METHOD FOR INDUCTION OF COMPACT SHOOTS AS PROPAGULE OF POTATO

摘要

The present invention relates to a method for inducing a compact shoot, which comprises cultivating a potato plant concomitantly with treating said potato plant with a plant growth inhibitor to stimulate lateral buds or axillary buds of said potato, whereby said compact shoot as a propagule is generated and serves as a vegetative tissue or organ. Unlike conventional propagation methods using tuber-shaped seed potatoes through in vitro culture, soil culture and hydroponic culture, the present invention can provide compact shoots being subject to suitable inhibition of internodal growth for application purpose. The compact shoots of this invention can be served as a propagule for potato propagation, replacing conventional seed potatoes or being employed as a propagule for production of conventional seed potatoes. According to the present invention, the improved substitutes of virus-free potatoes can be rapidly produced in a massive manner.
