WebSep 1, 2001 · Abstract. A pressure chamber and a root pressure probe technique have been used to measure hydraulic conductivities of rice roots (root Lp r per m 2 of root surface area). Young plants of two rice (Oryza sativa L.) varieties (an upland variety, cv. Azucena and a lowland variety, cv. IR64) were grown for 31–40 d in 12 h days with 500 … WebThe effects of root pressure can be seen only during the night and early morning as the rate of evaporation is very low. The main contribution of the root pressure is to establish the continuous movements of the water …
