Other claims from this paper (17)
- Observation Soybean absorbed little Mo up to the flower-bud-appearing stage.
- Mechanism Mo accumulation in nodules may depend strongly on seed Mo early in growth.
- Mechanism Seed Mo may have an important role in early soybean growth.
- Observation Soybean began absorbing soil Mo after the middle of June.
- Observation Mo concentrations increased in all soybean parts after the middle of June, especially nodules.
- Observation During pod filling, Mo concentration in roots and pod shells fell rapidly.
- Observation During pod filling, seed Mo concentration increased.
- Observation Mo concentrations in nodules, stems and leaves declined only slightly.
- Mechanism Translocation of Mo from nodules, stems and leaves to seeds was inferred to be negligible.
- Observation Soybean seed Mo concentrations from Hokkaido were very low.
- Association Soybean seed Mo concentrations rose with decreasing latitude up to central Japan.
- Association Seed Mo concentration had no significant geographic trend in southwest Japan.
- Association Mn, Fe, Cu and Zn did not show the geographic trend observed for Mo.
- Association Earlier maturing soybean varieties had lower seed Mo concentrations.
- Association Late maturing soybean varieties had high seed Mo concentrations.
- Association Seed concentrations of Mn, Fe, Cu and Zn showed no such maturity relationship.
- Mechanism Soybean seed Mo concentration may depend more on maturity habit than soil conditions except under Mo deficiency.
