摘  要:为从叶绿素荧光的角度阐明紫花丹参产量高于白花丹参的原因,探讨紫花丹参和白花丹参产量和叶绿素荧光差异内在关系,在山东农业大学农学实验站,利用便携脉冲调制式荧光仪在丹参快速生长期测定叶片的叶绿素荧光参数,并对其荧光特性进行综合评价。结果表明,紫花丹参的最大荧光、PSII最大光化学效率、潜在光化学效率、实际光化学效率、PSII光化学猝灭显著高于白花丹参,表明紫花丹参光合电子传递效率、光合能力高于白花丹参。由此推测,紫花丹参产量高于白花丹参的重要原因是紫花丹参对光能的利用率高于白花丹参。To clarify Salvia miltiorrhiza Bunge fromthe perspective of chlorophyll fluorescence yield higher than S.miltiorrhiza Bunge var alba C.Y,explore S.miltiorrhiza Bunge,S.miltiorrhiza Bunge var alba C.Y.and chlorophyll fluorescence differences inherent relationship,in the shandong agricultural university agronomy experiment stations use portable pulse modulation fluorometer in S.miltiorrhiza growing up fast determination of chlorophyll fluorescence parameters of leaves,and the comprehensive evaluation of fluorescence properties.Results show that S.miltiorrhiza Bunge fluorescence,the largest PSII photochemical efficiency,the largest potential photochemical efficiency,the actual photochemical efficiency,PSII photochemical quenching is significantly higher than S.miltiorrhiza Bunge var alba C.Y.,showed that S.miltiorrhiza Bunge photosynthetic electron transport efficiency,photosynthetic capacity is higher than S.miltiorrhiza Bunge var alba C.Y..Therefore,it was speculated that the important reason for the higher yield of radix S.miltiorrhiza was that the utilization rate of light energy of S.miltiorrhiza Bunge was higher than that of S.miltiorrhiza Bunge var alba C.Y..
