KEMAMPUAN TUMBUH BIJI ALFALFA HASIL MUTASI

ABSTRACT Alfalfa (Medicago sativa) was one of the temperate legumes, palatable and nutritious that content high in protein, vitamin and mineral. The purpose of this study examines the effect of Ethyl Methyl Sulfonate (EMS) on the ability to grow of subtropical mutations alfalfa seed . The design was the complete randomized block design 4 treatments (EMS concentrations of 0; 0.11; 0.22 and 0.33%) with 5 replicates. The variables observed were germination, vigor index and the coefficient of vigor. Results of analysis of variance showed that the dosage EMS significant effect on germination and vigour index but did not significantly affect the coefficient of vigour The highest yield germination and vigor index at 0.11% EMS treatment respectively by 48% and 5:57. Alfalfa can be flowering and seeding in the tropics. EMS 0:11% increase germination and vigor index of seeds produced. Keywords: the ability to grow seeds, alfalfa subtropical, EMS ABSTRAK Tanaman alfalfa (Medicago sativa ) merupakan leguminosa yang biasa tumbuh di daerah temperate, bergizi, kaya protein, dan mineral serta disukai ternak. Tujuan penelitian ini mengkaji pengaruh Ethyl Methyl Sulfonate (EMS) terhadap kemampuan tumbuh biji hasil mutasi alfalfa sub tropis. Rancangan yang digunakan Rancangan Acak lengkap 4 perlakuan (konsentrasi EMS 0; 0,11; 0,22 dan 0,33%) dengan 5 ulangan. Variabel yang diamati daya kecambah, vigor indeks dan koefisien vigor. Hasil analisis ragam menunjukkan bahwa pemakaian dosis EMS berpengaruh sangat nyata terhadap daya kecambah dan vigor indeks tetapi tidak berpengaruh nyata terhadap koefisien vigor. Hasil tertinggi daya kecambah dan vigor indeks pada perlakuan EMS 0,11 % masing-masing sebesar 48% dan 5.57. Alfalfa dapat berbunga dan berbiji didaerah tropis. EMS 0,11% meningkatkan daya kecambah dan vigor indeks biji yang dihasilkan. Kata kunci: kemampuan tumbuh biji, alfalfa sub tropis, EM
