In-vitro culture, often used in plant propagation, is a technique where plant cells, tissues, or organs are grown in a controlled, artificial environment, typically within a laboratory. This method is notably utilized for producing disease-free plants and for rapid multiplication of new plant clones, having been established around 1980.
Key aspects of In-Vitro Culture:
- Disease-Free Plants: A primary benefit of in-vitro culture is the ability to produce plants that are free from diseases. This is crucial in agriculture, where diseases can devastate crops.
- Rapid Multiplication: This technique facilitates the rapid multiplication of new plant clones, which is valuable for quickly producing large numbers of genetically identical plants. This is especially useful for commercially valuable varieties.
- Tissue Source: The process typically starts with small pieces of plant tissue, such as the shoot apex, which is the growing tip of a shoot.
- Controlled Environment: The cultures are grown in a sterile environment, often using agar-based media supplemented with nutrients and growth regulators. This precisely controlled setting ensures optimal growth conditions.
Practical Applications
Artichoke Propagation
As an example, firms in Italy, France, and Spain are using in-vitro culture to sell artichoke plants. This showcases its practical application in the commercial plant market.
Commercial Benefits:
- Cost-Effective: By rapidly producing multiple copies of a plant, in-vitro culture is cost-effective, compared to traditional propagation methods.
- Consistency: The clones produced are genetically identical to the mother plant, guaranteeing consistent traits and plant quality.
- Year-Round Availability: The controlled environment permits the production of plants year-round, regardless of the season.
Table Summary
| Feature | Description |
