Other claims from this paper (6)
- Observation Rice nursling root systems contain a seminal root and crown roots from the coleoptilar node.
- Intervention effect Cutting roots 1.5 cm from the base gave growth similar to the control.
- Intervention effect Cutting roots to 0.5 cm significantly reduced growth.
- Intervention effect Cutting the bases of a seminal and longest crown root severely reduced growth.
- Association Transplanted seedling growth decreased with remaining total root length.
- Mechanism Authors conjecture crown roots promote post-transplant rooting and development through water and nutrient uptake.
