The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity.
At the other extreme, Salicornia bigelovii (dwarf glasswort) grows well at 70 g/L of dissolved solids, and is a promising halophyte for use as a crop.
[6] Plants such as barley (Hordeum vulgare) and the date palm (Phoenix dactylifera) can tolerate about 5 g/L, and can be considered as marginal halophytes.
Halophytes such as Salicornia bigelovii can be grown in harsh environments and typically do not compete with food crops for resources, making them promising sources of biodiesel or bioalcohol.
[6][8][9] Halophytes like Suaeda salsa can store salt ions and rare-earth elements absorbed from soils in their tissues.
[11] These measures aim to allow glycophytes to survive in previously uninhabitable areas through an environmentally safe, and cost effective process.
