为了研究海南油茶光合效率的高低及不同无性系之间光合特性的差异,筛选高光效的海南油茶无性系,以初步筛选的5个油茶优良无性系‘海南2号’、‘海南6号’、‘海南9号’、‘海南18号’和‘海南19号’为试材,利用Li-6400xt便携式光合作用测定系统,测定了其光合作用日变化及光合-光响应曲线和光合-CO_2响应曲线,结果表明:‘海南2号’的净光合速率日变化呈单峰曲线,其它4个油茶无性系的净光合速率日变化呈双峰曲线;‘海南18号’的蒸腾速率呈单峰曲线,其它4个油茶无性系的蒸腾速率呈双峰曲线,峰值分别出现在9:00和15:00; ‘海南18号’和‘海南2号’气孔导度的日变化呈单峰曲线,‘海南9号’、‘海南19...

In order to study high and low of photosynthetic efficiency and differences of photosynthetic characteristics between different clones of Camellia oleifera in Hainan, screening of high photosynthetic efficiency of clones of Camellia oleifera in Hainan province. The photosynthesis diurnal changes, photosynthetic-light response curve and photosynthetic-CO_2 response curve for net photosynthetic rate of 5 Camellia clones in hainan: 'Hainan 2’, ‘Hainan 6’, ‘Hainan 9’, ‘Hainan 18’ and ‘hainan 19’ were measured with Li-6400 photosynthetic in...
