- 摘要:
- 为明确玉米制种田亲本氮素环境对子代苗期生长的调控作用，以氮高效品种吉单27（亲本四287、四144）和氮低效品种四单19（亲本四444、Mo17）为试验材料，设置00N（纯氮 0 kg·hm-2）、10N（150 kg·hm-2）、20N（300 kg·hm-2）3个亲本施氮水平，收获果穗后通过沙培试验（无氮、3叶1心期恢复供氮），分析种子特性及子代苗期生长与氮代谢相关酶活性指标。结果表明，吉单27百粒重随亲本施氮量增加而显著提升，20N处理较00N处理高12.80%，但00N处理种子发芽率最高（91%）；四单19百粒重随亲本施氮量呈先升后降趋势，10N处理发芽率最优（87%）。子代苗期表现出显著品种差异，吉单27呈现“亲子施氮协同响应”特征，无氮条件下00N处理子代植株干物质量较20N处理高26.92%，硝酸还原酶（NR）活性显著高于其他处理；恢复供氮后10N处理子代NR 活性最优[52.85 μg·(g·h)-1]，较00N处理提升91.14%。四单19以10 N亲本的子代植株干物质量最高，恢复供氮后根长明显增大，但氮代谢酶［硝酸还原酶(NR)、谷氨酰胺合成酶(GS)］未表现出协同响应特征。综上，不同氮效率玉米对亲本氮素环境的响应差异显著，吉单27受亲本施氮“记忆调控”效应明显，四单19响应不显著。
