摘要 外源一氧化氮供体硝普钠浸种可以提高玉米种子的发芽率,浓度为10、100、1 000、2 000 mol.L-1时,促进幼苗地上部和根的伸长生长,且有利于玉米侧根发生,幼苗叶片中的硝酸还原酶的活性也提高。以100 mol.L-1的硝普钠处理的综合效果最好。 Exogenous nitric oxide (sodium nitroprusside, SNP), with 10, 100, 1 000, 2 000 mol.L-1 couldincrease the germination rate and promote growth of root and aerial part. At the same time, it also induced moreroots and improved the activity of nitrate reductase (NR). The effect of 100 mol.L-1 SNP was best.
