The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.
