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: <i>Populus Nigra L., P. balsamifera L., P.pyramidalis Roz. t</i>o 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 <i>P. balsamifera L. variety </i>is pointed out.
