摘　　要：[目的]探索遮阴对朱顶红叶绿素含量及荧光参数的影响。[方法]以朱顶红“红狮”(Hippeastrum striatum‘Red Lion’)、“红宝石之星”(Hippeastrum striatum‘Ruby star’)、“月色”(Hippeastrum striatum‘Moonlight’)3个品种为研究对象,研究不同遮阴处理(全光、遮阴度分别为30%、60%、90%)对其叶绿素a+b含量和叶绿素荧光动力学参数的影响。[结果]3个朱顶红品种叶绿素a+b含量均随着遮阴程度的增强而增大,叶绿素a/b值则随着遮阴程度的增强而减小。品种“红狮”和“月色”的荧光参数(F_(v)/F_(o)、F_(v)/F_(m))均随着遮阴程度的增加呈先增大后降低的趋势;而品种“红宝石之星”的F_(v)/F_(o)则呈持续增加的趋势。[结论]该研究可为朱顶红不同品种的园林应用提供科学依据。[Objective]Effects of shading on the chlorophyll content and fluorescence parameters of three Hippeatrum striatum cultivars.[Method]The effects of different shading intensity(full light,shading treatments of 30%,60%and 90%)on the chlorophyll content and fluorescence parameters of three Hippeastrum striatum cultivars of‘Red lion’,‘Ruby star’,‘Moonlight’were studied.[Result]The results showed that the content of total chlorophyll a+b of three Hippeastrum striatum varieties was increased,as the deep of shade treatment.But the chlorophyll a/b was decreased.The fluorescence parameters(F_(v)/F_(o),F_(v)/F_(m))of the‘Red lion’and‘Moonlight’were increased first and then decreased,as the deep of shade treatment,while the F_(v)/F_(o) of‘Ruby star’had continued to increase.[Conclusion]This study can provide a scientific basis for the garden application of different Hippeastrum striatum varieties.
