摘要: 采用LI-6400便携式光合测定系统，对3个油茶Camellia oleifera新品种华硕华金华鑫的光合生理指标及叶绿素质量分数进行测定。结果表明：①3个油茶品种叶片的净光合速率（Pn）日变化均呈宽大的单峰型，不存在光合午休现象，9：00时达到最大值。②华硕华金华鑫的光补偿点分别是43.81，58.49和54.24 molm－2s－1，光饱和点分别是693.2，638.8和684.85 molm－2s－1，对光强的适应范围大小为华硕＞华鑫＞华金。③华硕华金华鑫的总叶绿素质量分数分别为1.35，0.97和0.90 mgg－1。净光合速率与叶绿素a呈极显著负相关关系（P＜0.01），相关系数为－0.947；与叶绿素b，总叶绿素质量分数和叶绿素a/叶绿素b之间相关性不显著。综合净光合速率（Pn），表观量子效率（AQY）和叶绿素质量分数等可知华硕和华鑫的光合性能较强。图2表4参13

Abstract: The aim was to study photosynthetic characteristics of three new Camellia oleifera （oil tea） cultivars （Huashuo，Huajin，and Huaxin） and provide reference for the cultivation of Camellia oleifera （oil tea）. The index of eco-photosynthetic characteristics and the chlorophyll content for three new Camellia oleifera （oil tea） cultivars were investigated and their correlation was analyzed. Randomized design was applied in this study，three replications were designed and each treatment was sixty plants. Results for all three cultivars showed that net photosynthetic （Pn） diurnal change curves were single peaked，the midday depression phenomenon for photosynthesis did not occur，and the peak was at 9：00. The light compensation and saturation points （LCP and LSP） for Huashuo were 43.81 and 693.2 molm－2s－1，for Huaxin，respectively，were 58.49 and 638.8 molm－2s－1，and for Huajin were 54.24 and 684.85 molm－2s－1. The order for adaptation range of light intensity was：Huashuo＞ Huaxin ＞ Huajin. Chlorophyll content for Huashuo was 1.35 mgg－1，for Huaxin was 0.97 mgg－1，and for Huajin was 0.90 mgg－1. Also，photosynthetic rates were negatively correlated with chlorophyll a （r = －0.947，P＜0.01），but were not correlated to chlorophyll b or chlorophyll a/chlorophyll b. Thus，Pn，LCP，LSP and chlorophyll content，showed that Huashuo andHua-xin had a better in photosynthetic capability.［Ch，2 fig. 4 tab. 13 ref.］
