在所有关于水分亏缺对植物功能影响的研究中，都需要对处理方法及其对植物水分状况的影响进行准确和全面的定义。回顾了植物和土壤科学中使用的各种水状况测量方法，并回顾了它们对于不同目的的适用性，例如研究水分亏缺对植物的机械影响、耐旱植物的育种或灌溉系统的管理。一个重要的结论是，经常强调水势而不是细胞膨压可能会产生误导，叶子的测量也是如此。概述了当前省略必要的水状态测量的趋势的缺点，尤其是在更多分子研究中常见的缺点，并对特定类型实验的最小测量集提出了建议。
In all studies of the effects of water deficits on plant functioning there is a need for an accurate and comprehensive definition of treatments and their effects on plant water status. The various measures of water status used in plant and soil science are reviewed and their appropriateness for different purposes such as for studies of mechanistic effects of water deficits on plants, for breeding of drought-tolerant plants, or for management of irrigation systems are reviewed. An important conclusion is that the frequent emphasis on water potential rather than on cell turgor can be shown to be misleading, as can be measurements in the leaf. The disadvantages of the current trend towards the omission of necessary water-status measurements, especially common in more molecular studies, are outlined, and recommendations made for minimal sets of measurements for specific types of experiments.
