为探讨功能微生物对镉(Cd)胁迫下蒌蒿耐受性的影响,以成团泛菌(Pantoeaagglomerans)J2为对象,通过盆栽试验,研究不同Cd处理水平下J2菌对蒌蒿生长、生理、Cd富集转运与根际微生态的影响。结果表明:J2菌可显著促进蒌蒿株高、地上部干重、地下部干重、总生物量及根冠比的增加。在J2菌的作用下,蒌蒿叶绿素a、叶绿素b和总叶绿素含量以及超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性均显著增加,丙二醛(MDA)含量明显减少。J2菌可显著促进蒌蒿对Cd的富集转运,蒌蒿地上部、地下部与总Cd含量均显著增加,地上部生物富集系数(BCF)明显大于地下部,转运系数(TF)相比于对照增加了7.5%~37.4%。J2...

To explore the effects of functional microorganism on Artemisia selengensis tolerance under cadmium stress, this study examined the effects of strain J2 on growth, physiology, cadmium concentration and translocation, rhizosphere micro-ecology of Artemisia selengensis under different concentrations of cadmium by pot experiment. The results indicated that Pantoea agglomerans J2 distinctly enhanced the plant height, shoot dry weight, root dry weight, the total dry weight and root-shoot ratio of Artemisia selengensis under cadmium stress. Strain J2 distinctly increased the contents of chlorophyll ...
