图4 OsRPK1-RNAi水稻在胁迫下生长情况 A: NaCl胁迫前; B: 140 mmol L-1 NaCl胁迫10 d; C: 140 mmol L-1 NaCl胁迫后恢复7 d; D, E: 盐胁迫恢复培养后存活率统计。差异显著性分析采用t-test方法, *P < 0.05、**P < 0.01、***P < 0.001。

Fig. 4 Salt stress tolerance of the OsRPK1-RNAi rice plants A: rice seedling without NaCl stress; B: treated with 140 mmol L-1 NaCl for 10 days; C: recovery for seven days after 140 mmol L-1 NaCl stress; D, E: survival rate after renewing culture under salt stress. The significant difference was evaluated by the Student’s t-test. * P < 0.05, ** P < 0.01, *** P < 0.001.
