ĐÁNH GIÁ KHẢ NĂNG LOẠI BỎ MUỐI TRONG NƯỚC NHIỄM MẶN BẰNG CÂY SAM BIỂN (SESUVIUM PORTULACASTRUM L.)

Abstract

In this study, the desalination ability of Sesuvium portulacastrum L. was evaluated via a hydroponic
experimental system with different salinities of 0‰, 10‰, 20‰ and 30‰. The effect of salinity on the
growth of Sesuvium portulacastrum L., its desalination ability, and the accumulation of salts in plant tissues
were investigated. The results showed that, the higher the salinity concentration, the more Sesuvium
portulacastrum L. grew and the more salts it accumulated, especially in the leaves. The desalination ability
of Sesuvium portulacastrum L. was reported to be in the range of 52.29% and 73.23% corresponding to
salinity concentrations ranging from 10‰ to 30‰. These data illustrate the potential application of
Sesuvium portulacastrum L. in desalination.
