[Calixarenes: effects on energy exchange in plant tissues].

The distinctive features of the influence of synthetic compounds of a new class, calixarenes, on the energy exchange of the plant tissues and on the ionic permeability of the plant membranes were investigated. Calixarenes of the different chemical structure were shown to sufficiently influence the oxygen consumption by wheat roots, pH of the incubation mixture, and the potassium ions release. Aminomethylated calyx[4]resorcinaren showed the highest effect. The influence of these compounds on the wheat roots was pH dependent.
