摘    要:【目的】 研究宁夏灵武长枣不同冠层光质组成对光合特性及果实品质的影响,筛选出影响光合特性及果实品质的主要波长可见光。可为灵武长枣适宜的光环境选择和从树冠结构与光质调控提高果实品质提供理论和技术支撑。【方法】 测定灵武长枣不同冠层光质组成、光合特性及果实品质,采用方差分析及多元统计分析方法。【结果】 灵武长枣不同冠层光质中,总绝对辐射能表现为上层>外部>中部>中层>下层>内部;红光绝对辐射能从上层到下层及内部到外部分别占不同冠层总绝对辐射的29.85%、20.19%、35.26%、29.90%、17.35和44.05%。叶片光合参数均与蓝光绝对辐射能呈正相关,与绿光绝对辐射能呈负相关;类胡萝卜素、叶绿素、花色素苷及类黄酮与紫光绝对辐射能均呈正相关,而可滴定酸、可溶性糖和花色素苷与蓝光绝对辐射能呈正相关,叶绿素与绿光绝对辐射能呈正相关,叶绿素、类胡萝卜素和类黄酮与红光绝对辐射能呈正相关。【结论】 增加波长较长的红光可以提高光质质量,红光是灵武长枣光合特性及果实品质的主要影响因子,在生产中补充370~470 nm和600~770 nm波长的光质,提高叶片光合作用及果实品质。

Abstract:【Objective】 In order to explore the effects of different canopy light quality components on photosynthetic characteristics and fruit quality of jujuba, the main wavelengths of visible light that affect photosynthetic characteristics and fruit quality were selected. 【Method】 The composition of light quality,photosyntheticcharacteristicsand fruit quality of different canopy of jujuba were determined by variance analysis and multivariate statistical analysis. 【Result】 The total absolute radiant energy of different canopy of jujube was as follows: upper layer > outer layer > middle layer > middle layer > lower layer > inner layer; the red absolute radiant energy accounted for the total of different canopy respectively from upper layer to lower layer and from inner to outer layer 29.85%, 20.19%, 35.26%, 29.90%, 17.35 and 44.05% of absolute radiation. The photosynthetic parameters of leaves were positively correlated with the absolute of blue light, negatively correlated with the absolute radiation energy of green light; the carotenoids, chlorophyll, anthocyanins and flavonoids were positively correlated with the absolute radiation energy of violet light, while the titratable acids, soluble sugars and anthocyanins were positively correlated with the absolute radiation energy of blue light, the chlorophyll was positively correlated with the absolute radiation energy of green light, and the chlorophyll and carotenoids were positively correlated with the absolute radiation energy of blue light There was a positive correlation between auxin and flavonoids and the absolute radiant energy of red light. 【Conclusion】 Increasing longer wavelength of red light can improve the quality of light. Red light is the main factor affecting the photosynthetic characteristics and fruit quality of jujube. It is suggested to supplement 370-470 nm and 600-770 nm wavelength of light quality in production to improve leaf photosynthesis and fruit quality.
Keywords:Lingwu long  Jujube light quality composition  photosynthetic characteristics  fruit quality
