PENGARUH KONSENTRASI FILTRAT BAWANG MERAH (Allium cepa L.) DAN LAMA PERENDAMAN TERHADAP VIABILITAS DAN VIGOR BENIH KUBIS (Brassica oleracea L.)

THE EFFECT OF ONION (Allium cepa L.) FILTRATIC CONCENTRATION AND SOAKING LENGTH ON CABBAGE (Brassica oleracea L.) SEED VIABILITY AND VIGOR

Penyimpanan benih terlalu lama berpengaruh pada rendahnya kualitas produksi kubis. Alternatif cara yang dapat dilakukan untuk mendorong pertumbuhan kubis, yaitu pemberian filtrat bawang merah yang mengandung hormon pertumbuhan auksin dan giberelin. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi konsentrasi dan lama waktu perendaman filtrat bawang merah (Allium cepa L.) terhadap viabilitas dan vigor benih kubis (Brassica oleracea L.). Desain penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan kombinasi konsentrasi filtrat bawang merah (0%, 50%, 75%, dan 100%) serta lama perendaman (0 jam, 3 jam, 6 jam, dan 9 jam) sebanyak 3 kali pengulangan, sehingga diperoleh 48 unit penelitian. Data viabilitas dan vigor benih yang diperoleh yaitu daya kecambah, indeks vigor, kecepatan tumbuh, serta keserempakan tumbuh dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan adanya pengaruh pada perlakuan konsentrasi filtrat bawang merah 0% dan 75% serta lama perendaman benih selama 0 jam dan 3 jam terhadap viabilitas dan vigor kubis yang telah kadaluarsa selama delapan bulan.

Storing seeds for too long has an impact on the low quality of cabbage production. An alternative method that can be used to encourage cabbage growth is giving onion filtrate, which contains the growth hormones auxin and gibberellin. This research aims to determine the effect of the combination of concentration and soaking time of onion filtrate (Allium cepa L.) on the viability and vigor of cabbage seeds (Brassica oleracea L.). This research design used a Randomized Block Design (RAK) with a combination of onion filtrate concentration (0%, 50%, 75%, and 100%) and soaking time (0 hour, 3 hours, 6 hours, and 9 hours) was repeated 3 times, so that 48 research units were obtained. The seed viability and vigor data obtained, namely germination power, vigor index, growth speed, and growth synchrony, were analyzed descriptively and quantitatively. The results of the research showed that there was an effect on the treatment of onion filtrate concentrations of 0% and 75% and the soaking time of the seeds for 0 hours and 3 hours on the viability and vigor of cabbage that had expired for eight months.
