| 摘 要： | 试验研究了不同施氮水平对春玉米根部谷氨酰胺合成酶活性及产量的影响。结果表明,根部谷氨酰胺合成酶活性呈双峰曲线(除丰禾10N100、N200处理外)变化趋势,峰值分别出现在孕穗期和灌浆期。3个品种的N200处理在整个生育过程中谷氨酰胺合成酶活性较高。

| Abstract: | This research focused on the effect of different nitrogen levels on the GS activity in roots and yield of maize. The results showed that except the treatment of N100 and N200 in Fenghe10, the dynamics of GS activities in the roots showed double-peak curve, the peaks appeared at rooting and grain stages. The GS activity of the treatment N200 was high in the growth stages among the three varieties. |
