4.1 Introduction
| Name of technique | Types of technique | |
|---|---|---|
| Culturing techniques | • Suspension culture • Callus culture • Hairy root culture • Seed culture (embryo, endosperm) | • Protoplast culture • Ovary culture • Root, shoot, and leaf culture • Flower culture (ovary, anther, pollen) |
What are the 4 stages of micropropagation?
The process of micropropagation can be divided into four stages:
- Initiation stage. A piece of plant tissue (called an explant) is (a) cut from the plant, (b) disinfested (removal of surface contaminants), and (c) placed on a medium.
- Multiplication stage.
- Rooting or preplant stage.
- Acclimatization.
What is tissue culture technique or micropropagation?
Micropropagation is the tissue culture technique used for rapid vegetative multiplication of ornamental plants and fruit trees. This method of tissue culture produces several plants. Each of these plants will be genetically identical to the original plant from where they were grown.
What are the general techniques for plant tissue culture?
The below mentioned article provides an outline on the techniques used in plant tissue culture. Some of the techniques are: (1) Preparation of Culture Medium (2) Sterilization Procedure (3) Preparation of Aseptic Plants (4) Aseptic Techniques and (5) Incubation of Culture.
What do you understand by tissue culture technique?
tissue culture, a method of biological research in which fragments of tissue from an animal or plant are transferred to an artificial environment in which they can continue to survive and function. The cultured tissue may consist of a single cell, a population of cells, or a whole or part of an organ.
What is explant in micropropagation?
Micropropagation is the aseptic culture of cells, pieces of tissue, or organs. The process of micropropagation can be divided into four stages: Initiation stage. A piece of plant tissue (called an explant) is (a) cut from the plant, (b) disinfested (removal of surface contaminants), and (c) placed on a medium.
What is multiplication in tissue culture?
Multiplication is the taking of tissue samples produced during the first stage and increasing their number. If the plant material grown is callus tissue, it can be placed in a blender and cut into smaller pieces and recultured on the same type of culture medium to grow more callus tissue.
What are advantages of Micropropogation?
Micropropagation is the practice of rapidly multiplying stock plant material to produce many progeny plants, using modern plant tissue culture methods. The main advantage of micropropagation is the production of many plants that are clones of each other. Micropropagation can be used to produce disease-free plants.
What is in vitro culture techniques?
Important steps in in vitro culture In vitro culture technique generally consists of four main steps, they are: Isolation of tissues Regeneration and callus formation Embryogenesis Organogenesis Isolation of tissues: Tissues for regeneration can be isolated with the help of sterilized blade from any plant part i.e. …
What are the types of tissue culture?
Types of Tissue Culture. The types of tissue culture can be grouped by. the structures formed in culture. Plantlets. Seedlings. Callus. Somatic Embryogenesis. Hartmann and Kester’s Plant Propagation, Principles and Practices 8th ed.
What is tissue culture method?
Tissue culture methods are also used for culturing endosperm. It is unique because it supplies nutrition to the developing embryo. It is also triploid in its chromosome constitution. Triploid plants are used for the production of seedless fruits (e.g., apple, banana etc.).
What is the importance of tissue culture?
Modern usage. Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an in vitro model of the tissue in a well defined environment which can be easily manipulated and analysed. In animal tissue culture, cells may be grown as two-dimensional monolayers (conventional culture)…
What is a tissue culture?
tissue culture. noun. : the process or technique of making body tissue grow in a culture medium outside the organism also : a culture of tissue (such as epithelium)
