摘要
为了探讨切花月季在滇中地区的高产优质栽培措施，对黑魔术、沃蒂、帕里欧3个月季品种在设施条件下的光合特性及叶绿素含量进行了研究。结果表明，无论在什么季节和生育期，3个品种的叶片光合作用日变化皆表现出明显的光合“午休”现象，最大光合速率出现在上午10：00～11：00。植株中部叶片的净光合速率最高，其次是上位叶，下位叶最低，而不同位置叶片的叶绿素含量变化趋势是中位叶〉下位叶〉上位叶。在滇中地区，月季中午光合速率的降低主要与温室中高温有关，而不同叶位光合速率的变化与光环境、叶绿素含量及叶龄有关。根据研究结果，讨论了滇中地区设施条件下切花月季的一些栽培措施。
Rosa hybrida is not only a fan,us traditional flower in China, but also one of the most key cut-flowers, playing an important role in the flower production and trade in the world. To develop the cultivation strategy of high yield and quality for cut-flower rose in the middle of Yunnan province, the photosynthetic characteristics and chlorophyll content of three cultivars （Black Magic, Virdi and Pareo） was studied under greenhouse condition. In any season and any developmental stage, the photosynthetic rates of three cultivars showed significant depression at midday. The maximal photosynthetic rates were observed between 10： 00-11：00 in the morning. The middle leaves of rose canopy have the highest photosynthetic capacity, followed by the upper leaves and lower leaves; while the changes in chlorophyll content with leaf position exhibited the order middle leaves 〉 lower leaves 〉 upper leaves. The midday depression in photosynthetic rates of cut-flower rose in the middle of Yunnan province was correlated to the high temperature in the greenhouse, and while the change in photo- synthetic rates with leaf position is correlated with light environment, chlorophyll content, and leaf age. The cultivation strategy for cut-flower rose in the middle of Yunnan province is discussed.
