Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh jenis dan konsentrasi vitamin terhadap pertumbuhan dan perkembangan biji anggrek Dendrobium laxiflorum secara in vitro. Penelitian dirancang dengan menggunakan Rancangan Acak Lengkap 2 Faktorial. Faktor pertama adalah jenis vitamin yang terdiri dari thiamin, niasin dan piridoksin sedangkan faktor kedua adalah konsentrasi vitamin yang digunakan adalah 0 ppm; 0,1 ppm; 0,3 ppm; 0,5 ppm. Pengamatan dilakukan setelah 3 bulan. Hasil penelitian menunjukkan bahwa total persentase pertumbuhan dan perkembangan biji D. laxiflorum berkisar antara 2,48%-75,66%. Hasil uji ANOVA menunjukkan bahwa jenis vitamin dan konsentrasi vitamin berpengaruh terhadap pertumbuhan dan perkembangan biji D. laxiflorum (P≤0,05). Berdasarkan hasil uji ANOVA tidak ada interaksi antara jenis dan konsentrasi vitamin
