The beta-ray gauging technique was used to measure the relative changes occurring in the water content of sour orange and sweet lime leaves as a result of soil wetting and drying cycles. Promethium-147 served as the radiation source and was found suitable for measuring changes in citrus leaf thickness within the range of 20 mg/cm2 (when soil moisture content was at 'pot capacity') to 10 mg/cm2 (when soil moisture dropped to wilting point). By using the correlation between beta-ray gauging measurements, leaf thickness, and relative turgidity, it is possible to determine the status of water in citrus leaves under different soil moisture conditions. © 1968 Oxford University Press.
