maturity, and, commercially, it saves farmers a lot of time and money as it allows for faster crop overturn.
Vegetative reproduction offers research advantages in several areas of biology and has practical usage when it comes to afforestation. The most common use made of vegetative propagation by forest geneticists and tree breeders has been to move genes from selected trees to some convenient location, usually designated a gene bank, clone bank, clone-holding orchard, or seed orchard where their genes can be recombined in pedigreed offspring.
A major disadvantage of vegetative propagation is that it prevents species genetic diversity which can lead to reductions in crop yields.The plants are genetically identical and are all, therefore, susceptible to pathogenic plant viruses, bacteria and fungi that can wipe out entire crops.
