Abstract:
The present greenhouse study was undertaken to evaluate the effects of co-inoculating the ectomycorrhizal(ECM)fungus Pisolithus tinctorius(Pers.)Coker & Couch(Pt2), Lactarius insulsus Fr.(Li)with the mycorrhiza helper bacterium Bacillus sp. DZ18 on the growth of poplar seedlings. After 120 days treatment, ectomycorrhizal colonization rate, shoot length, root crown diameter, root biomass, stem biomass, photosynthesis, and mineral metabolism ability of poplar were measured. The results showed that Bacillus DZ18 coinoculated with Pisolithus tinctorius(Pt2)or Lactarius insulsus(Li)significantly improved mycorrhizal formation rate of poplar compared with a single inoculation Pt2 or Li, and whether single inoculation DZ18 or DZ18 coinoculation with Pt2 and Li, the poplar growth indices were significantly promoted. Therefore, MHB strain DZ18 had potential value to become an excellent bio-fertilizer strain resources.
