Other claims from this paper (12)
- Intervention effect High aged and thick roots generated numerous white roots after decapitated by root pruning
- Intervention effect The white roots grew more thickly and long than these on intact roots in the control plot
- Intervention effect showing poor curvature and branching
- Intervention effect their both functions steeply lowered during the first crop season
- Intervention effect The white root, however, maintained the activity of apex and respiratory rate that exceeded the similar roots in the control plot over the whole experimental period
- Intervention effect The root pruning caused a decrease in lignified root despite treatment times (Jul. to Nov.)
- Intervention effect induced 10-40% increase in white roots except the treatment in late November
- Intervention effect percentage of the white root to total root weight rose by 10-20% relatively to the control plot
- Intervention effect The most excellent regeneration of roots was observed in 40-60% root pruning plots
- Intervention effect total shoot weight per plant compared poorly with the control plot regardless of treatment times
- Recommendation Root pruning was concluded to induce active root growth and rejuvenate the root system.
- Observation Crop productivity was estimated to rise annually with root system rejuvenation after an initial decrease.
