【目的】探索盐土条件下不同藜麦品系花期遭受渍水胁迫的响应机制，促进沿海地区藜麦的引进、选育和推广种植。【方法】选取4个藜麦品系（SL 21、SL 44、SL 24和SL 45），采用盆栽实验，以不渍水为对照（CK），研究了盐土环境下藜麦花期对不同渍水持续时间（4、8和12 d）的生理特性和产量构成响应，并明确了排水指标。【结果】盐土条件下，随着渍水时间的增加，4个品系藜麦叶片的丙二醛（MDA）物质的量浓度呈增加趋势，叶绿素Chl(a+b)量、可溶性蛋白（SP）量、可溶性糖（SS）量、光合指标参数（Pn、Tr、Gs、Ci）和叶绿素荧光参数（Fv/Fo、Fv/Fm）均呈降低趋势。渍水4 d后，4个品系藜麦叶片MDA物质的量浓度显著均高于CK，SL 21和SL 24的Chl(a+b)量和SS量显著...
