摘  要:
采用0、50、100、150、200、250 mmol/L的NaCl溶液处理2个油菜品种(四月蔓和大江束腰)5 d,研究在不同盐浓度处理下发芽势、发芽率及萌发活力指数等指标。结果表明:2个油菜品种的发芽势、发芽率及萌发活力指数等指标随盐浓度的增加而呈下降趋势,盐浓度高于100mmol/L的发芽率、发芽势明显下降,下降程度的差异说明耐盐性的不同。随盐浓度的增加油菜种子的萌发时间延长,萌发整齐度下降;品种不同,萌发时间和萌发整齐度不同。

摘  要:
Use the NaCl solution of 0,50,100,150,200,250 mmol/L to deal with two rapeseed varieties(si yue man and da jiang shu yao) for five days,study,under different concentrations of salt germination energy,germination percentage and germination index and other indicators of vitality.The results showed that the two varieties of oilseed rape germination energy,germination percentage and vigor index and other indicators of germination with the increase in salt concentration is declining,was higher than 100 mmol/L of the germination rate,germination potential decreased significantly.Note the difference in decline in the level of the different salt tolerance.With the increase in the concentration of rape seed germination time,germination uniformity declining species germination time and germination of different degrees in different rows.
