由于硝酸还原酶(NR)在硝酸同化过程中起着重要作用,人们进行了大量的研究工作,对玉米、小麦、大麦的研究结果均表明NR活性与籽粒及籽粒蛋白质产量相关。近年来的研究表明NR活性与作物的耐肥性呈负相关,并认为这是高等植物的一个普遍规律。肖翊华等对11个杂交水稻组合NR活性的研究认为,NR活性作为优势杂种的预测指标具有很大潜力。本文试图通
Since nitrate reductase (NR) plays an important role in nitric acid assimilation, a large number of studies have been carried out. The results of corn, wheat and barley show that NR activity is related to grain and grain protein yield. In recent years, studies have shown that NR activity and crop resistance is negatively correlated, and that this is a common law of higher plants. Xiaoyi Hua et al. Studies on NR activity of 11 hybrid rice combinations suggest that NR activity has great potential as a predictor of heterosis. This article tries to pass
