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.］
