Induksi Pertumbuhan Eksplan Endosperm Ulin dengan IAA dan Kinetine

Abstract

The aims of this research for examining the effect of concentrations of Indole Acetic Acid (IAA) and Kinetine on
the growth of ulin. The research using Murashige and Skoog medium was conducted in Biotechnology Laboratory
of Agriculture Faculty, Tanjungpura University from June 2003 to May 2004. All treatments were arranged in
randomized complete design with ten treatments and four replications. The variable of this research was scoring on
callusformation, time of callusformation (days) and number of callus. The result showed that (5.0 ppm IAA + 6.0
ppm Kinetine) and (6.0 ppm IAA + 5.0 ppm Kinetine) were better concentration combination for callus induction.
The better for time of callusformation and numbers of callus were 5.0 ppm IAA + 6.0 ppm Kinetine.
