| dc.description.abstract | This study aims to determine the effect of using the growth regulator 2,4-D
and the growth regulator BAP as well as the interaction of the combination of2,4-
D and BAP on the growth of Cumin Leaves (Coleus amboinicus L.) shoots in
vitro. This research was carried out at the Biotechnology Laboratory, Faculty of
Agriculture, University of North Sumatra from January 2024 to April 2024. This
research used the Completely Randomized Design (CRD) method with 2 treatment
factors and each treatment had 3 replications. The first treatment factor is the
ZPT concentration of 2.4 D which consists of O ppm, 0.5 ppm and 1 ppm. The
second treatment factor is the ZPT BAP concentration which consists of O ppm, 2
ppm and 4 ppm. The parameters observed were the percentage of exp/ants
forming shoots(%), the percentage of exp/ants forming callus (%), shoot length,
shoot emergence time, and leaf emergence time. The results of this study showed
that giving BAP had a significant effect on observing the length of shoots and the
time of shoot emergence. The application of 2.4-D had no significant effect on the
parameters of shoot Length and time of emergence of black cumin shoots. The
interaction of the combination of 2,4-D and BAP had no significant effect on the
parameters of shoot length and shoot emergence time.
Keywords: 2.4-D, BAP, cumin leaves, shoot culture, tissue culture
