摘要: Pedunculate oak (Quercus robur L.) was germinated and grown at ambient CO2 level 650 ppmv in the presence absence of ectomycorrhizal fungus Laccaria laccata for a total 6 month under nutrient non-limiting conditions. Mycorrhization elevated atmospheric each supported growth trees. Stem height, stem diameter, dry matter accumulation pedunculate were increased by mycorrhization. Elevated enhanced fresh weight weight, as well lateral root formation In combination, mycorrhization had more than additive, positive effect on tree height biomass accumulation, further improved From these findings it is suggested that efficiency roots supporting shoot mycorrhized trees CO2.
