Abstract

This study aims to evaluate the second-year growth performance of kenari trees (Canarium amboinensis) from two different provenances Nikulukan Village (Seram Island) and Kilang Village (Ambon Island) planted at the Seed Orchard in Hatusua Village, Kairatu Subdistrict, West Seram Regency. A census method was applied to assess 800 kenari trees from both provenances. Parameters observed included plant height, diameter, survival rate, and environmental factors such as soil pH, air and soil humidity, rainfall, light intensity, and temperature. The results showed that the provenance from Nikulukan had a higher survival rate (95.25%) compared to Kilang (91.25%). A two-sample t-test revealed significant differences in height and diameter between the two provenances, with Nikulukan showing better growth performance. As environmental conditions were similar across the planting site, the differences in growth are presumed to be caused by the genetic adaptation of each provenance to the site.

Abstract

This study aims to determine the potential of dusung and the distribution patterns of dusung plants in Hila Village, Leihitu District, Central Maluku Regency. The method used in this research is a purposive sampling survey method. Vegetation found in the research area consisted of 7 plots with a total area of 98.00 m² or 0.98 ha. There are species that dominate at each level. At the tree level, the dominant species is gandaria with species: Bouea macrophylla and family: Anacardiaceae. At the pole level, the dominant species is clove with species: Syzygium aromaticum and family: Myrtaceae. At the sapling level, the dominant species is nutmeg with species: Myristica fragrans and family: Myristicaceae. Meanwhile, at the seedling level, the dominant species is clove with species: Syzygium aromaticum and family: Myrtaceae. The distribution pattern index shows the magnitude of the distribution pattern index value from each level, namely seedling level of 0.07, pole level of 0.13, sapling level of 0.14, and tree level of 0.11. The distribution pattern of plants at the seedling, sapling, pole, and tree levels falls into the category of clustered distribution pattern.
