In order to get a good seed, the source of planting material usually uses 6 - 8 months. Storage of sugarcane bud set aims to maintain the viability of the seeds as long as the bud set is not ready for planting. This research was conducted on the land of the Agriculture Faculty, University of Sumatera Utara, Medan in April - July 2017, using factorial randomized block design with two factors, i.e. age of planting material (6, 7, and 8 months) and storage periods (24, 48, 72 hours). The results showed that 7 months planting material gave the best plant lenght and seeds diameter. Using 7 months planting material with 72 hours storage periods gave best shoot growth percentage.
Guna mendapatkan bibit yang baik, sumber bahan tanam untuk bud set yang digunakan adalah berumur 6 - 8 bulan. Penyimpanan bud set tebu bertujuan untuk mempertahankan viabilitas bibit selama bud set belum siap untuk ditanam. Penelitian ini dilaksanakan di lahan Fakultas Pertanian Universitas Sumatera Utara, Medan pada bulan April – Juli 2017, menggunakan rancangan acak kelompok faktorial dengan dua faktor yaitu berbagai umur bahan tanam (6, 7, dan 8 bulan) dan lama penyimpanan (24, 48, dan 72 jam). Hasil penelitian menunjukkan panjang tanaman dan diameter bibit nyata lebih tinggi pada bahan tanam umur 7 bulan. Persentase tumbuh tunas nyata tertinggi diperoleh pada penggunaan bahan tanam bud set umur 7 bulan dengan lama penyimpanan 72 jam.
