摘要
比较了3种不同软枣猕猴桃净光合速率对光强和CO2浓度的响应特性。结果表明:3种软枣猕猴桃Pn值随光强和CO2浓度升高而逐渐增大。魁绿、8401和9701的光饱和点(LSP)分别为1 590、1 321、1 670μmol.m-2.s-1,光补偿点(LCP)为51、9、33μmol.m-2.s-1,CO2饱和点(CSP)分别为1 290、1 316、1 280μmol.mol-1,CO2补偿点(CCP)为119、123、63μmol.mol-1。综合分析后认为软枣猕猴桃具有阳生植物的特性;8401耐阴性较强,能够在林间种植;9701是一个适应性强、高产低耗的优良品系。
This experiment was to study the responses of net photosynthetic rate to light intensity and CO2 concentration in different series Actinidia arguta（Seib.et Zucc.） Plangch.ex Miq.by the CIRAS-2 portable photosynthetic system.The results showed that the net photosynthetic rate of three different Actinidia arguta（Seib.et Zucc.） Plangch.ex Miq.increased with the raising of light intensity and the concentration of CO2.The light saturation point for the cultivar kuilv and two strains 8401,9701 were 1 590 μmol·m^-2·s^-1,1 321 μmol·m^-2·s^-1 and 1 670 μmol·m^-2·s^-1 respectively,and the light compensation point were 51 μmol·m^-2·s-1,9 μmol·m^-2·s^-1,33 μmol·m^-2·s^-1.The CO2 saturation and compensation point were 1 290 μmol·mol^-1,1 316 μmol·mol^-1,1 280 μmol·mol^-1,119 μmol·mol^-1,123 μmol·mol^-1 and 63 μmol·mol^-1.In conclusion,the Actinidia arguta（Seib.et Zucc.） Plangch.ex Miq.had the same characters with heliophyte,while 8401 was resistive to low light and could be plant in the woods,the character showed that 9701 was a excellent strains with well-adapted and higher production.
