抄録

The tree height growth of individual trees of Engkabang jantong (Shorea macrephylla) was monitored in a plantation forest, which was established at the Semengoh forest reserve, Kuching district. Sarawak, Malaysia in 1973, The assessment of tree height growth was repeated fifteen times during 21 observation years. Mean height was 19.3 m at the stand age of 21 years old, The growth trajectories with respect to time after planting were approximated by the simple logistic equation, of which three coefficients were determined by the non-linear least squares method. The coefficients were the intrinsic growth rate r, carrying capacity K, and coefficient k₀ determined by initial conditions, The mean estimated r of 0.2983/year represented very rapid initial growth of E, jantong compared with Cryptomeria japonica commonly used in Japanese plantation forestry. The repulsive relationship was observed between r and K and framed the r-K continuum, which could visualize a position of an individual along it and suggested a resource limit in partitioning mass and energy into two contrasting biological functions, r and K. Furthermore, unusually large r values for dead trees might be an adaptation against damages caused by planting trees and animal herbivores. All these results were strongly linked with promising properties of E, jantong as a species potentially available in the plantation forestry in the tropics.
