Other claims from this paper (15)
- Intervention effect Root cap removal after hypoxia was more effective than root tip removal in suppressing the inhibitory effects of hypoxia on soybean.
- Intervention effect Shoot dry weight with root cap removal after hypoxia was 51.2% of the control.
- Intervention effect Root dry weight with root cap removal after hypoxia was 43.2% of the control.
- Intervention effect Root dry weight after hypoxia without root cap removal was 62.8% of the control.
- Mechanism The root cap may be the candidate tissue for a stress memory mechanism in soybean.
- Intervention effect Anaerobic stress at the R1 stage significantly decreased branch number, pod weight in the main stem and root length compared with the control.
- Intervention effect Anaerobic stress at the R1 stage significantly decreased root surface area compared with the control.
- Intervention effect Root pruning increased branch number 1.13 times relative to plants treated with anaerobic stress.
- Intervention effect Root pruning increased pod weight 1.14 times relative to plants treated with anaerobic stress.
- Intervention effect Root pruning increased root length 1.12 times relative to plants treated with anaerobic stress.
- Intervention effect Root pruning increased root surface area 1.13 times relative to plants treated with anaerobic stress.
- Observation Plasmolysis was observed in the root meristem, columella and cortical cells of soybean roots under anaerobic conditions.
- Observation Damage was not observed in newly emerged roots after root pruning in plants treated with anaerobic stress.
- Mechanism The effectiveness of root pruning may be due to regeneration and elongation of healthy lateral roots during recovery.
- Intervention effect Root pruning just after anaerobic stress at the R1 stage was ineffective, so growth reduction at reproductive stages may be difficult to suppress with root pruning alone.
