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.
