摘要
利用盆栽试验,设置玉米(Zea mays L.)和三叶草(Trifolium repens L.)2种宿主植物和3种培养基质(沙土和农田土质量比分别为1∶1,2∶1和3∶1),研究了宿主植物和培养基质对柠条(Caragana korshinskiiKom.)根围土著AM真菌生长发育的影响。结果表明:宿主植物为玉米,培养基质中沙土与农田土质量比为3∶1时,AM真菌菌根侵染率、孢子密度、根内菌丝琥珀酸脱氢酶活性和菌根长度均为最高。说明以玉米为宿主植物,沙土与农田土质量比为3∶1的盆栽基质对柠条根围土著AM真菌的生长发育最为有利。
The effects of different host plants（Zea mays L. and Trifollum repens L. ）and culture substrates（the mass ratio of sand to soil was 1：1,2：1 and 3：1,respectively）on growth and development of arbuscular mycor- rhizal（AM） fungi in the rhizosphere of Caraganakorshinskii were studied using pot experiment. The results showed that mycorrhizal colonization,spore density,succinate dehydrogenase activity of intraradical hypha and mycorrhizal length were the highest when the host plant was Zea mays under the substrate（mass ratio of sand to soil was 3：1）. Therefore,Zea mays as host plant and culture substrate（mass ratio of sand to soil was 3：1） were the best for the growth and development of indigenous AM fungi in the rhizosphere of C. korshinskii.
