Xylem vulnerability curves of canopy branches of mature trees from Caxiuana and Tapajos National Forests, Para, Brazil

Included in this data package are raw data for xylem vulnerability curves measured on upper canopy branches of mature trees from the Caxiuana and Tapajos National Forests, Para, Brazil. Tapajos samples were harvested from km67 transects, which is nearby the decommissioned throughfall-exclusion, drought-experiment plots. Caxiuana samples were harvested from trees growing in the throughfall-exclusion, drought-experiment plots. Data were collected in 2011 and 2012. The CSV dataset attached includes: date of measurement, site ID, plot ID, tree ID (species, tree tag #), xylem pressure, percent loss of conductivity. Air injection method was used.

本数据包收录了巴西帕拉州卡舒埃纳（Caxiuana）与塔帕若斯（Tapajos）国家森林内成熟树木冠层上部枝条的木质部脆弱性曲线（xylem vulnerability curves）原始测量数据。其中塔帕若斯的样品采自km67样带，该样带邻近已停运的穿透雨截留干旱实验样地；卡舒埃纳的样品则采自穿透雨截留干旱实验样地内生长的树木。
数据采集工作于2011年与2012年完成。附件中的CSV数据集包含以下字段：测量日期、样地编号、样方ID、树木ID（含物种信息、树木标签号）、木质部压力、导水率损失百分比。本次测量采用空气注入法。
