Respon Viabilitas Dan Vigor Benih Serta Pertumbuhan Vegetatif Generasi M3 Varietas Odeng Terhadap Beberapa Tingkat Cekaman Salinitas

Abstrak. Tujuan penelitian ini adalah untuk mengetahui performansi beberapa galur mutan cabai generasi M3 pada berbagai tingkat cekaman salinitas viabilitas dan vigor benih serta vegetatif tanaman, interaksi antara kedua faktor. Penelitian dilaksanakan di Laboratorium Ilmu Teknologi Benih Rumah Kasa Fakultas Pertanian Universitas Syiah Kuala Banda Aceh bulan Juni sampai Agustus 2021. Percobaan disusun menggunakan rancangan acak lengkap pola faktorial yang terdiri atas 2 faktor 3 ulangan. Faktor pertama lokal dari 5 taraf yaitu sebagai kontrol digunakan varietas Odeng O10 D1-5, O7 D2-39, O9 D3-9, D3-34. konsentrasi NaCl media tanam 4 0 ppm, 5000 7.500 10.000 ppm. Hasil menunjukkan bahwa setiap memiliki respon berbeda terhadap salinitas. Konsentrasi 7,81ds/m (K1), sudah mulai penurunan nilai pertumbuhan tanaman. Viabilitas tertinggi terdapat perlakuan kemudian diikuti oleh D2-39 terendah Varietas odeng, D3-9 daya berkecambah lebih baik dibandingkan dengan lainnya.Response of Viability and Vigor Seed Vegetative Growth Generation Variety to Several Levels Salinity StressAbstract. The purpose this study was determine the performance several generation chili mutant lines at various levels salinity stress on seed viability as well plant vegetativeness, interaction between two factors. This research conducted Laboratory Science Technology Screening House, Faculty Agriculture, University, from June August experiment arranged using a completely randomized design with factorial pattern consisting factors replications. first factor local line which consisted levels, namely variety control D3-34 varieties. second is concentration in growing consists 7,500 10,000 results showed that each had different response salinity. 7.81ds/m started show decrease values seeds vegetative growth plants. highest were found treatment variety, followed by mutant, D1-5 lowest mutant. odeng better germination rates under than other lines.
