摘要: Trichoderma harzianum FO60菌株产生的代谢物质能抑制Rhizoctonia solani的菌落生长和降低其菌丝干重,其中非挥发性代谢物具热稳定性。光学显微镜和扫描电镜下,发现PO60菌丝在R. Solani菌丝上平行或波浪式生长,并在其上形成附着胞或钩状分枝,有溶解和穿入R. solani菌丝,R. solani菌丝断裂和原生质发生颗粒状变化的现象。

Abstract: The antibiotics produced by Trichodrrma harzianum (FO60) inhibited both mycelia growth and sclerotial formation of Rhizoctonia solani.Non-volatile antibiotics were not susceptible to the heating.Hyphal interactions beween T. harzianum and R. solani were observed by microscopy and scanning electron microscopy.The mycoparasite attached to the host fungus by hooks and appressoria.Lysed and penetration sites were found in hyphae of the host fungus.
