采用盆栽试验法,于2006年7月31日开始,用0.2% NaCl溶液对四季菊、福禄考(Phlox paniculata)、荷兰菊(Aster novi-belgii L.)和大花萱草(Hemerocallis middendorffii)进行盐胁迫处理,每周浇盐液一次,连续浇灌3次,调查试材的盐害情况, 并计算盐害指数.分别于8月7日、8月15日、8月23日测定叶片中脯胺酸、SOD、POD、MDA等生理生化指标的质量分数或质量摩尔浓度,采用频度靠前优先的排序原则进行综合评价.结果表明:在盐胁迫下,4种草本宿根花卉耐盐性强弱为荷兰菊﹥四季菊﹥大花萱草﹥福禄考.

Potted seedlings of Chrysanthemum sp. , Phlox paniculata, Aster novi-belgii and Hemerocallis middendorffii were treated with 0.2% NaCl solution for the first time on July 31st, 2006. In the following two weeks, irrigated the potted seedlings with 0.2% NaCl solution once a week, and then investigated the salt tolerance of the potted seedlings and calculated the salt inju-ry index. The contents of proline, SOD, POD, MDA in the leaves of the potted seedlings were determined on August 7th, August 15th, August 23rd, respectively. A comprehensive evaluation on salt tolerance was made according to the ranking princi-ple of giving top priority to high frequency. Result shows that under salt stress, salt tolerances of four herbaceous perennial flow-ers exhibit Aster novi-belgii, Chrysanthemum sp. , Hemerocallis middendorffii, and Phlox paniculata from high to low.
