The effect of 2,4-dinitrophenol on the absorption and translocation of calcium by pumpkin plants

  • Olga Votrubová-Vaňousová


The study deals with the absorption and translocation of Ca2+ by án intact plant of pumpkinCucurbita pepo L. and with the effect of various concentrations of 2,4-dinitrophenol (DNP) on these processes. The absorption of Ca2+ was reduced by the application of this inhibitor, but not completely stopped. The translocation of Ca2+ into shoots was affected more expressively: it was almost completely inhibited by higher DNP concentrations. The uptake of Rb+ is aubstantially more influeneed than that of Ca2+: higher inhibitor concentrations caused its complete cessation.
