Abstract

Tanaman teh (Camellia sinensis) dapat menghasilkan bunga dan biji, yang dapat dimanfaatkan oleh pemulia tanaman dalam proses persilangan buatan. Pemulia dapat memprediksi keberhasilan persilangan buatan dengan menganalisis keragaman genetik tetua yang akan disilangkan. Tujuan penelitian ini adalah untuk mengetahui keragaman genetik aksesi teh dari benih illegitim pada masa reproduksi. Penelitian dilaksanakan mulai bulan Agustus 2023 sampai dengan Januari 2024 di Pusat Penelitian Teh dan Kina, Desa Mekarsari, Kecamatan Pasir Jambu, Kabupaten Bandung. Metode penelitian yang digunakan yaitu rancangan tanpa tata ruang. Sebanyak tiga belas aksesi terpilih pada populasi saat periode berbunga diidentifikasi penampilan morfologinya sejumlah 15 karakter. Data hasil pengamatan digunakan untuk menganalisis analisis komponen utama dan analisis klaster menggunakan software XLSTAT, sedangkan visualisasi data menggunakan R Program. Hasil yang diperoleh menunjukkan bahwa bahwa 13 aksesi teh mempunyai keragaman genetik yang tinggi. Hasil tersebut berlandaskan keragaman genetik pada 5 komponen utama yang mencapai 89.11% dan analisis klaster yang terbagi menjadi 3 klaster utama dengan persentase terbesar pada klaster ketiga yaitu sebesar 46.15%.

Abstract

The growth of immature Cinchona ledgeriana can be optimized by applying fertilizers to fill the nutritional needs of plants. Nutrients can be provided through the help of microorganisms derived from organic fertilizers and biofertilizers. This study aims to evaluate the effect of applying coffee husk compost and biofertilizer consortium on the growth of immature quinine plants. This research was conducted from November 2023 – January 2024 at Gambung Tea and Cinchona Research Center, Pasir Jambu District, Bandung Regency, West Java. The research used a randomized block design with four replications and six treatments, namely control (Urea 17 g.plant-1 + SP36 8 g.plant-1 + KCl 4 g.plant-1); solid coffee husk compost 3 kg.plant-1; liquid coffee husk compost 80 mL.L-1; biofertilizer 10 mL.L-1; solid coffee husk compost 3 kg.plants-1 + biofertilizer 10 mL.L-1; and liquid coffee husk compost 80 mL.L-1 + biofertilizer 10 mL.L-1. The results showed applying organic fertilizer from coffee husk waste and biofertilizer improved the growth of immature quinine plants. Combination of liquid organic fertilizer from coffee husk waste 80 mL.L-1 water + biofertilizer 10 mL.L-1 water produced a high increase in leaf area. Combination of solid organic fertilizer from coffee husk waste 3 kg. plants-1 + biofertilizer 10 mL.L-1 water showed the highest plant height increment. It implied the success of quinine improvement growth at the immature phase by applying coffee husk waste and biofertilizers.
