    Barangan banana (Musa acuminata L.) is a plant that has the biggest contribution to national fruit production. The increasing demand for the banana requires the availability of seedlings, while conventional cultivation is unable to produce healthy, disease-free seedlings in a short time and large amount. In vitro culture is considered to be able to handle the constraints of the conventional seed supply.  The purpose of this study was to determine the effect of foliar fertilizers on in vitro multiplication of barangan bananas. The method used was a single factor of Completely Randomized Design (CRD), the addition of leaf fertilizer consisting of five levels of media treatment, media MS (control), and 0.50 ml L-1 (p1); 0.75 ml L-1 (p2); 1.00 ml L-1 (p3); 1.25 ml L-1 (p4); 1.50 ml L-1 (p5) of leaf fertilizer media repeated five times. The data were analyzed with Analysis Variance then followed by Duncan Multiple Ranged Test of 5%. The results showed MS media still gave the best results compared to other leaf fertilizer media. Meanwhile, the leaf fertilizer media used in this study still gave good results on the initial time of buds appearance (p3 treatment), the number of shoots and the number of leaves in the p5 treatment, as well as the height of the plant in the p4 and p5 treatments. Therefore, the leaf fertilizer can be used to substitute MS mediaBarangan banana (Musa acuminata L.) is a plant that has the biggest contribution to national fruit production.

    Genetic enhancement in vegetatively propagated crops can be done through mutation induction. Colchicine-induced mutation is one of the methods that can be employed to increase plant genetic diversity. This study aimed to determine the effect of colchicine on the performance and genetic parameters of MV3 generation of Plectranthus amboinicus (L.). This study was conducted at the Laboratory of Agricultural Seed Management, Plantation Research and Development Center, from June 2018 to June 2019. Nodes and shoots were used as explants. Mutation induction was performed using colchicine at concentrations of 0%, 0.02%, 0.04%, and 0.06%. Explant regeneration and subculture were done on MS0 medium. The number of plantlets yielded were 59 (0% concentration of colchicine), 60 (0.02%), 81 (0.04%), and 80 plantlets (0.06%), respectively. Results indicated that colchicine-induced mutation in an in vitro culture was able to generate high genetic diversity in both quantitative and qualitative characters of the plantlets. At the concentration of 0.04%, colchicine produced the highest frequency of putative mutants (28.4%). Genetic parameters in MV3 generation of P. amboinicus plantlets showed that five quantitative characters, i.e. plantlet height, number of leaves, number of shoots, leaf length, and number of roots had high heritability values at a concentration around the LC50 value (0.0275%)
