Field experiment demonstrated that the maximal content of Sr90 was odserved in assimilative leaves of cabbage while the minimal content of Sr90 was traced in upper leaves. In conductive tissues Sr90 concentration increased insignificantly during the growth season. For assimilative plant parts the discrimination coefficient of Sr90 in relation to calcium was less than1. It was revealed the positive correlative dependence between the contents of calcium, magnesium, stable strontium and manganese in vegetative tissues on the one hand and accumulation of Sr90 by these tissues on the other hand
