| 摘 要： | 以耐盐指数、相对生长率和相对叶绿素指数为指标,在组培条件下对5种野生百合21份百合材料进行耐盐性评价,利用各指标的隶属函数值对所有材料进行聚类分析.结果表明,不论从耐盐指数、相对生长率,还是从相对叶绿素指数来看,供试百合材料间的耐盐性差异都达极显著水平.从整体上看,宜昌百合、卷丹与野百合耐盐性较强,山丹次之,宝兴最弱....

| Abstract: | Salt tolerance of five Lilium species in vitro seedlings was evaluated by salt-resistance index,relative growth rate and relative chlorophyll index.Then all the tested materials were cluster analyzed through subordinate function value of each index.Results indicated that salt tolerance among tested Lilium species were of highly significant difference in salt-resistance index,relative growth rate and relative chlorophyll index.In general,Lilium leucanthum Baker,L.brownii,L.lancifolium had relatively strong s... |
