✦ Synopsis

A plant water stress index has recently been developed which employs a radiometric measurement of foliage temperature and a psychometric measurement of the vapor pressure deficit of the air. To utilize the index, it is necessary to know the relationship that exists between fohage--air temperature differenhal and air vapor pressure deficit for the plant m question when it is well watered and transpiring at the potential rate This informahon is provided for 26 different spemes for clear sky conditions m the format of non-water-stressed baselines For six of these plants, including one aquatic spemes, such informahon is also included for cloudy or shaded conditions, and two grain crops have results presented for both pre-headmg and post-heading growth stages.
