- 摘要:
- 以黑农44( 高脂肪品种) 大豆品种作为试验材料,以不同方式在连作大豆根际土壤中接种摩西管柄囊霉( Funneliformismosseae) 和大豆根腐病原菌尖孢镰刀菌( Fusarium oxysporum) 。采用传统形态学方法检测Fu. mosseae 和F. oxysporum侵染大豆植株根系情况。利用实时荧光定量PCR 技术分析Fu. mosseae 和F. oxysporum DNA 含量变化。结果表明: Fu. mosseae 和F. oxysporum 均能侵染大豆植株根系,但接种Fu. mosseae 的大豆植株根系及根际土壤样品中F. oxysporum DNA 含量显著降低,表明Fu. mosseae 对F. oxysporum 具有强烈的抑制作用。本研究为进一步研究AM 真菌克服大豆连作障碍提供了理论依据。
- Abstract:
- In this study,Heinong 44 ( a high-fat cultivar) soybean cultivar was selected as materials. Funneliformis mosseaeand the root rot pathogen Fusarium oxysporum were inoculated into the soybean continuous cropping soil in different treatments.The colonisation rates of Fu. mosseae and disease incidences of F. oxysporum were analyzed statistically,respectively.Quantitative PCR was applied to analyze the DNA content of Fu. mosseae and F. oxysporum. The results showed that both Fu.mosseae and F. oxysporum could infect the soybean roots. However,the DNA content of F. oxysporum clearly decreased insoybean root and rhizosphere soil samples after the inoculation with Fu. mosseae. It might indicate inhibitive effects of Fu.mosseae over F. oxysporum. It provides theoretical evidence on the AM fungi to overcome the obstacles of soybean continuouscropping.
