Rapid effect of enriched N at R1 stage on sucrose metabolism of soybean. Compared with CLN treatment, after enriched N at R1 stage, the SS activity of leaf was increased first and then decreased. However the SS activity of root was decreased first and then increased. The GmSS5 expression in leaf and GmSS1 expression in root was up-regulated. Means compared with CLN treatment, the enzyme activity and gene expression have no significant changes.
