| Morel with Martin (Morel and Martin, 1952), recovered
virus-free Dahlia plants from infected individuals by excising and culturing
their shoot tips in vitro. The basis of this approach is that even in a
virus-infected plant the cells of the shoot tip are either free of virus
or carry negligible amounts of virus. This important technique, has become
a viable horticultural practice.
While applying the technique of shoot-tip culture for raising virus-free individuals of an orchid, Morel (1960) also realized the potential of this method for the rapid propagation of these plants. The technique allowed the production of an estimated 4 million genetically identical plants from a single bud in a period of 1 year. |
