Summary

Plantlets were regenerated from protoplasts of in vitro shoot cultures and leaf-derived de novo shoots of the chrysanthemum Dendranthema zawadskii x D. grandiflora. Isolated protoplasts reformed cell walls and then began to divide within 24 hours of culture in streaky plate agarose lenses surrounded by liquid V-KM medium. Twenty one days after isolation, 1 mm diameter callus clumps were transferred to shoot regeneration medium. After a further 33 days leaves became visible. Elongated shoots were rooted on half strength hormone-free MS medium.
