Sandalwood (Santalum album Linn.) is an endemic plant of East Nusa Tenggara that has high economic value, particularly from its heartwood and essential oil. However, generative propagation through seeds still faces challenges due to dormancy, which results in low germination rates. This study aimed to investigate the impact of boron concentration and natural plant growth regulators (PGRs) derived from coconut water on the germination of sandalwood seeds. The experiment was arranged in a factorial Completely Randomised Design (CRD) with two factors: boron concentrations (0,3 gram, 0,4 gram, dan 0,5 gram H3BO3) and coconut water PGR concentrations (0%, 25%, 50%, and 75%), with three replications. The observed parameters included germination percentage, germination value, seedling fresh weight, and seedling dry weight.The results showed that the interaction between boron and coconut water PGR had a highly significant effect on all observed parameters. The best treatment was obtained from the combination of P2B2 (50% coconut water PGR and 0,4 gram boron), which produced the highest germination percentage, germination speed index, germination value, as well as seedling fresh and dry weight. These findings demonstrate that the application of boron at the appropriate dose, combined with natural PGRs from coconut water, is effective in breaking seed dormancy and improving the germination quality of sandalwood seeds.
