摘　　要：采用LI-6400便携式光合作用测定系统对幼龄期生长比较旺盛的3个油茶无性品系长林4号、长林166号和长林53号光合作用进行测定并进行分析。结果表明:长林4号比长林166号更适合在高温干旱和强光合有效辐射照射环境下进行光合作用,光合作用整体效率比长林166号、长林53号高。生理特征分析表明,长林4号在叶片构造和叶水分利用状况等方面的生理特征支持上述结论;长林4号在幼龄期光合特性上具有比较优良的种质优势。The LI- 6400 portable photosynthesis system was used to study the photosynthesis of three flourish Camellia oleifera clones： Changlin 4, Changlin 166 and Changlin 53 at their infant stage. The results showed that the net photosynthesis of the clone Changlin 4 was higher than that of Changlin 166 and Changlin 53. The leaf color and leaf fabric, figure and capability of water utilization of the clone Changlin 4 made it more suitable to environment of higher temperature droughty and stronger radialization. The quantity of chlorophyl and carotinoid varied remarkably in the three clones. Based on in - depth investigation,it can be concluded that the clone Changlin 4 is a superior clone of Camellia oleifera with better photosynthesis of its infant stage and more compatible to the natural environment in Jiangxi Province.
