Other claims from this paper (11)
- Intervention effect Soil fertility treatments significantly influenced jack bean growth, seed yield, and nodulation.
- Intervention effect Phosphorus limited jack bean top growth: potassium or calcium without phosphorus did not increase it.
- Association Mature jack bean seed yield correlated with top growth at r = 0.67.
- Association Mature jack bean seed yield correlated with nodulation at r = 0.58.
- Intervention effect Phosphorus increased jack bean nodulation only when combined with potassium.
- Association A regression using top growth, nodule mass, and seed mass explained nitrogenase activity with R2 = 0.81.
- Association A regression using nodule cytosol composition explained nitrogenase activity with R2 = 0.78.
- Observation Jack bean seed canavanine increased from 6.08 mg to 32.8 mg g"1 seed between 104 and 149 days.
- Observation Jack bean seed Concanavalin A increased from 5.05 to 44.0 mg g‐1 seed.
- Observation Jack bean seed urease increased from 97.0 to 215.8 IU g‐1 seed.
- Observation Jack bean nodule histology reflected changes in cytosol lipids and ureides and vacuolation of active cells.
