Abstract:
Taking Vigna unguiculata (Linn.) Walp.‘Jiadouwang’ as test material，the effects of NaCl stress on early growth and seed size and its interaction on seed germination and seedling growth were studied.The results showed that NaCl stress significantly affected seed germination rate，root length，shoot length and fresh weight of Vigna unguiculata (Linn.) Walp.It had less effects on corn seeds germination when the density of NaCl solution was less than 50 mmol/L，but had significantly inhibited when the density was over 50 mmol/L and the seed germination was entirely suppressed when the density of NaCl solution was 150 mmol/L.The root length and shoot length showed a significant inhibition in all of the NaCl concentration，however，the germination rate and fresh weight of the seedlings had significantly inhibited when the density of NaCl solution was over 50 mmol/L.Seed size on root length and shoot length was not significantly affected，but a significant impact on the germination rate and fresh weight of seedlings.Interaction between NaCl stress and seed size on germination rate，root length，shoot length and fresh weight did not significantly affect.
