以高粱为宿主,采用盆栽试验,研究生化因子对丛枝菌根真菌Glomus intraradices产孢和侵染的影响.结果表明:单一有机氮源和活性物质能显著提高G.intraradices产孢和侵染,酒石酸铵(0.5%)、甘氨酸(1%)和根浸出液(2 mL),可分别使每160 g沙样孢子产量提高至382,302和328个,对照仅为155个;甘氨酸(0.5%1.0%)、酒石酸铵(0.5%)、腐殖酸铵(0.5%,1.0%,2.0%)和根浸出液(2,3,5 mL)处理,可使根侵染率分别提高至53.7%,52.8%,43.9%,59.4%,48.9%,57.7%,64.9%,55.9%,52.9%(对照仅为27.3%);单一碳源(葡萄糖、蔗糖)则对G.intraradices产孢和侵染率都没有显著影响;不同的氮源+碳源(NH4Cl+葡萄糖)组合对G.intraradices产孢和侵染率有不同影响,当C、N比值为4∶1,1∶2时,显著提高G.intraradices产孢,可分别使每20g沙样产孢量可分别达到2227,2458个(对照仅为157个).当C、N比值为1∶2时,侵染率为2.4%,显著低于对照19.3%;比值为4∶1时,对侵染率没有显著影响.生化因子对G.intraradices产孢和侵染的作用特点不同.
