为了筛选耐弱光油茶（Camellia oleifera）品种，于2010年10月份在广西南宁利用Li6400便携式光合作用测定系统对广西、湖南和江西选育的普通油茶6个无性系光合特性进行了测定，结果表明：不同无性系光合特性存在差异，日平均净光合速率由大到小依次排列为湘林86号〉岑软24号〉长林4号〉岑软3号〉赣190号〉岑软2号，但岑软24号在早、晚光合有效辐射较低时净光合速率分别为5．33和4．08μm1／（m2·s），均大于其它元性系，在自然生长状况下利用弱光的能力最强，其次是岑软3号。在模拟光辐射条件下，赣190号、湘林86号、岑软24号和岑软3号，光补偿点均在20μmol/（m2·s）左右，在理想状况下利用弱光能力较强，而岑软2号和长林4号光补偿点分别为50．10和44．78μmol/（m2·s），利用弱光能力较差。6个无性系中初步筛选岑软24号和岑软3号为耐弱光品种。

To select low light tolerance varieties of Camellia oleifera, photosynthetic properties of six C. oleifera clones selected from Guangxi, Hunan and Jiangxi were tested by using Li6000 portable photo- synthesis system in Nanning of Guangxi in October, 2010. The results indicated that there were differ- ences in photosynthetic properties among different C. oleifera clones. The diurnal average net photosyn- thetic rate followed the order: Xianglin 86 〉 Cenruan 24 〉 Changlin 4 〉 Cenruan 3 〉 Gan 190 〉 Cen- ruan 2. When photosynthetic active radiations were low in the morning and evening, net photosynthetic rates of Cenruan 24 were 5.33 and 4. 08 μmol/ (m2.s) respectively, greater than the other clones, which had the strongest capacity to utilize low light under the circumstance of natural growth, followed by Cenruan 3. On the condition of optical radiation simulation, the light compensation point of Gan 190, Xianglin 86, Cenruan 24 and Cenruan 3 was about 20 μ mol/ ( m2 . s), with the stronger capacity to uti- lize low light in ideal situation, while the light compensation points of Cenrnan 2 and Changlin 4 were 50. 10 and 44. 78 μmoL/ (m2 . s) respectively, with the weaker capacity to utilize low light. Cenruan 24and Cenruan 3 were selected as low light tolerance varieties among the six clones preliminarily.
