Plant relative growth rate (RGR) with live (arbuscular mycorrhizal fungi and soil microbial filtrates) from pastures, coffee plantations and forest fragments

The data was collected from a greenhouse experiment in which 11 plant species (read below) were growth with either sterilized soil, or sterilized soil inoculated with arbuscular mycorrhizal fungi (AMF) or a soil microbial filtrate obtained from three habitats: pastures, coffee plantations, or forest fragments. Please read Pizano et al. 2017 Ecological Applications for details on the methods. Abbreviations of the data file are as follows: Inoculum (St=Sterile, PAMF=AMF from pastures, PFil=soil microbial filtrate from pastures, CAMF=AMF from coffee plantations, CFil=soil microbial filtrate from coffee plantations, FAMF=AMF from forest fragments, FFil=soil microbial filtrate from forest fragments), Species (Bra=Brachiaria brizantha, Cof=Coffea arabica, CecA=Cecropia angustifolia, CecT=Cecropia telealba, Ocr=Ochroma pyramidale, Sol=Solanum aphyodendrum, Jug=Juglans neotropica, Ret=Retrophyllum rospigliosii, Gar=Garcinia madrunno, Gus=Gustavia superba, Sip=Siparuna aspera), Total final dw (total whole plant dry biomass (g)), Root/Shoot (root dry biomass (g)/shoot (stem + leaves) dry biomass (g)), Initial leaf area (total plant leaf area (cm2), RGR (plant relative growth rate (final plant dry weight-initial plant dry weight calculated based on initial leaf area/ days of the experiment)(g/gday)), Days in exp. (days in the experiment; some plants were replaced because they died at the beginning of the experiment)

本数据集采集自一项温室栽培实验，实验中共设置11种供试植物（具体种类详见下文），分别种植于灭菌土壤、接种丛枝菌根真菌（arbuscular mycorrhizal fungi, AMF）的灭菌土壤，以及分别添加3种生境来源的土壤微生物滤液的灭菌土壤中——3种生境分别为牧场、咖啡种植园与森林片段。实验方法细节请参阅Pizano等人2017年发表于《Ecological Applications》的研究论文。
数据文件各字段缩写含义如下：
1. 接种剂（Inoculum）：St=无菌土壤，PAMF=牧场来源丛枝菌根真菌，PFil=牧场来源土壤微生物滤液，CAMF=咖啡种植园来源丛枝菌根真菌，CFil=咖啡种植园来源土壤微生物滤液，FAMF=森林片段来源丛枝菌根真菌，FFil=森林片段来源土壤微生物滤液；
2. 物种（Species）：Bra=臂形草（Brachiaria brizantha），Cof=阿拉伯咖啡（Coffea arabica），CecA=窄叶号角树（Cecropia angustifolia），CecT=远轴号角树（Cecropia telealba），Ocr=轻木（Ochroma pyramidale），Sol=无叶茄（Solanum aphyodendrum），Jug=新热带胡桃（Juglans neotropica），Ret=南美罗汉松（Retrophyllum rospigliosii），Gar=加西尼亚（Garcinia madrunno），Gus=古斯塔维亚木（Gustavia superba），Sip=糙叶西帕伦木（Siparuna aspera）；
3. 总最终干重（Total final dw）：植株全株干生物量（单位：g）；
4. 根冠比（Root/Shoot）：根干生物量（g）与地上部（茎+叶）干生物量的比值；
5. 初始叶面积（Initial leaf area）：植株总叶面积（单位：cm²）；
6. 相对生长速率（RGR）：植株相对生长速率，计算公式为（最终植株干重-初始植株干重）除以（基于初始叶面积估算的初始植株干重与实验总天数的乘积），单位为g/(g·d)；
7. 实验时长（Days in exp.）：实验持续天数；实验初期部分植株死亡后已被替换。
