High metabolic sensitivity to hot drought in two declining pine species with constrained physiology

This dataset includes metabolic data and different functional traits of two different pine species including trees in decline and healthy trees. One dataset includes all different shared metabolites identified in the two species and individuals sampled under peak drought stress. The second dataset includes functional traits from gas exchange, hydraulics and osmotic relationships. These functional traits were assessed during two study years with contrasting summer drought.

本数据集包含两种松树（衰退木与健康木）的代谢数据与各类功能性状数据。其中第一份数据集涵盖在干旱胁迫峰值期采样的两个物种个体中鉴定出的所有共有代谢物；第二份数据集则包含气体交换、水力特性及渗透关系相关的功能性状，这些性状在两个夏季干旱条件迥异的研究年度中完成测定。
