摘要： 在PDA、KB和含Fe+++的KB琼脂平板上,Pseudomonas sp. A03和Rhizoctonia solalni之间出现抑菌带。Pseudomonas sp A03培养物的无菌滤液及其粗提物以及在KB平板上产生的挥发性抗生物质都能抑制Rhizochtoni asloani菌丝生长。电镜扫描发现A03在杉木和云杉幼苗根面定殖。

Abstract: Clear zones between Pseudomonas sp.A03 and Rhizocto niasolani appeared in such agar media as PDA, KB and KB containing Fe+++, the growth inhibition of R. sclani mycelium was caused by both cell-free filtrates and rough extracts of Pseudomonas sp.A03 grown in shake culture, and also by their volatile antibiotics produced in KB culture plate.Scanning electron microscope showed that A03 colonized on the root surface of china fir and spruce seedlings.
