Title

Other claims from this paper (9)
- Association Nitrate content of the wheat tissue was a major factor controlling the level of nitrate reductase activity.
- Association Nitrate reductase activity was related, though not numerically, to leaf protein content.
- Intervention effect Supplemental nitrogen induced nitrate reductase on a field scale compared with no supplemental nitrogen.
- Association Increased enzyme activity from supplemental nitrogen treatments was associated with increases in grain protein (% or total).
- Association The spring seasonal total of nitrate reductase activity correlated significantly with grain protein for both varieties.
- Mechanism The observation suggests that Monon is more efficient than Ponca in transporting reduced nitrogen from the vegetation to the grain.
- Observation Among 32 winter wheat varieties in a low-nitrogen nursery, average nitrate reductase activity showed little variation among genotypes.
- Association Average enzyme activity across the 32 varieties showed no correlation with grain or grain protein production.
- Method / resource Selecting the 16 varieties with highest nitrate reductase activity on November 12 would have included 9 of the 13 varieties that ultimately produced significantly higher grain protein.
