Abstract
A method employing the use of both a hanging water column and a field type thermocouple psychrometer was developed to control and measure water potential gradients in pepper plants with confined root systems. Small soil containers were constructed with Millipore filters arranged so that they confined the root system but allowed water transport to the roots. Hydrostatic pressures in leaf petioles were in agreement with those found in the plant top and agreed well with the psychrometerically determined root zone water potential measurements. (Author)
