Turi is one of horticultural plant has many benefits but its existence is increasingly limited. Development of turi should begin with the procurement of high quality seed. Test power germinated is one test used to detect the seeds. Germination of seed resource test procedure is not yet well known as turi methods break dormancy, germination substrates that are effective, as well as the first count and final count so that research needs to be done. The research was carried out in a Laboratory Storage and Seed Quality Testing of IPB in May-September 2017. That test results obtained from the seeds of turi germination for 21 days is the first count on day 6 and final count on day 8. The most maximum germination substrate is merang paper then filter paper. Turi also have dormancy so need to be given preferential treatment so that the dormancy was broken and easy to germinate. Scarification (sandpaper) method is the best method in breaking seed dormancy of turi. ABSTRAKTuri merupakan salah satu tanaman hortikultura yang memiliki banyak manfaat namun keberadaannya semakin terbatas. Pengembangan tanaman turi harus dimulai dengan pengadaan benih yang bermutu tinggi. Uji daya berkecambah adalah salah satu pengujian yang digunakan untuk mendeteksi benih. Prosedur pengujian daya berkecambah benih turi belum banyak diketahui seperti metode pematahan dormansi, substrat perkecambahan yang efektif, serta first count dan final count sehingga perlu dilakukan penelitian. Penelitian ini dilaksanakan di Laboratorium Penyimpanan dan Pengujian Mutu Benih IPB pada bulan Mei-September 2017. Hasil pengujian yang diperoleh dari pengecambahan benih turi selama 21 hari adalah hitungan pertama (first count) nya pada hari ke-6 dan hitungan kedua (final count) pada hari ke-8. Substrat perkecambahan yang paling optimum untuk mengecambahkan benih turi adalah kertas merang kemudian kertas saring. Turi juga memiliki dormansi sehingga perlu diberikan perlakuan supaya dormansinya patah dan mudah untuk berkecambah. Metode skarifikasi (pengamplasan) adalah metode terbaik dalam mematahkan dormansi benih turi.Kata kunci: amplas, hitungan kedua, hitungan pertama, kertas merang Bul.
