Abstract

The ginger plant is known for its healing and warming properties because it contains various bioactive compounds that provide numerous therapeutic benefits. However, the quality of ginger production has declined due to disease infections. To address this issue, tissue culture techniques are being employed. The purpose of this study was to obtain high-quality ginger planting materials. This research was conducted at MARDI Malaysia, utilizing a completely randomized factorial design consisting of 2 factors. The first factor is hormones comprised of five levels, namely H 1 = GA 3, H 2 = IAA, H 3 = IBA, H 4= NAA and H 5 = BAP The second factor of hormone concentration, consists of five levels, K 1 = control, K 2 = 0.5 ppm, K 3 = 1 ppm K 4 = 1.5 ppm and K 5 = 2.5 ppm. The results of the study showed that the treatment of NAA concentration2.5 ppm had a significant effect on plant height, GA 3 treatment at a concentration of 0.5 ppm, IAA at a concentration of 2.5 ppm, IBA and BAP at a concentration of 1 ppm had a significant effect on the number of leaves, GA 3 treatment at a concentration of 0.5 ppm, IAA at a concentration of 2.5 ppm, IBA and BAP at a concentration of 1 ppm had a significant effect on the number of leaves,0.5 and 1ppm had a significant effect on root length, NAA treatment at concentrations of 0.5 and 1ppm had a significant effect on the number of roots, GA 3 treatment at concentrations of 0.5 ppm had a significant effect on wet weight. root.
