Abstract:
Taking Trifolium repens new strain (‘Z005’) as material，the effect of different concentration (0,20,40,80,120,160,200 mmol/L)saline-alkaloid (NaCl,Na2SO4,NaHCO3,Na2CO3)stress on the seed germination and seedling growth of Trifolium repens new strain (‘Z005’) were studied.The results showed that low concentration of saline-alkaloid stress(concentration was≤20 mmol/L) could improve seed germination ability and seedling growth of Trifolium repens，contrastly，high concentration decreased seed germination and seedling growth.When the concentration was exceed 80 mmol/L，germination rate，germination potential，germination index，vigor index，root length and shoot height were significantly lower compared with control (P<0.01). Seed of Trifolium repens could germinate under the condition that the concentration of saline-alkaloid below 94.50 mmol/L.And saline-alkaloid stress had a higher inhibition to root length than shoot height.
