Abstract

The effect of nitrogen on growth and nitrogen metabolism of Allium fistulosum L. was investigated to clarify the role of N in affecting the quality, and provide a theoretical basis for the optimization fertilization technique. Three nitrogen levels were tested in the experiment, namely total nitrogen, half nitrogen and free nitrogen. By measuring the activities of enzymes related to nitrogen metabolism in Allium fistulosum L. at four growth stages, the results showed that nitrate reductase (NR), glutamate synthetase (GOGAT) and glutamate dehydrogenase (GDH) had the highest activity in vigorous growth stage with half nitrogen supply. The activity of Glutamine synthetase (GS) was the highest in the vigorous growth stage. With the increase of nitrogen level, The contents of soluble sugar, vitamin C increased first and then decreased. The contents of nitrate, pyruvic acid and free amino acids showed an increasing trend with the increasing of nitrogen level.
