Модификация атразином и симазином ион-селективных свойств плазмалеммы клеток Nitella flexilis
Using electrophysiological approaches to research of ion-selective properties of plasmalemma, change of coefficient Na7K+-selectivity (a) of plasmalemma of Nitella flexilis cells at presence s-triazine herbicides atrazine and simazine is established. It was shown that the increase a at presence 2,3-...
