Learn to Grow Plants using Tissue Culture -Studying at Home

 
Tissue culture involves growing plants from very small sections (sometimes microscopic) in a laboratory. It is a propagation method which is being increasingly used. Tissue culture is not appropriate for many plants, but for others such as orchids, some indoor plants and in particular, many new plant varieties, it is a very popular propagation method.

Quote from Principal, Horticulturist and garden author John Mason: 

"Since developing this course in the late 1980's, I've encountered graduates on many occasions who have gone on to start their own tissue culture facility, and others who have successfully found employment working in a larger tissue culture enterprise. The course continues regular reviews and updates, and today reflects the input of more than a dozen tissue culture experts, biotechnologists and horticulture professionals."
