Study Notes
Tissue Culture Concepts
- Totipotency is the ability of a cell to give rise to a complete organism.
- The main purpose of plant tissue culture is to produce large numbers of plants that are genetically identical and free of diseases.
Types of Tissue Culture
- Micropropagation is used routinely in ornamental and horticultural crops.
- Micropropagation is the in vitro propagation of plant parts such as single cells, tissues, and organs under sterile conditions.
In Vitro Culture
- In vitro culture refers to the growth of plants or plant parts in a laboratory using artificial media, under controlled conditions.
Micropropagation Units
- When planning micropropagation units, factors such as the type of crop, size of the unit, and the market demand should be considered.
- The main purpose of a medium-scale micropropagation unit is to produce large numbers of plants for commercial purposes.
Laboratory Facilities
- The basic facilities required for a plant tissue culture laboratory include a sterile room, a growth room, and a laboratory for media preparation and plant handling.
- A large-scale micropropagation unit requires all facilities and equipment designed for optimum production flow.
- A plant tissue culture facility includes laboratories, growth rooms, and other equipment necessary for the production of large numbers of plants.
