For those interested in finding out a little more about tissue culture (to be discussed at the forth-coming AGM as a way of introducing new cultivars to NZ). There is a useful introductory article with pictures here on the Texas A & M University website. It starts:
Tissue culture (often called micropropagation) is a special type of asexual propagation where a very small piece of tissue (shoot apex, leaf section, or even an individual cell) is excised (cut-out) and placed in sterile (aseptic) culture in a test tube, petri dish or tissue culture container containing a special culture medium.
