| 摘 要： | 大丽花花芽分化形态变化过程，可分为营养锥阶段、生殖锥阶段、总苞分化阶段、舌状花分化阶段、管状花分化阶段５个时期。其花芽分化顺序是向心的。顶生花芽和侧生花芽均由营养锥分化而成。舌状花为单性花，管状花为两性花。其花器变异十分普遍，花芽分化受光周期、扦插时间、营养水平等因素影响，因而整个花序上的舌状花与管状花数目不定。若条件适宜，大丽花全年均可形成花芽。

| Abstract: | The morphodifferentiation of dahlia flower bud is divided into five stages:vegetative cone, reproductive cone, involucre differentiation, half flourish differentiation and tubular flower differentiation. In anthotaxy differentiation of dahlia is afferent,The apical flower bud and laterval flower bud of dahlia can turen from vegetative cone and half flourish is imperfect flower and tublar floret is perfect flower. It is an usual condition for metamorphsis of dahlia flower organs. The flower bud fifferentiation is affected by photoperiod, cutting time, nutritive level, So the number of half flourish an tublar floret of one dahlia inflorescence is infinite. Under good culture condition, the flower bud of dahlia will form all around the year. |
