UJI KETURUNAN PULAI DARAT (Alstonia angustiloba Miq.) UNTUK MENDUKUNG PENYEDIAAN SUMBER BENIH UNGGUL
Isi Artikel Utama
Abstrak
Penelitian ini bertujuan untuk mengetahui persen hidup, tinggi tanaman, dan diameter batang tanaman uji keturunan
pulai darat umur 2 tahun dalam rangka mendukung penyediaan sumber benih unggul. Rancangan percobaan yang
digunakan adalah Randomized Complete Block Design (RCBD) yang terdiri atas 2 faktor, yaitu tempat asal populasi
(A) dan pohon induk (B). Dalam penelitian ini faktor B bersarang (nested) dalam faktor A. Faktor A terdiri atas 4
tempat asal populasi (Carita-Banten, Pendopo-Muara Enim, Lubuk Linggau-Musi Rawas dan Solok-Sumatera Barat)
dan faktor B terdiri atas 43 pohon induk. Hasil penelitian menunjukkan bahwa persen hidup, tinggi tanaman dan
diameter batang tanaman uji keturunan pulai darat umur 2 tahun di Wonogiri berturut-turut sebesar 82,07 %; 2,43 m
dan 2,85 cm.
