Intervention effect AM colonization increased branching intensity in all root orders.
Intervention effect First order lateral branch density rose from under 100 to over 300 branches per meter.
Intervention effect First order laterals represented 36% of AM infected versus 55% of control root systems.
Intervention effect Second order laterals represented 50% of AM colonized versus 25% of control root systems.
Intervention effect G. intraradices increased root diameter.
Observation Anatomical studies found no overall root tip form change.
Observation Anatomical studies found changes in root cap diameter, cell number and cell size.
