Abstract

Penelitian ini bertujuan untuk mengetahui konsentrasi dan frekuensi pemberian paclobutrazol yang efektif serta pengaruhnya terhadap pembungaan Dendrobium ‘Arirang Green’. Penelitian dilaksanakan di halaman belakang Bima Utomo Waterpark Jl. Ampera pasar 6 Batang Jambu, Desa Sidodadi, Kec. Batang Kuis, Kabupaten Deli Serdang, Sumatera Utara, dari Februari hingga April 2021. Penelitian dirancang secara acak lengkap (RAK) faktorial yang terdiri atas 2 faktor dan 3 kali ulangan. Faktor pertama adalah konsentrasi paclobutrazol (0; 25; 50; 75 ppm) dan faktor kedua adalah frekuensi pemberian paclobutrazol (seminggu sekali dan dua minggu sekali). Pengamatan dilakukan seminggu sekali, 1 minggu setelah perlakuan paclobutrazol, yang meliputi waktu kemunculan kuncup, persentase tanaman berkuncup, waktu kemunculan bunga, persentase tanaman berbunga dan jumlah bunga. Data kemudian dianalisis dengan sidik ragam dan uji BNT. Hasil penelitian menunjukkan perlakuan 50 ppm + dua minggu sekali (A2B2) merupakan perlakuan terbaik dengan rata-rata waktu berkuncup 5 MST; persentase berkuncup 75%; rata-rata waktu berbunga 7,5 MST; persentase berbunga 50%, dan rata-rata 5 bunga. Konsentrasi pemberian paclobutrazol terhadap waktu munculnya kuncup bunga tanaman Anggrek D. ‘Arirang Green’ memberikan pengaruh yang berbeda nyata terhadap waktu kemunculan kuncup, namun tidak berpengaruh nyata terhadap waktu kemunculan bunga.
