| 摘 要： | 以采自菏泽牡丹园的牡丹‘凤丹’为材料,采用盆栽方法研究了不同浓度人工海水（0%、8%、16%和24%）胁迫下,接种丛枝菌根（arbuscular mycorrhizal,AM）真菌Glomus mosseae对牡丹渗透调节物质含量的影响,以不接种为对照。结果表明,盐胁迫下接种AM真菌能提高牡丹叶片可溶性糖和可溶性蛋白的含量,增大K＋/Na＋比值,减少叶片脯氨酸含量。结论认为,AM真菌能改善牡丹叶片的渗透调节,增强牡丹耐盐能力,促进了盐胁迫下牡丹幼苗的生长。

| Abstract: | The effects of arbuscular mycorrhizal（AM） fungi on the tolerance of Paeonia suffruticosa to salt stress（0%,8%,16% and 24%） were studied.Potted ＇Feng Dan＇ seedlings were inoculated with AM fungus Glomus mosseae,and the non-inoculated was used as control.The results showed that AM fungal inoculation promoted the accumulation of soluble sugar and soluble protein in leaves,increased the ratios of K＋/Na＋,but reduced the accumulation of proline.These results suggest that AM fungi may play an important role in the enhanced salt tolerance and growth of treepeony seedlings. |
