The effect of nursery media and growth regulatory substance on the success of eucalyptus cuttings at PT Solusi Bangun Indonesia

\nEucalyptus (Melaleuca leucadendra) is a fast-growing species with a good adaptation level and is widely grown, especially on marginal land. Eucalyptus seedling production is done through shoot cuttings. This study aims to determine the effect of nursery media and plant growth regulators (PGR) on the success of eucalyptus cuttings. The research was conducted for seven weeks using various nursery media and PGR. The research design used a completely randomized design and one-way ANOVA followed by Duncan’s test. Results showed that the percentage of live shoot cuttings was 77%. Shoot cuttings that sprouted showed a total rate of 65%, with a total percentage of roots reaching 34%. The ability of shoot cuttings to sprout and roots simultaneously showed a total percentage of 32%. The treatment of nursery media only really affects the percentage of life and sprouting, while the ability to take root and sprout does not have real effects. Applying PGR significantly influences the rate of life, the ability to sprout and roots, and the ability to root sprouts on the cuttings. The interaction of those factors influences the percentage of life and sprout cuttings.\n
