Experimental work in agrigenetics showing young seedlings, developed from tissue cultures, & now growing in culture medium in a petri dish. Tissue culture involves the growing of isolated plant cells, or a single cell, taken from almost any part of the parent plant. These cells are reared under controlled conditions in a sterile growth medium. Whole plants can often be regenerated from tissue cultures. This technique enables prolific & rapid propagation of some plants, proving useful to commercial growers. It has been used to free crops of virus infection, since the virus does not penetrate certain tissue.
