Effect of spacing on growth, carbon sequestration, and wood quality of 8-year-old clonal teak plantation for sustainable forest teak management in Java Monsoon Forest, Indonesia

Abstract. Rahmawati RB, Widiyatno, Hardiwinoto S, Budiadi, Nugroho WD, Wibowo A, Rodiana D. 2022. Effect of spacing on growth, carbon sequestration, and wood quality 8-year-old clonal teak plantation for sustainable forest management in Java Monsoon Forest. Biodiversitas 23: 4180-4188. Lowland monsoon dominated by was one the tropical types that can contribute to producing production, storage, reduction emissions, other ecosystem services. Increasing productivity could be obtained through breeding get superior clones with high diameter growth. Thus, is an important consideration optimizing properties teak. However, study conducted separately. This research used a selected clone aged 8 years RCBD design 4 blocks as replications. There were four different treatments, namely 10 m x 2 m, 6 3 m. The results showed significant effect DBH, tree height, bole volume years. On hand, didn’t significantly affect physical mechanical wood. test had values bending strength compressive parallel. highest percentage heartwood at narrow did not differ wide spacing. indicated beneficial terms but
