Efek NAA dan BAP terhadap Pembentukan Tunas, Daun, dan Tinggi Tunas Stek Mikro Nepenthes ampullaria Jack.
Abstrak: This study aimed to
know the interaction between NAA and BAP as well as to obtain the best
combination of both treatments in promoting the growth of Nepenthes
ampullariamicrocutting.An experiment arranged in a factorial Randomized
Complete Block Design (RCBD) wasapplied. Stem segments were used as blocks,
where block I was the first segment followed by the next two segments as block
II and III respectively. Two factors, i.e. NAA concentrations (0, 5, 10, 15 µM)
and BAP concentrations (0, 9, 18, 27 µM) were employed giving rise to 16
combination of treatments. Each treatment combination was replicated threetimes
resulting in 48 experimental units. The parametersmeasured were date of shoot
initiation, date of root initiation, shoot number, leaf number, root number,
length of longest leafand shoot height. The results showed that
interactionbetween NAA and BAP in promoting N. ampullariamicrocutting growth
was observed. Combination between NAA of
0 µM and BAP of 18 µMwas found to be the best in promoting N. ampullariamicrocutting
growth.Meanwhile, combination between NAA 0 µM and BAP 27 µM was recommended to
promote shoot number of N. ampullaria.
