SUSTAINABILITY OF THE POPULUS L. FAMILY TO SALINIZATION BY SODIUM CHLORIDE
The paper deals with the problem of sustainability of three varieties of poplar family: Populus Nigra L., P. balsamifera L., P.pyramidalis Roz. to sodium chloride salinization. Salt sustainability of green and lignified cuttings in sand and liquid substrates under different concentrations of salinization has been studied. Increased salt resistance in the introduced P. balsamifera L. variety is pointed out.
