title: [The effect of melamine salt of bis(oxymethyl)phosphinic acid (melafen) on the growth processes and cytoplasmic membrane function in potato tuber cells].
abstract: The effects of a new synthetic growth regulator, preparation melafen, on the growth processes in potato plant tubers and the H+ -ATPase activity in cell plasmalemma were studied. It was demonstrated that melafen could both stimulate and inhibit the growth of potato tubers depending on its concentration and the physiological state of the tubers. It is likely that one of the manifestations of melafen action is its influence on the division and extension of apical meristem cells. The growth stimulation caused by melafen is connected with modifications of the plasmalemma of potato tuber cells, namely, the activation of H+ -ATPase and increase in the membrane proton permeability.
