Abstract

Coffee is a plantation commodity which important to increase its production, such as by vegetative propagation i.e., shoot cuttings that stimulated by Plant Growth Regulators (PGR). The research was on the effect of Rootone F concentrations on roots and shoots induction of Arabica coffee (Coffea arabica) shoot cuttings, it was carried out at the smallholder coffee plantation Solok Radjo in Aie Dingin Village, Lembah Gumanti District, Solok Regency on April until August 2022. The objectives of this study were to determine the growth response of Arabica coffee shoot cuttings on the induction of the roots and shoots, and to determine the best concentration of Rootone F PGR on the growth of it. This study was designed by a Completely Randomized Design (CRD) with 6 concentrations of Rootone F, namely: 0, 200, 400, 600, 800, and 1000 ppm. The observed variables were percentage of live cuttings, first shoots emergence, longest root and shoot, number of roots and shoots, and fresh weight of roots. The obtained data were analyzed of variance at the 5% level and if it was significantly different continued by Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results showed that there was a shoot cuttings growth response of Arabica coffee on the variable of percentage of living cuttings, first shoots emergence, longest root and shoot, and fresh weight of roots, except on the variable number of roots and shoots. The best concentration of Rootone F PGR on the roots and shoots induction of Arabica coffee shoot cuttings in supporting its growth was 400 ppm.

Abstract

Varietas semangka hibrida memiliki produktivitas dan keseragaman yang tinggi sehingga diminati oleh konsumen. Penelitian ini bertujuan untuk mengevaluasi beberapa hibrida hasil persilangan antara galur inbrida dengan varietas Serif Saga Agrihorti (SSA) sebagai tetua jantan. Percobaan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan, melibatkan 12 hibrida hasil topcross dan Serif Saga Agrihorti (SSA) sebagai satu varietas pembanding. Semua genotipe ditanam di lapangan dengan mengikuti praktik agronomi semangka yang standar. Karakteristik yang diamati meliputi waktu berbunga jantan dan betina, umur panen, serta diameter dan bobot buah, ketebalan kulit buah, tingkat kemanisan, dan jumlah biji fertil dan biji steril. Data dianalisis menggunakan ANOVA dilanjutkan dengan uji BNT (Beda Nyata Terkecil). Variabilitas genotipik dan fenotipik, heritabilitas dan koefisien korelasi genotipik dan fenotipik  karakter, diestimasi berdasarkan partisi nilai ragam dari ANOVA. Hasil penelitian menunjukkan variabilitas genetik yang luas pada karakter umur berbunga jantan dan betina, serta bobot buah. Nilai duga heritabilitas yang tinggi diperoleh pada karakter umur berbunga jantan dan betina, bobot buah, diameter buah dan jumlah biji fertil. Empat genotipe hibrida yaitu G1, G6, G8, dan G10, menunjukkan bobot buah dan tingkat kemanisan yang lebih tinggi dibandingkan varietas SSA. Berdasarkan heritabilitas yang tinggi pada karakter bobot buah, maka keempat hibrida ini berpotensi untuk dikembangkan menjadi varietas semangka hibrida baru atau dimanfaatkan sebagai populasi dasar untuk perakitan varietas bersari bebas.
