The mechanism, or hypothesis, of how a plant might be adapted to drought should strongly influence experimental design. For instance, an experiment testing for water conservation should be distinct from a damage-tolerance evaluation. We define here four new, general mechanisms for plant adaptation to drought such that experiments can be more easily designed based upon the definitions. A series of experimental methods are suggested together with appropriate physiological measurements related to the drought adaptation mechanisms. The suggestion is made that the experimental manipulation should match the rate, length, and severity of soil water deficit (SWD) necessary to test the hypothesized type of drought adaptation mechanism.
植物适应干旱的机制或假说应该强烈影响实验设计。例如，测试节水的实验应该与耐损伤评估不同。我们在这里定义了植物适应干旱的四个新的一般机制，以便可以根据定义更轻松地设计实验。本文提出了一系列实验方法以及与干旱适应机制相关的适当生理测量方法。建议实验处理应与测试假设的干旱适应机制所需的土壤水分亏缺（SWD）的速率、长度和严重程度相匹配。
