- 摘 要：枣树是辽西半干旱地区主要的生态-经济型树种之一，研究其生理特征对该地区经济林产业发展具有重要意义。以辽西朝阳地区不同品种枣树为试材，采用Li-6400P光合测定系统对其气体交换指标及荧光生理指标进行了测定与分析。结果表明：各品种枣树的气孔导度(Gs)、胞间CO2浓度（Ci）、气孔限制值(Ls)及叶片光能利用率(LUE)等指差异显著，在枣树的光能利用水平方面，“大铃铛枣”、“大平顶枣”及“金丝王枣”均强于“三星枣”和“金丝蜜枣”；各品种枣树荧光特性差异显著，“大铃铛枣”和“大平顶枣”的 Fv/Fo和Fv/Fm 值均大于“三星枣”、“金丝蜜枣”及“金丝王枣”；根据不同品种枣树光化学猝灭(qP)系数及非光化学猝灭(NPQ)系数，判定各枣树品种适应环境进行初级生产的能力由小到大排序为“三星枣”<“金丝蜜枣”<“金丝王枣”<“大铃铛枣”<“大平顶枣”；各品种枣树对强光的适应能力由大到小的排序为“大平顶枣”>“金丝蜜枣”>“大铃铛枣”>“金丝王枣”>“三星枣”。 综合上述判定，“大平顶枣”、“大铃铛枣”及“金丝王枣”光化学性能要强于“金丝蜜枣”和“三星枣”。

- Abstract: Zizyphus. jujube Mill.( Z.j M.)is one of the main ecological and economical tree species in semi-arid area of the west of Liaoning Province.In this region,the study of physiological feature will be significant to economic forest industrial development.Taking different cultivars Z.j M.as materials,which gas exchange and fluorescence physiological indexes characteristics were detected and analyzed by using Li-6400 portably photosynthetic measurement system in Chaoyang areas.The results showed that,the gas exchange and fluorescence physiological characteristics of different Z.j M.cultivars were significant difference.The value of stomatal conductance(Gs)，intercellular CO2 concentration（Ci）,limiting value of stomata and efficiency for solar energy utilization of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’，and Z.j M.‘Jinsi Wangzao’ would be better than that of Z.j M.‘Jinsi Mizao’ and Z.j M.‘Sanxing Zao’；the value of Fv/Fo and Fv/Fm of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’ were greater than that of Z.j M.‘Sanxing Zao’, Z.j M.‘Jinsi Mizao’,and Z.j M.‘Jinsi Wangzao’.According to the qP and NPQ value of the different Cultivars Z.j M.,it showed that the capability of the basic-level production of them was different,the order was： Z.j M.‘Sanxing Zao’< Z.j M.‘Jinsi Mizao’< Z.j M.‘Jinsi Wangzao’< Z.j M.‘Da Lingdang Zao’< Z.j M.‘Da Pingding Zao’；furthermore,the ability of adapted to intense sunlight of them was also different,the order was： Z.j M.‘Da Pingding Zao’> Z.j M.‘Jinsi Mizao’> Z.j M.‘Da Lingdang Zao’> Z.j M.‘Sanxing Zao’> Z.j M.‘Jinsi Wangzao’.In sum,it assumed that the photochemical characteristics of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’,and Z.j M.‘Jinsi Wangzao’ would be better than that of Z.j M.‘Jinsi Mizao’ and Z.j M.‘Sanxing Zao’.
