ABSTRAK Kebutuhan kayu merbau saat ini semakin meningkat, sedangkan keberadaanya di alam semakin berkurang. Oleh karena itu upaya dalam pelestarian merbau darat perlu dilakukan. Ukuran benih berkorelasi dengan vigor benih, dimana benih yang relatif berat cenderung mempunyai vigor yang lebih baik. Penelitian ini bertujuan untuk mengetahui pengaruh ukuran berat benih terhadap perkecam-bahan dan untuk mengetahui ukuran berat benih yang memiliki respon terbaik terhadap persentase kecambah, rata-rata hari berkecambah, nilai kecambah, dan daya kecambah pada benih pohon merbau darat. Penelitian ini dilakukan di rumah kaca Fakultas Pertanian Universitas Lampung pada bulan November 2013 sampai Januari 2014. Penelitian ini disusun dalam Rancangan Acak Lengkap (RAL), dengan 3 perlakuan dan 4 ulangan. Benih diklasifikasikan berdasarkan berat benih yaitu benih berbobot berat, berbobot sedang, dan berbobot ringan. Setiap unit percobaaan menggunakan100 butir benih merbau darat. Variabel yang diamati terdiri dari persentase kecambah, rata-rata hari berkecambah, nilai kecam-bah, dan daya kecambah. Metode analisis data yang digunakan meliputi homogenitas ragam, sidik ragam, dan uji beda nyata terkecil (BNT) pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa ukuran berat benih berpengaruh positif terhadap keberhasilan perkecambahan. Benih berbobot berat ( >3,49 gram) memberikan respon perkecambahan yang lebih baik untuk persentase kecambah 80,250% dan nilai kecambah 1,595 %/hari dibandingkan dengan benih berbobot sedang (2,36--3,49 gram) dan berbobot ringan (< 2,36 gram). Kata kunci : merbau darat, perkecambahan, ukuran benih. ABSTRACT The demand ofmirabowwood is increasingnowdays,where as the existence species in the nature is getting reduced. Therefore, it’s preservation efforts are urgent to be done. Seed size was correlated with it’s vigor, where heavy seeds relatively have a better vigor, compare to the light one. The research was aimed to determine the effect of seed size to percentage of germination, average days to germinate, germination value and germination powerof mirabowseeds. The research was conducted in greenhouse of Agriculture Faculty LampungUniversity onNovember 2013 to January 2014. Theresearch was arranged in CompleteRandom Design (CRD), with 3 treatments and 4 replications. Seed are classified based on the weight of seed is heavy weight, medium weight, and lightweight. Each unit of experiments was used 100 mirabow seeds. The observed variables were consisted of germination percentage, average day to germination, germination value, and germination power. Data analysis methods used were homogeneity of variance, variance analysis, and least significant of difference test at 5% significant level. The results showed that seed sizeof mirabow has a positive effect to the germination. The heavy weight of seed (> 3.49 grams) gave a better response for germination percentage 80.250% and germination value 1.595 %/day compared with the medium weight (2.36--43.49 grams) and lightweight (<2.36 grams). Keywords: germination, mirabow, seed size.
