Plant-mycorrhizal interactions differ between past low CO2 conditions and current CO2 concentrations

Data set containing measurements of biomass, AM inoculation, photosynthetic rates, and dark respiration rates. The corresponding manuscript is being submitted and further information will be added later.本数据集包含生物量、AM接种（Arbuscular Mycorrhizal inoculation）、光合速率及暗呼吸速率的测定数据。相关研究稿件已投稿，后续将补充更多相关信息。
