摘要
以温室内生长的红长春花[Catharanthusroseus(L.)G.Don]和白长春花[Catharan-thusroseus(L.)G.Doncv.Albus]为研究对象,通过对长春花的净光合速率日变化、叶绿素含量、光响应曲线及几项重要的光合参数等的研究,分析比较红长春花和白长春花光合生理的特性。结果表明,红长春花光合能力及利用光能的能力均强于白长春花。具体表现在:红长春花的叶绿素含量高于白长春花;红长春花的净光合速率高于白长春花;长春花在对强光的利用上表现出喜光植物的生理特性;红长春花的利用强光的能力高于白长春花;两种长春花净光合速率Pn日变化曲线趋势相同,均为单峰型。
Daily change of net light-photosynthetic rate, chlorophyll contemion, and light-photosynthetic rate curves of Catharanthus roseus and Catharanthus roseus ev. Albus in glasshouse, were studied and photosynthesis character were analyzed and compared in this study. The results showed that chlorophyll eontem of Catharanthus roseus was higher than that of Catharanthus roseus ev. Albus;photosynthetie rate of Catharanthus roseus was higher than that of Catharanthus roseus ev. Albus;Catharamhus rose us belongs to photophilous plant;the trend of daily change of photosynthetic rate were same between Catharanthus roseus and Catharanthus roseus ev. Albus were both single peak.
