Abstract

This study aims to determine the effect of several immersion methods on dormancy breaking and methods that can accelerate dormancy breaking of Ciherang rice seeds. The experimental design used was a one-factor completely randomized design, namely the immersion method with 5 levels of treatments: the non-immersion method (P0), the immersion method using water at 30°C for 24 hours (P1), the immersion method using hot water with an initial temperature of 60°C for 24 hours. 24 hours (P2), the immersion method used a GA3 solution with a concentration of 0.5 ppm for 24 hours (P3), and the immersion method used a 3% KNO3 solution for 48 hours (P4) with five replications. The research was conducted at the Laboratory of Plant Breeding and Seed Technology, Faculty of Agriculture, Udayana University from September 2020 to November 2020. The results showed that the immersion method had a very significant effect on the germination variable (%), maximum growth potential (%), dormancy intensity (%), and speed of germination (%/etmal), and significantly affect the growth of seed fungus (%). P3 treatment was able to break the dormancy of rice seeds for 5 weeks of observation with the highest germination value (95.16%) and obtained the smallest dormancy intensity value (4.56%) better than P0 treatment without soaking (control) obtained a germination value of (7.76%) and the value of dormancy intensity (89.52%). The highest germination rate was obtained in treatments P3 and P4, which were (6.08%/etmal) and (3.35%/etmal, respectively).

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh beberapa metode perendaman terhadap pematahan dormansi serta metode yang mampu mempercepat pematahan dormansi benih padi varietas Ciherang. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap satu faktor yaitu metode perendaman dengan 5 taraf perlakuan: metode tanpa perendaman (P0), metode perendaman menggunakan air bersuhu 30 °C selama 24 jam (P1), metode perendaman menggunakan air panas dengan suhu awal 60°C selama 24 jam (P2), metode perendaman menggunakan larutan GA3 dengan konsentrasi 0,5 ppm selama 24 jam (P3), dan metode perendaman menggunakan larutan KNO3 dengan konsentrasi 3% selama 48 jam (P4) dengan lima kali ulangan. Penelitian dilaksanakan di Laboratorium Pemuliaan Tanaman dan Teknologi Benih Fakultas Pertanian Universitas Udayana pada bulan September 2020 sampai November 2020. Hasil penelitian menunjukkan metode perendaman berpengaruh sangat nyata terhadap variabel daya kecambah (%), potensi tumbuh maksimum (%), intensitas dormansi (%), dan kecepatan berkecambah (%/etmal), serta berpengaruh nyata terhadap pertumbuhan jamur benih (%). Perlakuan P3 mampu mematahkan dormansi benih padi selama 5 minggu pengamatan dengan nilai daya kecambah tertinggi (95,16%) dan memperoleh nilai intensitas dormansi terkecil (4,56%) lebih baik dibandingkan dengan perlakuan P0 tanpa perendaman (kontrol) memperoleh nilai daya kecambah sebesar (7,76%) dan nilai intensitas dormansi sebesar (89,52%). Kecepatan berkecambah tertinggi diperoleh pada perlakuan P3 dan P4 yaitu masing-masing (6,08%/etmal) dan (3,35%/etmal).
