摘　　要：夏菊花品种完成低温诱导后的进一步发育要求短日照条件;发育速度(以到成蕾、开花所需的天数表示)与气温呈负相关关系(相关系数分别为-0.97和-0.96);低光照强度不能逆转已分化的花序芽,但能延缓发育的速度和使顶花序芽下部各级侧芽发育成为营养簇生枝。After cold induction, the further development of summer chrysanthemum cultivars requires short day cycles. The speed of further development is positively correlated with the atmospheric temperature, i. e, the higher the atmospheric temperature, the less the num bers of days to bud formation and flowering. Low light intensity can't result in the reverse of inflorencence buds that have formed, but delays flowering and makes the uppermost axillary branches become vegetative laterals.
