Research Abstract |
We studied the carbon allocation of deciduous trees infected with microbes in soils and greenhouse gas (CO_2 and CH_4) emission rates under a free air CO_2 enrichment (FACE) as affected by soil fertility and simulated tropospheric ozone (O_3). Root growth and microbes' infection of birch were clearly inhibited by O_3 with an open top chamber method. Although plant defense was enhanced by elevated CO_2 but slightly reduced with high soil fertility. At high CO_2, rate of CO_2 efflux increased and CH_4 absorption rate was reduced. Moreover, number of species of collembolan with high mobility was tended to be abundant at high CO_2 treatment with thick litterfall accumulation.
