Cultivating method of ball-shaped gerbera coenospecies

Abstract

The invention provides a cultivating method of a ball-shaped gerbera coenospecies, comprising the following steps of: selecting parents; pollinating crossly; managing the growth of a pollinated maternal plant till a first generation seed is gained; sowing the first generation seed till a plantlet grows; transplanting the plantlet till an anthesis; respectively selecting single plants with high polyphyll degree as a female parent and a male parent; collecting the pollen of multiple male parent single plants, uniformly mixing, and then pollinating crossly to obtain a second generation seed; sowing the second generation seed till the plantlet grows; selecting a single plant of ball-shaped gerbera when the plantlet is transplanted till the anthesis, and using a flower bud with an unexposed core as an explant so as to obtain a tissue culture plantlet of the stable ball-shaped gerbera coenospecies with great high ornamental value through induction cultivation, rooting cultivation and transition cultivation. The cultivating method is an effectively method for cultivating the ball-shaped gerbera coenospecies.
