摘要
Abstract
To explore the response of rice variety Haidao 86 under saline-alkali stress, the ability of saline-alkali tolerance of Haidao 86 in germination were studied in the experiment under different salt(NaCl), alkali(Na2CO3)and saline-alkali(NaCl-Na2CO3)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(NaCl)stress, which showed Haidao 86 were highly resistant to salt(NaCl);(2)Haidao 86 threshold value of saline-alkali tolerant was 0.30%~0.35%under alkali(Na2CO3)stress,which indicated Haidao 86 were highly resistant to alkali(Na2CO3).(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.关键词
