Method for regenerating bitter herbs corm by in-vitro culture

Abstract

The invention belongs to the field of plant tissue culture technique. The invention employs the regenerative method of isolated culture of kuh-weed bulb to produce high grade tissue sprout of kuh-weed in large scale. The method overcomes the shortage of low survival rate in natural condition of the seed, affective to soil thickness of germination in winter and non germination of a large amount of winter sprout to grow into plant. The invention can meet demand of establishing aquatic vegetation and reduce water pollution.
