采用不同LED光源照射植株，研究不同光质、不同补光时间对设施越冬辣椒光合参数及叶绿素荧光参数的影响。结果表明：不同LED光源、不同补光时间对辣椒叶片的光合速率、气孔导度、蒸腾速率、胞间CO2浓度以及叶绿素荧光参数Fv′/Fm′，qN，ΦPSⅡ，ETR，qP均有显著的影响。采用较短补光时间（6 h和8 h），RB光和B光均能显著提高辣椒叶片的光合速率、胞间CO2浓度和ΦPSⅡ，ETR，而且补光6 h的效果好于8 h；采用较长补光时间（10 h）时，RB光能显著提高Fv′/Fm′，而W光及RB73光却耗掉更多的热能。 RB83处理6h和8h能显著提高辣椒的光合作用，可作为设施辣椒越冬生产的补光光源。

The effect of differernt LED light quality treatment on photosynthesis and chlorophyll fluorescence parame -ters of overwintering pepper in greenhouse was studied .The results showed that the photosynthesis rate , stomatal con-ductance, transpiration rate, intercellular CO2 concentration and Fv′/Fm′, qN,ΦPSI , ETR, qP had significant im-pact under differernt LED light quality and differernt supplemental time on pepper leaves .Treated with short time (6 hours and 8 hours), the photosynthetic rate, intercellular CO2 concentration,ΦPSI and ETR of pepper were signifi-cantly improved under RB light and B light , and supplementary lighting for 6 hours was better than 8 hours.Treated with long time (10 hours), Fv′/Fm'was significantly improved under RB light , but more heat was disspated under W light and RB73 light.Treatment under RB83 light for 6 h and 8 h can significantly improve the photosynthesis of pep-per, therefore the two treatments can be used as supplemental light in greenhouse production of overwintering pepper .
