Soyabean stem in vivo nitrate reductase activity
1985
Hunter, W.J.
Stem from three- and four-week-old Soyabean [Glycine max (L.) Merr. cv. Tracy] plants reduced from 0.3 to 0.7 μmol nitrate h−l g−l f. wt. Leaf activity was 4.7–7.6 μmol nitrate h−l g−l f. wt. Outer stem was two to four times more active at reducing nitrate than was inner stem. Plant nitrate nutrition had a strong effect upon the ratio of activity present in stem and leaf. More nitrate increased the proportion present in leaves.
