摘要：

为探究AM真菌参与垂穗披碱草间防御信号介导的抗虫机制，本研究设计了4个处理，分别为A：有菌丝和根连接、B：有菌丝连接无根连接、C：无菌丝和根连接、D：旋转后无菌丝和根连接。于分蘖期进行试验，测定菌根侵染率，收集和分析虫害后挥发物的嗅觉行为反应。结果表明：各处理间差异显著，且对蝗虫有一定的负趋性；有菌丝连接比无菌丝连接的植株产生的挥发性物质（Volatile organic compounds Vocs）含量和种类多；蝗虫采食供体垂穗披碱草诱导受体产生的有效成分包括（E）-2-己烯-1-醇（（E）-2-hexen-1-ol）、芳樟醇（Linalool）、十四烷（Tetradecane）、香芹酚（Carvacrol）、苯甲醛（Benzaldehyde）、石竹烯（Caryophyllene）等物质。证明AM真菌可作为垂穗披碱草株间交流的通道。

Abstract:

To study the effect of arbuscular mycorrhizal fungi (AMF) on Elymus nutans plants defense reactions, We set 4 treatments, A:No barrier, root and hyphal contact; B:Static 40 μm mesh core, hyphal contact, no root contact; C:Rotated 40μm mesh core, Initial hyphal contact broken, no root contact; D:0.5 μm mesh core, no hyphal contact, no root contact. In the tillering stage, the mycorrhizal colonization of receptor plants was tested, the Volatile orgniac compounds (VOCs) in different treatments were collected, and the selective responses of asiatic migratory locust adults to different VOCs were tested as well. The results showed that there were significant differences among the treatments which had some negative taxis to locusts; the species and percentage of the VOCs in which had hyphal contact were higher than in which no hyphal contact; the effective ingredients for insect resistant, came from receptors when locusts eat donors, included (E)-2-hexen-1-ol, Linalool, Tetradecane, Carvacrol, Benzaldehyde, Caryophyllene, and so on. The results proved that Common mycelial networks could be the communicated bridge of Elymus nutans.
