Adaptive strategies in architecture and allocation for the asymmetric growth of camphor tree (Cinnamomum camphora L.).

The stability-related asymmetry in roots, trunk, and crown is always found as a typical effect of biomechanical design under heterogeneous stimulus environment. However, it appears to be a conflict between the biomechanical principle and the source-sink distance of nutrient allocation strategies when the orientational asymmetry occurs. Adaptive growth strategies associated with biomass and nutrient allocation remain to be explored.

Interactive responses of root and shoot of camphor tree ( L.) to asymmetric disturbance treatments.

Plant root and shoot growth are closely interrelated, though the connotation of root-shoot balance should not be limited to their connectivity in biomass and physiological indicators. Their directional distribution of mass in architecture and the resulting root-shoot interactions are the keys to understanding the dynamic balance of the below- and above-ground organs related to tree anchorage. This study focuses on the 4-year-old camphor tree ( L.
