摘要
夏菊品种夏黄完成春化过程所需的温度范围较宽，１６℃以上的温度即能满足其春化需求。气温高于３０℃时夏黄开花延迟，表明其花芽发育存在某个适宜的高温界限。冬季日照强度较弱时，摘心以后全天用高压钠灯（光强２０００ｌｘ）补光３５ｄ显著促进了夏黄侧枝的早期营养生长和开花。
The requirement for vernalization of a summer-flowering chrysanthemum cultivar‘Summer Yellow’could be met in a very wide range of temperatures even over 16℃.When the day temperature was over 30℃,flowering of this cultivar was delayed,so an optimal limit of high temperature existed for flower development of summer-flowering chrysanthemum.Under natural low-light conditions in winter,all day supplemental lighting with high pressure sodium lamp providing an irradiance of 2000lx for 35 days after pinching significantly promoted early vegetative growth and flowering of the axillary shoots.
