Regulation of growth and flowering in chrysanthemum superbum






Journal of the American Society for Horticultural Science 107(5): 874-877

Regulation of growth and flowering in chrysanthemum superbum

Seedlings of C. .times. superbum shasta daisy varied greatly in their requirements for flowering. Some vegetatively propagated clones of selected seedlings required cold in order to flower, some required long photoperiods, some required both, and some required neither. Flowering bedding plants were produced from seed in 6-8 mo.
