Abstract

The International Union for Conservation of Nature (IUCN) Red List has categorized the Southeast Asian native species Aquilaria malaccensis as severely endangered due to the great demand for its agarwood. The purpose of the study was to assess the growth performance of Lapnisan (Aquilaria malaccensis) seedlings in varying sand concentrations. The study employed a Complete Randomized Design (CRD) method with four treatments, this include Treatment 1 (T1)-pure top soil, Treatment 2 (T2)- topsoil and sand soil (1:1 ratio), Treatment 3 (T3)- topsoil and sand soil (3:1 ratio), and Treatment 4 (T4)- topsoil and sand soil (1:3 ratio) with three replications per treatment. The effects of these treatments were evaluated based on percent survival, number of leaves, branches and stem diameter. Based on the study, there were significant differences among the treatments. Lapnisan seedlings in T2 produced more branches (3.78) and a greater number of leaves (39.56) compared to the other treatments. In contrast, Lapnisan in T3 developed a thicker stem diameter (6.89). Notably, Lapnisan seedlings in Treatment 4 achieved a 100% survival rate out of the four treatments. These results suggested that a high sand concentration is the most suitable for cultivating Lapnisan seedlings, as it significantly increased their chance of survival.
