After 18 weeks, elevated CO2 (720 μmol·mol-1) increased significantly the
ectomycorrhizal development. The phosphate concentration (P) in needles of Pinus densiflora and Larix kaempferi inoculated with Pt or EC was significantly higher than that without
inoculation at both CO2 concentrations. Pt or EC inoculation had led to significantly increase the
physiological activities, such as the PAR
saturated net photosynthetic rates (Psat),
maximum net photosynthetic rate at saturated CO2 concentration (Pmax), carboxylation efficiency (CE), RuBP
regeneration rate of A/Ci curve and
water use efficiency (WUE) of P. koraiensis,
P. densiflora and L. kaempferi seedlings grown at both CO2
concentrations (360 and 720 μmol·mol-1) relative to non-inoculated
seedlings. Moreover, dry mass and
stem diameter of inoculated P. koraiensis,
P. densiflora and L. kaempferi seedlings significantly
higher than those non-inoculated seedlings.
