摘  要:
采用LI-6400光合测定仪对盆栽的常春油麻藤(Mucuna sempervirens)、中华常春藤(Hedera nepalensis var.sinensi)和扶芳藤(Euonymus fortunei)进行光响应曲线、温度响应曲线和相对湿度响应曲线的测定。对比分析3种藤本植物的光补偿点(LCP)、光饱和点(LSP)、最大净光合速率(Pn)、最大表观量子效率(AQYmax)等光合特性指标,并研究分析光强、温度和相对湿度对3种藤本光合特性的影响。结果表明,常春油麻藤对有效光能辐射的利用范围最大,其次是扶芳藤,再次为中华常春藤,3种藤本植物的最适温度均在26~30℃,且对高湿环境条件的适应性均比较强。

摘  要:
The light response curve,temperature response curve and relative humidity response curve of three species of liana(including Mucuna sempervirens,Hedera nepalensis var.sinensi and Euonymus fortunei) were measured with LI-6400 portable photo synthesis system,the light compensation points(LCP),light saturation compensation points(LSP),net photosynthetic rate(Pn) and the apparent quantum yield max(AQYmax) of three species of liana were analyzed,and the photosynthesis property under the influence of light,temperature and relative humidity were developed on the three species of liana.The results indicate that the ecological ranges of light adaptability of Mucuna sempervirens is the widest,Euonymus fortunei takes the second place,Hedera nepalensis var.sinensi takes the third place.The optimum temperature of three species of liana is between 26℃ and 30℃,and they are all adaptive to high humidity.
