PENGARUH BENZILAMINOPURIN DENGAN PENAMBAHAN KNO3 PADA MULTIPLIKASI TUNAS Colocasia esculenta (L.) Schott VAR. Antiquorum
Abstract
Talas satoimo merupakan makanan sumber karbohidrat, kebutuhannya melebihi kapasitas produksi sehingga memiliki peluang besar di pasaran. Perbanyakan tunas memberikan alternatif untuk memenuhi tuntutan pasar. Melalui penggunaan benzilaminopurin dan kombinasi KNO3 diharapkan dapat mengetahui media optimal bagi perbanyakan tunas talas satoimo. Penelitian ini dilaksanakan di Balai Bioteknologi, BPPT, Setu, Tangerang Selatan dengan metode penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial yg terdiri dari 2 faktor, yaitu faktor pertama konsentrasi KNO3 0, 300, 600 dan 1200 ppm dan faktor kedua konsentrasi BAP 0; 0.2; dan 0.6 ppm. Media dasar menggunakan Murashige-Skoog (MS). Pengamatan dilakukan setiap minggu selama 6 minggu setelah tanam (MST). Hasil pengamatan menunjukkan bahwa perlakuan BAP 0.6 ppm dengan penambahan KNO3 300 ppm optimal bagi perbanyakan tunas.
ABSTRACT
Talas satoimo is a carbohydrate source, the production capacity less than necessary so it has potential market. Shoot multiplication provide alternative to supply demand market. Through use of Benzylaminopurine and combination KNO3 will discover optimal medium for shoot multiplication. This study conducted at Research Center for Biotechnology, BPPT, Setu, Tangerang Selatan. The method using complete random factorial design consisted of two factor that is concentration combination KNO3 at 0, 300, 600 and 1200 ppm and Benzylaminopurine at 0, 0.2, 0.6 ppm. The basic media using Murashige-Skoog (MS). Observation were set every weeks during six weeks after planting. The optimal growth was obtained at MS medium containing Benzylaminopurine 0.6 ppm in combination with KNO3 300 ppm.
