Variations in growth, crown architecture, and leaf functional traits in a progeny trial of Tectona grandis L.f. in Indonesia

berita penelitian dan publikasi Wednesday, 24 September 2025

Abstract
Teak (Tectona grandis) is a valuable tropical timber species, but knowledge about its environmental adaptability for tree breeding is limited. Progeny trial is crucial for improving breeding materials as progeny performance and resilience to environmental stresses can be assessed for future breeding effort. In this study, we examined the variations in growth, crown architecture and leaf traits in a progeny trial in Indonesia. We retained the best components read more

Characterization of Wood Extractives and Antioxidant Activity in Acacia Hybrid (Acacia mangium × Acacia auriculiformis) Grown in Wonogiri, Indonesia

Abstract
This study aimed to evaluate extractive composition and antioxidant activity of Acacia hybrid (Acacia mangium × Acacia auriculiformis) variety, namely Purwo Sri Ah015D wood, as a first step in future development to improve resistance to diseases. Wood powder from axial (bottom, middle, top) and radial (near pith and near bark) positions were successively extracted by n-hexane, methanol, and hot water solvents. The dried extracts (except n-hexane) were used read more

Genetic diversity and population structure of Shorea macrophylla using genome-wide single-nucleotide polymorphisms and microsatellite markers in Indonesia for conservation

berita penelitian dan publikasi Tuesday, 9 September 2025

Abstract
In the tropical forests of Southeast Asia, the dipterocarp species stands out as the most significant tree group in terms of ecosystem stability and forestry management. Shorea macrophylla, found on Borneo Island, is particularly noteworthy for its rapid growth, high oil content nut production, and versatile timber characteristics, making it a prime candidate for plantation material in rehabilitating degraded forests. We collected population samples of S. macrophylla read more
