title: [Effects of elevated CO2 concentration on rhizosphere soil microbes under Pinus koraiensis and Pinus sylvestriformis seedlings].
abstract: The study showed that under Pinus sylvestriformis seedlings, the amount of rhizosphere soil bacteria, but not fungi and actinomyces, increased significantly (P < or = 0. 001) with CO2 enrichment (700 and 500 micromol x mol(-1)), and the same (P < or = 0.001) was under Pinus koraiensis seedlings, with the exceptions of 700 micromol CO2 x mol(-1) in August and 500 micromol CO2 x mol(-1) in July, compared to the ambient chamber and the ambient in each month. No significant effect of elevated CO2 was found on the amount of rhizosphere soil fungi except in September ( P < or = 0.001), and the response of actinomyces to elevated CO2 was also insignificant.
