Notes:
Water uptake rate of decapitated root systems of cotton (Gossypium hirsutum L.), tomato (Lycopersicon esculentum L. cv. Rutgers), and kidney bean (Phaseolus vulgaris L.) plants shows an exponential increase with applied suction up to about —1 bar. The water uptake rate was higher on the descending path of applied suction than on the ascending path, indicating a hysteresis effect in the roots. The root resistance in a cotton plant increased between 3-to 5-fold during the photoperiod of 12 hours. The water uptake rate increased with increasing temperature of the root medium up to 30°C in cotton and 25°C in tomato and bean plants.
