Effects of Waterlogging and Salinity on Growth and physiology of Kandelia candel and Bruguiera gymnorrhiza seedlings

Abstract

通过室外自动控制模拟潮汐盆栽装置试验,研究了水渍和盐渍胁迫下秋茄(Kandeliacandel)和木榄(Bruguieragymnorrhiza)的生长和生理特性。设计3个盐度水平:5、15、25,用S1、S2、S3表示。设计3个淹水水平:长期淹水(W:Waterlogged),中水位(M:Meanwater),高水位(H:Highwater)。共9个处理:MS1、MS2、MS3、HS1、HS2、HS3、WS1、WS2和WS3。培养期572d。分析探讨了水渍、盐渍以及水渍盐渍联合效应对秋茄和木榄生长、生物量分配、光合作用、丙二醛(MDA)含量、超氧化物歧化酶(SOD)活性、过氧化物酶(POD)...Tropical coastal forests-mangroves-will be one of the first ecosystems to be affected by altered sea levels accompanying global climate change. Responses of mangrove forests to changing sea levels depend on reactions of individual plants. Waterlogging and salinize are two most obvious influences of relative sea level rising to coastal ecosystems. In this paper, Kandelia candel and Bruguiera gymnor...学位:工学硕士院系专业:海洋与环境学院环境科学研究中心_环境工程学号:20023402
