| 摘 要： | 试验研究了在3个氮处理水平上对12个结球甘蓝自交系的氮效率。结果表明,不同结球甘蓝自交系的产量、氮吸收效率、氮生理利用效率、氮效率和氮响应度存在显著的差异。据氮效率分析,把供试结球甘蓝自交系划分为4个类型:92-1041,96-1047,96-1013,606-12-21属于双高效型;96-1025-1,96-1028属于低氮高效型;96-1038-8,92-1023,97-1126属于双低效型;96-1012-3-11,97-1018,PR1-3-6属于高氮高效型。

| Abstract: | Pot experiment with 12 cabbage inbred lines was conducted to study the difference in N efficiency at 3 N levels.The results showed that significant difference existed among inbred lines in yield,N uptake efficiency,N physiological utilization efficiency,N efficiency and N responsiveness.According to N efficiency,cabbage inbred lines can be clarified into four types: 92-1041,96-1047,96-1013,606-12-21 were belong to double high efficiency which presented high yield under both high and low nitrogen rate;96-1025-1,96-1028 were high efficiency only in low N application;96-1038-8,92-1023,97-1126 were belong to double low efficiency which presented low yield under both high and low nitrogen application;96-1012-3-11,97-1018,PR1-3-6 were high efficiency only in high N application. |
