Abstract

Konjac (Amorphophallus muelleri) is a plant that can be a source of carbohydrates and has high economic value. To accelerate the fulfillment of porang seeds in order to support maximum economic potential, it is necessary to develop alternative propagation techniques,which is in vitro culture. This study aimed to determine the effect of adding the glycine amino acid to MS medium on the growth of konjac callus and to determine the best concentration for callus growth in konjac plant tissue culture. This research was using frog bulb (bulbil) for the explant. In this study used a completely randomized design (CRD) with glycine amino acid concentrations from 0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, 4 mg/L, dan 5 mg/L with 3 replications. Data were analyzed using SPSS software with one way ANAVA and further test using DMRT 5%.The results showed that the addition of the glycine amino acid to MS medium affected the callus growth of konjac plant tissue culture based on the analysis of variance (ANAVA) test. The best concentration used based on the Duncan Multiple Range Test (DMRT) 5%, was 4 mg/L with the average callus appearance time of 3.06 wac and the average bending time of 2.1 wac.

Abstract

Abstrak. Porang merupakan sumber karbohidrat yang bernilai ekonomi tinggi. Untuk memenuhi permintaan porang sebagai produk diversifikasi pangan maupun produk ekspor, perlu dukungan ketersediaan benih dan budidaya yang memadai. Perbanyakan secara in vitro menjadi alternatif dalam pemenuhan bibit porang yaitu melalui metode kultur kalus dengan menggunakan zat pengatur tumbuh BAP pada media MS. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan BAP terhadap induksi kalus tanaman porang (Amorphophallus muelleri). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan beberapa konsentrasi BAP yang terdiri dari 6 level (0, 1, 2, 3, 4, 5) mg/liter sebanyak 6 ulangan. Data yang diperoleh dianalisis dengan uji one way ANOVA dan uji lanjut menggunakan DMRT 5%. Hasil penelitian menunjukkan bahwa penambahan BAP pada media MS berpengaruh pada pertumbuhan kalus kultur jaringan tanaman porang berdasarkan uji one way ANOVA. Konsentrasi 2 mg/L BAP merupakan konsentrasi yang paling cepat dalam menginduksi pertumbuhan kalus dengan rata-rata waktu pelengkungan kalus 1,450 mst dan rata-rata waktu munculnya kalus 2,633 mst.Kata Kunci: induksi kalus; BAP; Amorphophallus muelleri.
