| 摘 要： | 采用无土栽培的方法,对20个名贵菊花品种进行了耐盐性筛选试验。结果表明:在浓度为0.6mol/L NaCl胁迫下,以植株所受的盐害指数为依据,可以对名贵菊花的耐盐性进行快速、有效筛选;根据聚类结果将20份材料的耐盐性分为极强、强、中等、弱、极弱5个级别,其中"黄松针"耐盐极强;"紫云"、"千秀银针"等5份材料耐盐性强,"炼丹炉"等9份材料耐盐性中等,"秋水芙蓉"等3份材料耐盐性弱,"彩霞"等2份材料耐盐性极弱。

| Abstract: | Comparison of salt-tolerance for 20kinds of precious chrysanthemum were studied through soilless cultivation method.The results showed that when NaCl concentration was 0.6mol/L in nutrient solution,salt tolerance screening of plants from precious chrysanthemum could be achieved effectively and rapidly by salt injury index of plant.Clustering analysis showed that salt tolerance of 20taxa be divided into extremely strong,strong,medium,weak,extremely weak respectively.‘Huangsongzhen’ were extremely strong salt-tolerance,five taxa represented by ‘Ziyun’ and ‘Qianxiuyinzhen’ were strong salt-tolerance,nine taxa represented by ‘Liandanlu’ were medium salt-tolerance,three taxa represented by ‘Qiushuifurong’ were weak salt-tolerance,two taxa represented by ‘Caixia’ were extremely weak salttolerance. |
