Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by … Meer weergeven Many different factors may affect the total water potential, and the sum of these potentials determines the overall water potential and the direction of water flow: where: Meer weergeven 1. ^ Taiz; Zeiger (2002).
