The Influence of Salt Stress on Seed Germination of Southern Xinjiang Wild Solanum nigrum L.

With Solanum nigrum L.and red fruit Solanum nigrum L.as materials,different concentration of NaCl,KCl,Ca(NO3)2 on the influence seed germination were stdied.The results showed that NaCl,KCl solution in low concentrations had promote role on the seed gemination of two kinds of Solanum nigrum L.The Ca(NO3) 2 solution in low concentrations had no role in promoting;and the effect of seeds inhibition of three kinds of salt was KClNaClCa(NO3)2.The concentration of lethal concentration of Solanum nigrum L.were 400~450 mmol/L,red fruits Solanum nigrum L.lethal concentration was 300~350 mmol/L;in the high concentration of salt stress,Solanum nigrum L.had greater germination rate than red fruits Solanum nigrum L.,it showed that the Solanum nigrum L.had stronger resistance.
