摘要:
采用12种外生菌根真菌接种I69杨、I72杨和小叶杨后,发现劣味乳菇(Lactarius insulsus)、红绒盖牛肝菌(Xerocomus chrysenteron)与3种杨形成菌根化率均大于50%,且可以显著促进3种杨的苗高生长,为较广谱的优良外生菌根真菌。接种南林895杨的6种菌根真菌中,红绒盖牛肝菌(Xerocomus chrysenteron)、劣味乳菇(Lactarius insulsus)、美味牛肝菌(Boletus edulis)可促进南林895杨扦插苗提早萌芽,处理120 d后能显著促进南林895杨苗的生长,与对照比较差异显著,其中劣味乳菇对杨苗生物量影响最大,其接种试验苗根系最为发达。菌根真菌均在南林895杨根系表面形成菌丝套和哈缔氏网结构,并可以显著促进宿主的须根萌生并增加植物根系的质量。
Abstract:
Cottonwood clone 69, clone 72, and Simon poplar, were inoculated with 12 ectomycorrhizal fungi, respectively. Experiment results indicated that Lactarius insulsus and Xerocomus chrysenteron were elite ectomycorrhizal fungi, which led more than 50% ectomycorrhizal infection and evidently promoted seedling height of the tested three poplars. We also inoculated cottonwood clone 895 with 6 ectomycorrhizal fungi. It was found that Xerocomus chrysenteron, Lactarius insulsus and Boletus edulis accelerated seedlings generation from cuttings of clone 895 more than the other fungi did, and they remarkably promoted seedling growth comparing with the control. Lactarius insulsus promoted aboveground biomass and root system most effectively. All kinds of ectomycorrhizal fungi formed mycorrhizal mantle and hartig net structure. These fungi facilitated the fine root germination, and enhanced growth increment of root system.
