摘要： 为探讨不同LED橙蓝光质配比对滇重楼光生物学特性的影响，同时为LED光源在滇重楼生产上的应用提供理论依据，以3年生滇重楼种苗为试验材料，采用波长为620 nm的橙光和波长为460 nm的蓝光组成的组合光源，设置了4个光质处理，分别为O:B=2:1、O:B=4:1、O:B=6:1、O:B=8:1，对滇重楼叶片生物学鲜重、光合特性和叶绿素荧光参数进行了研究。结果表明，O:B=4:1处理最利于滇重楼叶片光合色素的合成，其传递光能的效率最高，O:B=8:1处理最低。O:B=4:1处理的滇重楼叶片净光合速率、气孔导度、胞间CO2浓度、蒸腾速率均为最高，O:B=2:1处理各项荧光指标都最低。O:B =4:1处理Fv/Fm、Fv''/Fm''、ΦPSⅡ、qP最高。综合分析滇重楼叶片光合特性和荧光特性，以O:B=4:1对促进滇重楼叶片的光合作用最有利。

Abstract: In order to study the effect of different ratios of orange and blue LED light on photobiological characteristics of Paris polyphylla var. yunannensis, and provide a theoretical basis for the LED light used in the production of P. polyphylla var. yunannensis, 3-year-old seedlings of P. polyphylla var. yunannensis were selected as materials. Four light quality treatments were set by orange 620 nm and blue 460 nm LED light as O:B=2:1, O:B=4:1, O:B=6:1, and O:B=8:1, the influences on biological fresh weight, photosynthetic characteristics and chlorophyll fluorescence parameters were studied. The results showed that the combination of O:B=4:1 was most beneficial to the synthesis of photosynthetic pigments, with the highest efficiency of passing luminous energy, while the set of O:B=8:1 had the lowest one. The net photosynthetic rate, stomatal conductance, intercellular CO2 concentration and transpiration rate were the highest under the combination of O:B=4:1, while O:B=2:1 ranked the lowest. Besides, O:B=4:1 combination also owned the highest parameters in Fv/Fm, Fv''/Fm'', ΦPSⅡ, qP. As a conclusion, all photosynthesis and fluorescence parameters showed that O:B=4:1 combination was most advantageous to photosynthesis of Paris polyphylla var. yunannensis leaves.
