abstract:
The aim of this work was to estimate the effect of increased salt level on the production of fresh and dry matter and accumulation of Na+, K+, Ca2+, Mg2+, Cl- ions in dry matter in Amaranthus paniculatus cvs. Copper Moutain and Monarch, Amaranthus caudatus cv. Pony Tails, Atriplex hortensis cv. Green Spire and Tamarix tetrandra. Results of two-year pot experiment performed under controlled greenhouse conditions showed that salt treatment significantly affected all studied parameters. Along with increased salt level, a decrease of fresh and dry weights and an increase of accumulation of Na+, Cl-, Ca2+ were recorded. Studied species/cvs significantly differed in tolerance to salt stress.
