Other claims from this paper (12)
- Observation Cucumber accumulated more than pea.
- Observation Only 2% of cucumber reductase activity was in roots.
- Observation Nearly 92% of cucumber reductase activity was in blades.
- Observation Pea reductase activity was more evenly distributed.
- Observation Pea blades contained 67% of reductase activity.
- Observation Pea roots contained 18% of reductase activity.
- Observation Cucumber root bleeding sap contained 80% nitrate nitrogen.
- Observation Pea root sap contained 30% nitrate nitrogen.
- Observation The remaining 70% of pea root sap nitrogen consisted of amino acids and amides.
- Observation Asparagine or aspartic acid was the major reduced nitrogen carrier in pea.
- Observation Glutamine was the major reduced nitrogen carrier in cucumber.
- Mechanism Differences in nitrogen transport and assimilation appear related to plant composition and nitrogen use efficiency.
