Abstract
The character of branching for two chrysanthemum (Chrysanthemum × morifolium) cvs. Jinghai and Jingyun was observed, and the changes of endogenous hormones in apical and lateral buds were investigated to determine the relationship between the pattern of hormone distribution, apical dominance, and lateral bud outgrowth. The growth rate of Jinghai lateral buds was higher than that of Jingyun. In vegetative growth stage, IAA level in apical buds of Jingyun was significantly higher than in Jinghai. After flower induction, IAA level in apical buds of two cultivars decreased remarkably, but the IAA level decreased in Jingyun faster than in Jinghai. These results showed that the higher was the IAA level in apical buds the stronger was inhibition of lateral bud outgrowth. An increase in IAA and iP/iPA and a decrease in ABA concentrations were closely associated with lateral bud growth alterations in chrysanthemum.
