| 摘 要： | 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.

| Abstract: | 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 injury index.The contents of proline,SOD,POD,MDA in the leaves of the potted seedlings were determined on August 7th,August 15th,August 23rd,respective... |
