Keyword:  海水胁迫"南盐一号"库拉索芦荟离子质膜透性丙二醛含量响应;
Abstract: 考察了4组库拉索芦荟(F0CK、F50CK、F060%、F5060%)叶片的鲜重、干重,叶片内Na+、K+、Mg2+、Ca2+离子的含量以及质膜透性,丙二醛含量.结果表明:同在60%海水(即海水:淡水体积比3:2)胁迫下,F5060%的干湿重比远大于F060%的干湿重比;F5060%叶片内的Na+离子含量显著小于常规芦荟,K+离子含量远高于常规芦荟,F5060%芦荟较F060%拥有更高的K+/Na+和更低的Na+/Ca++;芦荟叶片的质膜透性显著上升,丙二醛含量也有小幅度上升,但F50上升幅度都较F0小.可见,F50库拉索芦荟较F0库拉索芦荟在抗海水胁迫能力上有一定程度的提高.
