Increasing shoot branch numbers of Chrysanthemum morifolium Ramat cv. Hangbaiju (Hangbaiju) is crucial for producing high flower yields. Pot experiments were designed to evaluate the effects foliar application 6-benzylaminopurine (6-BA) combined with prohexadione-Ca (Pro-Ca) on yield and quality flowers. Foliar 6-BA Pro-Ca typically increased leaf chlorophyll content decreased soluble sugar pro...
