Abstract

PENGARUH LAMA PERENDAMAN DAN KONSENTRASI KALIUM NITRAT TERHADAP PEMATAHAN DORMANSI BENIH JATI Oleh : Rizki Evindo Velawi 13011044 INTISARI Perbanyakan jati secara generatif menghadapi kendala karena kulit biji yang keras sehingga memerlukan perlakuan khusus supaya biji dapat berkecambah. Penelitian ini bertujuan untuk mengetahui lama perendaman dan konsentrasi kalium nitrat yang terbaik untuk mempercepat dan meningkatkan perkecambahan benih jati serta pengaruhnya terhadap pertumbuhan bibit jati. Penelitian dilakukan di laboratorium Agronomi dan Kebun Percobaan Gunung Bulu Universitas Mercu Buana Yogyakarta pada bulan Mei sampai Juli 2017. Penelitian ini merupakan percobaan faktorial 2 x 4 yang disusun dalam Rancangan Acak Lengkap (RAL) dengan empat ulangan. Faktor pertama adalah lama perendaman yang terdiri atas dua aras yaitu 12 dan 24 jam, dan faktor kedua adalah konsentrasi kalium nitrat terdiri atas empat aras yaitu 0, 1, 2, dan 3%. Hasil penelitian menunjukkan ada interaksi antara perlakuan lama perendaman dan konsentrasi kalium nitrat pada perkecambahan benih dan pertumbuhan bibit jati. Kombinasi perlakuan lama perendaman 24 jam dan konsentrasi kalium nitrat 3% menunjukkan perlakuan yang paling baik untuk mempercepat dan meningkatkan perkecambahan benih jati serta pertumbuhan bibit jati. Kata kunci : jati, dormansi benih, kalium nitrat. xiv THE EFFECT OF SOAKING DURATION AND POTASSIUM NITRATE CONCENTRATION ON DORMANCY BREAKING OF TEAK SEED By : Rizki Evindo Velawi 13011044 ABSTRACT The propagation of teak generatively facing constraint due to hard seed coat so it requires special treatment so that the seeds can germinate. This study aims to determine the best soaking duration and potassium nitrate concentration to accelerate and increase the seed germination of teak and its effect on the seedling growth of teak. The research was conducted in Agronomy Laboratory and Experimental Station II (Gunung Bulu) of Mercu Buana Yogyakarta University from May to July 2017. This research is a 2 x 4 factorial experiment arranged in Completely Randomized Design (CRD) with four replications. The first treatment factor is soaking duration consists of two levels, i.e.: 12 and 24 hours. The second treatment factor is potassium nitrate concentration consists of four levels, i.e.: 0, 1, 2, and 3%. The results showed there was an interaction between soaking duration and potassium nitrate concentration treatment on seed germination and seedling growth of teak. Combination of 24 hours soaking duration and 3% potassium nitrate concentration treatment showed the best treatment to accelerate and increase seed germination and seedling growth of teak. Keywords: teak, seed dormancy, potassium nitrate.
