很多研究抓住关键点就会事半功倍，这就是所谓的科研套路。如在植物-水分关系的研究中有哪些关键点呢，我觉得以下的关键词很重要，脑海经常想想它们的关系以及使用的语境或内在关系对文献阅读和科研效率的提高大有好处。

植物-水分关系：

water use

water use efficiency

water use strategy

water flux: sap flux, sap flow, stomatal conductance to water (leaf g_s, canopy g_s) or CO₂

water balance: water cycling

water relations: plant-water relations; tissue/organ/xylem/soil water relations

hydraulic resistance/function/constraints

plant hydraulics

hydrological cycles

hydraulic process

hydraulic property/architecture

hydrological balance/stress

drought resistance/avoidance/tolerance

hydraulic limits/failure
