盐胁迫对芦苇与碱蓬叶绿素荧光特性的影响
Effects of salt stress on chlorophyll fluorescence characteristics of Phragmites australis and Suaeda glauca
[目的]阐明盐胁迫下芦苇(Phragmites australis)与碱蓬(Suaeda glauca)的荧光特性与光保护机制。[方法]采用盆栽实验,设置盐浓度分别为 0%(对照)、0.5%(C1)、1%(C2)、1.5%(C3)、2%(C4)、2.5%(C5)和 3.5%(C6),测定芦苇与碱蓬幼苗的光合色素含量与叶片叶绿素荧光参数,分析其变化规律。[结果]在盐胁迫下芦苇与碱蓬光合色素含量与叶绿素荧光参数表现出不同的变化规律。芦苇叶片光合色素含…查看全部>>
[Objective]The aim of this study was to clarify the fluorescence characteristics and photoprotection mechanism of Phragmites australis and Suaeda glauca under salt stress.[Method]The pot experiment was conducted with seedlings.The salt concentrations of 0%(control),0.5%(C1),1%(C2),1.5%(C3),2%(C4),2.5%(C5)and 3.5%(C6)were set to measure the photosynthetic pigment contents and chlorophyll fluorescence parameters of P.australis and S.glauca seedlings,with subse…查看全部>>
