To explore the response of rice variety Haidao 86 under saline-alkali stress, the ability of saline-alkali tolerance of Haidao86 in germination were studied in the experiment under different salt(NaCl), alkali(Na_2CO_3)and saline-alkali(NaCl-Na_2CO_3)mixed stress, with rice variety Huanghuazhan as control. The results showed that:(1)Haidao 86 threshold value of saline tolerance was 0.9%~1.0% under salt(Na Cl)stress, which showed Haidao 86 were highly resistant to salt(NaCl);(2)Haidao 86 threshold value of salinealkali tolerant was 0.30%~0.35% under alkali(Na_2CO_3)stress,which indicated Haidao 86 were highly resistant to alkali(Na_2CO_3).(3)Haidao 86 threshold value of saline-alkali tolerant was A2(0.8%)B2(0.15%)~A2(0.8%)B3(0.25%) under saline-alkali mixed stress, and interaction effect of saline-alkali was significant on this study conditions.
