PG - 393-6 AB - Synthetic growth regulator melafen (10(-5)-10(-10) M) was tested for an effect on the Ca2+ accumulation in plasma membrane vesicles (PMVs) isolated from potato Solanum tuberosum L. tubers at forced rest and sprouting. Melafen proved to regulate the Ca2+ accumulation in PMVs by changing the activity of Ca2+, Mg(2+)-ATPase of the plasma membrane, while no effect was observed with respect to Ca2+ outflow from vesicles. The melafen effect on Ca2+, Mg(2+)-ATPase activity depended on the physiological condition of tubers and the melafen concentration.
