Abstract
Alterations of charges density on membranes (potentials) of plant cells by ion currents lead to disbalance of Coulomb forces compressing membranes and counteracting Hookean elastic forces. It should results in membrane vibrations till establishment new equilibrium with generation of ultrasound and electromagnetic radiations. Such vibrations lead to acoustical flows, power of which is sufficient for water lift in trees, its degassing, for cycloses and some electric phenomena in plants and so on. This phenomenon explains the known observations of ultrasound noises in trees and redistribution of particles in the phloem flow. Known supervisions and consideration of anatomy of plants result in estimations of frequencies of the order of 150-200 kHz for acoustical flows in xilem and three times bigger in phloem. The checking of offered mechanism can be carrying out via investigation of acoustic and electromagnetic radiation of plants. Keywords: plant, ultrasound, acoustical flow, hydraulics PACS: 43.25.Nm, 43.38.+n, 43.80.+p, 82.39.Jn, 87.80.Vt
