Effects of arbuscular mycorrhizal colonization on the biomass and bioenergy production of Populus × canadensis ‘Neva’ in sterilized and unsterilized soil

摘要: Arbuscular mycorrhizal (AM) symbiosis can improve the growth of poplar, which is considered to be a bioenergy feedstock and substitute for fossil fuels. Microbes in plant rhizosphere may affect interaction between AM fungi host plant. The role on biomass production poplar presence or absence other soil microorganisms was less investigated. In this study, effects Rhizophagus irregularis Glomus versiforme growth, root-absorbing area, chlorophyll content, gas exchange, total organic carbon (TOC) gross calorie value (GCV), lignin cellulose content Populus × canadensis ‘Neva’ sterilized unsterilized were evaluated. results showed that increased parameters such as stem length, ground diameter, dry weight, exchange capacity, well TOC GCV seedlings, but did not content. extent enhancement varied within species conditions. effect higher than soil, function R. greater G. lower soil. general, exhibited applying potential poplar.
