Other claims from this paper (10)
- Intervention effect Pod removal significantly decreased soybean dinitrogen-fixing activity.
- Intervention effect Defoliation significantly decreased soybean dinitrogen-fixing activity.
- Intervention effect Pod removal increased sugars and starch concentrations in soybean nodules.
- Intervention effect Complete defoliation decreased sugars and starch concentrations in soybean nodules.
- Intervention effect Partial defoliation did not change sugars and starch concentrations in soybean nodules.
- Intervention effect Complete defoliation especially increased ureide concentration in soybean xylem exudate and nodules.
- Intervention effect Pod removal decreased the export rate of 14C from soybean leaves.
- Intervention effect Pod removal had no effect on the percentage distribution of 14C in soybean nodules.
- Intervention effect Depodded soybean plants had a lower xylem sap ureide-14C exudation rate in the first hour, then a higher rate than controls.
- Mechanism The authors suggest soybean dinitrogen fixation under ordinary field conditions is controlled by fixed nitrogen export from nodules rather than photosynthate supply.
