The plant water potential coefficient (measured by the plant moisture status meter and related measurements) is proposed, and the change of plant water potential is determined by the influence of atmospheric water potential and soil water potential. The more unfavorable the environment (higher temperatures or larger soil salinity or less soil moisture), one of the responses to plant adaptation is to show a lower water potential to withstand adverse environmental conditions, at this time atmospheric water potential and soil water potential The smaller the direct influence on the plant water potential, the higher the water potential value that the atmospheric water potential and the soil water potential contribute to the plant water potential, and the measured value of the non-dimensional plant water condition meter is relatively large.
By comparing the value of the plant water condition analyzer, it can be used to measure the strength of the plant response to environmental stress, or to measure the strength of the plant adaptive response. In order to make the plant water potential coefficient has a good representation, a small sample At least 9 observations of atmospheric water potential, plant water potential, and soil water potential should be taken into account during the calculation. In actual research, it is best to perform a large sample analysis. On the other hand, the plant water potential has observations at a certain moment, but there is no plant water potential coefficient, and there is only one calculated value at a certain time.
The water potential of plants is susceptible to changes in external environmental factors and has a certain degree of relativity. In high-temperature months, the response of plants to environmental stress is stronger, while in non-high-temperature months, the response of plants to environmental stress is weaker. Therefore, from From this point of view, the measured value of the plant water condition meter can objectively reflect the environmental impact on the plant and the plant's response to the environment, and thus can be used as an indicator to measure the strength of the plant's response to environmental stress.
