Study on the salt tolerance of four wild legumes in Tarim River Basin

The salt tolerance of 4 wild legumes, including Glycyrrhiza inflata, Alhagi sparsifolia, Sophora alopecuroides and Sphaerophysa salsula from Tarim River basin, were evaluated under 5 levels of salt stress (0, 0.4%, 0.8%, 1.2% and 1.6% of NaCl solution) in seed germination period. The result showed that their salt tolerance was different, in which, G. inflata and A. sparsifolia performed the better salt endurance, and followed by S. salsula and S. alopecuroides. The low concentrate salt solution stimulated the seed germination, growth of embryo and radicle to a certain degree. The germination rate declined and the growth of embryo and radicle were inhibited along with the salt concentration increasing.
