| Abstract: | [ Objective ] The research aimed to study the effect of NaCl solution on seed germination of Vaccaria segetalis. [ Method ] The effect of different NaCl level on physiological index of seed germination of Vaccaria segetalis was examined by culture dish treatment. [ Result ] The germination rate, germination potential and germination index of Vaccaria segetalis declined with the increase of NaCl level, while the relative salt injury rate was positively correlated with NaCl level. [ Conclusion]The seed of Vaccaria segetalis exhibited a certain salt tolerance;0.7% NaCI was the maximum salinity on seed germination. |
