What is micropropagation and its steps?
Micropropagation is the process of multiplying plant stock plant material by growing plantlets in tissue culture to produce a large number of progeny plants and then planting them out.
What is the stages of micropropagation?
These include Stage 0: Selection/maintenance of parent plant material; Stage 1: Initiation of cultures; Stage 2: Multiplication of shoots/embryos; Stage 3: Shoot elongation and rooting; Stage 4: Acclimatization (Figure 4). …
How many steps of micropropagation can be divided into?
In short, steps of micropropagation can be divided into 4 stages.
What is micropropagation method?
Micropropagation is an artificial method for rapid multiplication of plants in a short duration using the tissue or cell culture techniques in a controlled environment. The method is extensively used to produce genetically identical plants, pathogen-free plants, mass production of plants, gene conservation, etc.
What are the stages of plant tissue culture?
Steps in plant tissue culture
- STAGE 1: Initiation phase.
- STAGE 2: Multiplication stage.
- STAGE 3: Root formation.
- General procedure for plant tissue culture:
- Medium preparation:
- Plant preparation:
- Transferring the plant material to a tissue culture medium:

What is micropropagation Class 8?
Micropropagation is the artificial process of producing plants vegetatively through tissue culture or cell culture techniques. In this artificial process of propagation, plants are produced invitro by asexual means of reproduction or by vegetative propagation.
What does micropropagation include?
Introduction. Micropropagation is the clonal propagation of plants in closed vessels under aseptic conditions. It is also possible to produce plants from cells and tissues through the formation of adventitious shoots and somatic embryos (see CELL, TISSUE AND ORGAN CULTURE | In Vitro Regeneration Techniques).
What are the major operational activities in micropropagation?
Micropropagation of Picrorhiza kurroa: (A) shoot multiplication, (B) rooting of in vitro shoots, (C) hardening under greenhouse conditions, (D) micropropagated plants transferred to medicinal plant collector, and (E) rehabilitation in natural habitat.
Which explant used for gerbera micropropagation?
Numerous types of explants and protocols for micropropagation have been established and used for gerbera. Shoot tips are the commonly used explant while adventitious shoot induction from the capitulum is also a popular method.
What is the example of micropropagation?
Plants important to developing countries that have been grown in tissue culture are oil palm, plantain, pine, banana, date, eggplant, jojoba, pineapple, rubber tree, cassava, yam, sweet potato, and tomato.
Which is possible in micropropagation?
By means of induced in vitro multiplication in micro propagation, it is possible to develop plants from meristem and shoot tip cultures and from bud cultures. The apical meristem along with the young leaf primordia constitutes the shoot apex. For the development of disease-free plants, meristem tips should be cultured.
What are the steps to tissue culture?
Steps in plant tissue culture
- STAGE 1: Initiation phase.
- STAGE 2: Multiplication stage.
- STAGE 3: Root formation.
- General procedure for plant tissue culture:
- Medium preparation:
- Plant preparation:
- Transferring the plant material to a tissue culture medium:
- Technique for Plant in Vitro Culture:
Which is the fourth stage of micropropagation?
A fourth stage (IV), at which plants are transferred to the external environment, is now also commonly recognised. A general description of Stages 0-IV is therefore provided below, while the manner in which Stages I-III might be applied to different methods of micropropagation is given in Table 2.1.
What are the first steps of micro propagation?
The initial steps of micro-propagation are generally associated with several hurdles such as rate of contamination and phenolic exudation. Plant tissues are commonly associated with bacteria and fungus.
How is micropropagation used to multiply plants?
Micropropagation is the process of multiplying plant stock plant material by growing plantlets in tissue culture to produce a large number of progeny plants and then planting them out.
What are the advantages and disadvantages of micropropagation?
Often produces healthier plants, leading to quicker growth compared to those plants produced by a conventional method. The disadvantages of micropropagation are given below: The plants produced are not autotrophic. It cannot be implemented in all the crops. The plants find a problem acclimatizing to the natural environment.
