MERICLONES: Numbers of Explants

Author is Robert M. [Bert] Hamilton (Compiler), posted almost 8 years ago Commercial laboratories usually produce only 5000 explants before mericloning the mother plant again, but if the mother plant is known to be stable the production can rise to 20,000. Au81-165; Hort... Read More
