Young leaf segments from mature oil palm were cultured on MS medium supplemented with different concentrations of 2,4-D with or without addition of 2 g/l activated charcoal (AC) or 2,4-D and picloram. Embryogenesis induction was done using MS medium containing 2,4-D 450 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M and benziladenine 4.4 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M with 3g/l activated charcoal. The treatment of 2,4-D 15 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M resulted in the highest percentage of callus induction. The treatment of 2,4-D and AC showed that 2,4-D 450 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M and AC led to higher percentage of callus induction than that of 2,4-D 400 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M and 2 g/l AC. Embryogenesis occured in 27 out of 250 clumps of primary callus was occurred after 2-3 times subcultures. Somatic embryo development occurred when the embryogenic callus was transferred on the same basal medium supplemented with casein hydrolysate with 1 </span></strong><strong><span style="font-size:9pt;font-family:Symbol;">m</span></strong><strong><span style="font-size:9pt;">M BA or growth regulator free basal medium with 2 g/l activated charcoal.</span></strong></p> Download Download PDF
