The cross-adaptaition of cucumber seedlings to soil salinity and heavy metalls

Abstract

The consequences of plant cross adaptation on cucumber seedlings and shoots under NaCl, СuSO4 and ZnSO4 influence on life's activiny was studied. Medium salification produced an increase of fluorescence and proline content in leaves, ion disbalance, decrease of survival percentage, accretion and rooting of cuttings. The pretreatment of cuttings and seedlings by NaCl solutions increases their tolerance to subsequent effect of copper sulphate and zinc sulphate.
