Abstract: Swietenia macrophylla atau mahoni berdaun lebar adalah jenis eksotik dari Amerika Tengah dan Selatan. Pohon ini memiliki berbagai manfaat dan kegunaan. Penyimpanan benih masih menjadi permasalahan yang utama, karena dapat menurunkan viabilitas benih. Daya simpan benih dipengaruhi oleh kondisi benih dan kondisi lingkungan. Oleh karena itu, penelitian ini bertujuan menguji pengaruh suhu dengan masa simpan terhadap viabilitas benih mahoni serta menghitung Indeks Mutu Bibit (IMB). Percobaan dilakukan menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor. Faktor pertama terdiri atas empat taraf perlakuan suhu yaitu suhu ruang (24 °C), 4 °C, 0 °C, dan -20 °C. Faktor kedua yaitu perlakuan masa penyimpanan yang terdiri atas 4 taraf yaitu 1 sampai 4 minggu, dengan interval 1 minggu. Hasil penelitian menunjukkan bahwa interaksi suhu dan masa simpan memengaruhi jumlah daun, jumlah akar primer dan sekunder, nisbah tajuk akar, dan bobot basah total bibit mahoni. Benih mahoni yang disimpan pada suhu kamar selama 1 minggu menghasilkan viabilitas benih terbesar, dengan benih mahoni yang disimpan pada suhu ruang selama 1 minggu menghasilkan viabilitas benih tertinggi sebesar 80%, IMB dengan nilai 0,03 ̶ 0,04.
Swietenia macrophylla or big-leaf mahogany is an exotic species from Central and South America. This tree has various benefits, so it’s used as an industrial plantation forest and afforestation in Indonesia. However, seed storage of mahogany is a major problem in cultivation, because it can reduce seed viability. The storability of seeds is influenced by seed and environmental conditions. Therefore, this study aimed to examine the effect of temperatureand storage time on the viability of S. macrophylla seeds and to calculate the Seedling Quality Index (SQI). The experiment was carried out using a factorial Randomized Block Design (RBD) with 2 factors. The first factor has consisted of four levels of temperature treatment, namely room temperature (24 °C), 4 °C, 0 °C, and -20 °C. The second factor was the storage period treatment which consisted of 4 levels, namely 1 up to 4 weeks, with 1-week intervals. The results showed that the interaction between temperature and storage time affected the number of leaves, primary and secondary roots, root/shoot ratio, and total wet weight of S. macrophylla seedlings. Mahogany seeds that were stored at room temperature for 1 weekresulted in the highest seed viability, with SQI of 0,.03 - 0,.04.
