During daytime when stomata are open, transpiration pull becomes the major driving force in the movement of water in the xylem. During the day the root pressure becomes much smaller than the rate of transpiration. Hence its efficiency decreases during the day. But at night, transpiration is negligible. Hence effect of root pressure in transport of water is more important at night.
