A callus is a mass of undifferentiated plant cells that forms at a wound site or in tissue culture.
Also called / Category:
Callus tissue / Plant, Botany & Anatomy
Key takeaways:
- Calluses form in response to plant injury or tissue culture conditions.
- They are critical in plant propagation and tissue culture techniques.
- Callus formation is a natural healing process for plants.
What it is / How it shows up:
Callus typically appears in discussions about plant tissue culture, a method used for cloning plants or propagating them in a controlled environment. In cannabis cultivation, callus tissue can be used to regenerate whole plants, especially when genetic replication is desired. This mass of cells is often formed at the site of a cut or injury when plants are being propagated or during tissue culture processes. It is an essential part of plant biotechnology, allowing for the regeneration of plants from small tissue samples.
How it’s measured or identified:
- Visual inspection for mass formation at wound sites.
- Observation of colour and texture changes in tissue culture.
Use in context:
- Plant growers use callus formation to propagate new cannabis plants.
- Tissue culture labs examine callus growth to ensure healthy plant development.
- Callus tissue helps in breeding and genetic studies of cannabis.
Safety & compliance in Canada:
- Ensure callus formation techniques comply with Canadian agricultural regulations.
- Testing and documentation are required for commercial use of tissue-cultured cannabis.

FAQs:
What conditions are needed for callus formation? Callus formation requires a sterile environment, appropriate growth media, and controlled temperature and humidity.
Can all cannabis plants form callus tissue? Most cannabis plants can form callus tissue under the right conditions, although some strains may respond better than others.
