    Contrasting studies on photosynthetic characteristics of Zizyphus jujuba cv. Dongzao grafted seedlings from different producing places

    • 摘要: 为探讨冬枣的光合特性与规律,以河北黄骅和沧县栽植的不同产地冬枣嫁接苗为材料,采用Lico--6400光合测定系统对其光合作用指标进行测定。结果表明:不同产地冬枣嫁接苗净光合速率--光响应曲线变化趋势相似,其中冀东产地冬枣在不同光有效辐射强度下的净光合速率高于其他产地冬枣;不同产地冬枣净光合速率日变化呈不对称双峰曲线,年变化呈单峰曲线;山东庆云和河北黄骅产地冬枣的光补偿点较低,山东乐陵和河北沧县产地冬枣光饱和点较高,表现出不同的光适应能力;生产园和年份对冬枣净光合速率差异影响显著。

       

      Abstract: In order to study the photosynthetic characteristics of Zizyphus jujuba cv. Dongzao, grafted seedlings from different places, which were planted in Huanghua and Cangxian, Hebei Province of northern China, were used as experimental materials for the measurement of photosynthesis using Lico-6400. The results showed that the light response curves of net photosynthetic rate of Z. jujuba cv. Dongzao from different places were similar to each other, and the net photosynthetic rate of Z. jujuba cv. Dongzao from Jidong,Hebei Province was higher than that of others with the same photosynthetic active radiation. The diurnal variation of net photosynthetic rate exhibited dual-peak curves, and the annual variation showed single-peak curves. The light compensate points of Z. jujuba cv. Dongzao from Qingyun, Shandong Province and Huanghua were lower than that of others, the light saturation points of Z. jujuba cv. Dongzao from Leling, Shandong Province and Cangxian were higher than that of others, suggesting different ability of adapting radiation intensity. The difference of net photosynthetic rates of Z. jujuba cv. Dongzao among different orchards and varied years was significant.
