- Intervention effect Exogenous 2,4-D added at sowing considerably depressed soybean shoot and root development.
- Intervention effect The increase in nodules per cm lateral root in plants treated 3 d after sowing was about twice that of the treatment at sowing.
- Intervention effect Total nodules at harvest relative to the control increased in plants treated 3 d after sowing.
- Intervention effect Total nodules at harvest relative to the control decreased in plants treated with 2,4-D at sowing.
- Intervention effect Plants treated with 2,4-D showed nitrogenase (acetylene reduction) activity per plant similar to the comparison plants.
- Observation Specific nodule activity in soybean was highly variable.
- Association Nodule activity is independent of nodule number and nodule weight in soybean.
- Intervention effect Most cortical cell divisions in soybean, notably in 2,4-D-treated plants, were arrested at the nodule developmental stage before nodule emergence.
