摘    要:以巢湖水域三种优势挺水植物为材料,研究了不同底质处理下植物光合生理特性的差异.结果表明,三种挺水植物地上部生物量以香蒲最大,芦苇次之,菖蒲最小.香蒲的叶绿素a(Ch1.a)、叶绿素b( Chl.b)和类胡萝卜素(Car)含量、气孔导度、胞间CO2浓度、蒸腾速率均显著大于芦苇和菖蒲,光合速率、Fv/Fm和ΦPSⅡ显著高于...

关 键 词:挺水植物  底质  气体交换  光合色素  叶绿素荧光

Abstract:To investigate the effects of sediment types on growth and photosynthetic characteristics in emergent plants,the leaf pigment contents,chlorophyll fluorescence and gas exchange of three dominant species(Phragmites communis,Typha minina and Acorus calamus) from aquatic vegetation of Lake Chaohu,which were grown in five different sediment types,were examined.The results showed that in the three emergent plant species,the shoot biomass was highest in T.minina,followed by P.communis,and the lowest in A.calamus....
Keywords:Emergent plants  sediment  gas exchange  pigment contents  chlorophyll fluorescence
