摘要
随着外生菌根研究的不断深入,越来越多的菌根工作者开始注意到了外生菌根真菌生理活性物质研究的重要价值。T.Santoro et al.,G.N.Krywolap et al.,D.H Marx等先后研究了外生菌根菌在各种培养条件下产生拮抗活性物质及这些拮抗物的理化性质和生物学功能,证明了外生菌根具有生物防治效应的部分原因是由于真菌抗生素的分泌。80年代以来,发现外生菌根及其真菌产生的植物激素在形成菌根及促进寄主植物生长方面起重要作用。如J.H.Graham et al.
Gas chromatography (GC) and High-pressure liquid chromatography (HPLC) were used to detect the phytohormones produced by Boletus sp. and Suillus grevillei. Both fungi could produce ethylene and zeitin but had differences in metabolic activities, and B. sp. could secrete zeitin out of hyphal cell but S. grevillei could not do so.
In the bioassay of antibiotic activity using 4 ectomycorrhizal fungi, Boletus griseus and Laccaria amethystea demonstrated their ability to produce intracellular antibiotics against Rhizoctonia solani.
