The 1960's saw a dramatic conquest of the major problems confronting orchid propagation. The orchids were slow to propagate vegetatively and were almost universally infected with viruses that caused a dramatic shortening of the shelf life of the flowers. Morel (6) described the methods for producing virus-free Cymbidium orchids and how to use tissue culture for clonal propagation of orchids. Scully (10) described clonal propagation of Phalaenopsis. Sagawa and Shoji (9) described clonal propagation of Dendrobiums. Scully (10) wrote about meristem culture of Cattleya orchids.

So here, after decades of steady but slow improvement in vegetative orchid propagation, tissue culture burst on the scene successfully. Where did this put our expectations? Why, we were
