摘　　要：【目的】研究核桃光合特性与其品质和产量的关系。【方法】以新疆优良核桃品种新新2和温185为材料,对照分析2个品种的光合作用及其叶绿素荧光特性,与其果实品质和产量的关系。【结果】温185和新新2光合速率与量子效率没有显著差异,这与2个品种单株产量和单产一致。2个品种在出仁率上有显著差异,即温185出仁率显著高于新新2,温185呼吸速率也显著高于新新2,出仁率可能与其代谢特性有关。总叶绿素含量之间无显著差异,而温185的叶绿素a/b值和类胡萝卜素含量均极显著高于新新2。【结论】温185和新新2的产量与其光合特性有关,而其品质与其它代谢有关。温185比新新2具有更强的光保护能力。【Objective】To reveal the relationship between photosynthetic characteristics with quality and yield of walnuts.【Method】Xinxin 2 and Wen 185 were taken as experimental materials to analyze the relationship between photosynthetic and chlorophyll fluorescence characteristics of the leaves with yield and fruit quality of the two walnut varieties.【Result】There was no significant difference in photosynthetic rate and quantum efficiency between Wen 185 and Xinxin 2,which was consistent with the yield and yield per plant of the two varieties.There was a significant difference in the rate of kernel yield between the two varieties.The rate of Wen 185 kernel was significantly higher than that of Xinxin 2,and the respiratory rate was also significantly higher than that of Xinxin 2.The rate of kernel yield may be related to its metabolic characteristics.There was no significant difference in total chlorophyll content between the two varieties,but the chlorophyll a/b and carotenoid content of Wen 185 were significantly higher than those of Xinxin 2.【Conclusion】The yields of Wen 185 and Xinxin 2 were related to their photosynthetic characteristics,and their qualities were related to other metabolism.Wen185 may have stronger light protection capability than Xinxin 2.
