Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis hidropriming dan lama penyimpanan benih terhadap viabilitas dan kekuatan benih kopi lokal Solok Selatan. Rancangan penelitian ini adalah rancangan acak kelompok (RAK) faktorial dengan dua perlakuan yaitu jenis hidropriming dan lama penyimpanan. Faktor pertama terdiri dari empat tingkat. Yaitu, P1 = Hydropriming dengan air biasa, P2 = Hydropriming dengan 100 ppm GA3, P3 = hydropriming dengan air kelapa, dan P4 = hydropriming dengan ekstrak bawang merah. Elemen kedua terdiri dari tiga tingkat. L1 = periode penyimpanan 1 minggu. L2 = periode penyimpanan 2 minggu. L3 = penyimpanan 3 minggu. Hasil evaluasi penelitian menjelaskan bahwa jenis hidropriming dan lama penyimpanan memiliki pengaruh interaksi namun tidak berpengaruh nyata terhadap potensi tumbuh maksimum, indeks vigor, dan laju perkecambahan. Jenis hidropriming yang memberikan hasil  baik dalam hal potensi pertumbuhan maksimum, indeks vigor dan laju perkecambahan adalah penggunaan air biasa dan ekstrak bawang. Kedua jenis hydropriming ini dapat membantu meningkatkan kadar air dan daya serap benih sehingga meningkatkan kelangsungan hidup dan vigor benih. Selain itu, umur simpan benih kopi dalam jangka panjang adalah satu minggu penyimpanan. Hal ini menunjukkan respon yang baik terhadap viabilitas.

Abstract

Plant germplasm plays an important role in maintaining genetic diversity and sustainability of plant cultivation, including coffee. Seed viability testing is a crucial step in ensuring seed quality before being used for planting. The role of coffee germplasm development is carried out to store high-potential coffee varieties, including those with good adaptation and resistance properties. In addition to maintaining coffee germplasm, seed viability testing is also important to ensure effective genetic conservation and maintenance of valuable coffee genetic resources. The purpose of this study was to determine the seed viability of several coffee cultivars with several treatments and to determine the viability and vigor of seeds after a long storage period. The experimental design used was a factorial Randomized Block Design (RAK), with two factors. The first factor is the coffee cultivar (K) consisting of 4 levels, namely: K1 = Tuo coffee, K2 = Ciari coffee, K3 = Manak coffee and K4 = Bengkulu coffee. The second factor is the dormancy breaking method (P) which consists of four levels, namely: (1) breaking the dormancy of several coffee seed varieties by giving growth stimulating hormones, namely GA3 300 ppm f (D1), (2) breaking dormancy chemically with H2SO4 with a concentration of 20% (D2), (3) soaking coffee seeds in warm water at a temperature of 60˚C (D3), (4) soaking seeds in plain water (D0). from this study is that by providing the dormancy breaking method with the soaking method with GA3 at a concentration of 300 ppm in increasing the maximum growth potential of coffee seeds, however, giving different types of coffee treatments and combinations of different types of coffee and dormancy breaking have not shown significantly different results.
