Perlakuan Pematahan Dormansi Pada Beberapa Grade Benih Akasia (Acacia Crassicarpa)

---

ABSTRACT
Acacia (Acacia crassicarpa) is a priority species in Indonesia’s industrial forest plantations (HTI), widely used for pulpwood production and land rehabilitation. The seeds of this species exhibit physical dormancy due to an impermeable seed coat, which inhibits germination even under optimal conditions. This study aimed to determine the most effective dormancy-breaking treatment across different seed grades to maintain seed viability and improve germination. A factorial completely randomized design (CRD) was applied, consisting of two factors: seed grade (M, L, XL, XXL) and dormancy-breaking treatment (control, immersion in boiling water for 1 minute, immersion in 98% H2SO4 for 15 minutes, and mechanical scarification). Results showed that grade M seeds had higher germination percentages than XXL seeds. Immersion in 98% H2SO4 for 15 minutes significantly improved standard germination, first count germination, and germination index across all seed grades. The best results were obtained from the combination of grades M, XL, and XXL treated with 98% H2SO4 for 15 minutes, producing superior viability and vigor compared to other treatments. Therefore, concentrated sulfuric acid treatment is an effective method to overcome physical dormancy in A. crassicarpa seeds.
