Abstract

Zingiberaceae is a family of spice plants that are commonly found in the Sriwijaya Botanical Gardens, this type of plant is often used as medicine, cooking spices, ornamental plants and hair medicine. Families of Zingiberaceae are still not well identified. This study aims to determine the species of the Zingiberaceae families in the Sriwijaya Botanical Gardens. This research uses descriptive qualitative research and uses the method of exploring the location in the Kebun Raya Sriwijaya. The identification results obtained six species of plant species from the Zingiberaceae family, namely galangal: Alpinia galanga (L.) Wild., yellow turmeric: Curcuma longa L., kencur: Kaempferia galanga L., white turmeric: Curcuma zeodaria (Christem.) Roscoe., ginger white : Zingiber officinale var. amrum., and forest galangal : Alpinia malaccensis.

Abstract

Duku (Lansium domesticum. Corr) is one of the fruit plants that grows a lot in Indonesia, especially in South Sumatra. Duku fruit has a fairly high level of consumption but takes a long time to reproduce. Modern duku propagation is an effort that can be used to overcome problems that occur in conventional duku cultivation. One of the efforts to propagate duku in a modern way can be done through tissue culture techniques. Tissue culture techniques can produce plants in large quantities and have the same characteristics and characteristics as the parent. This research was conducted from September 2022 – November 2022, taking place in the tissue culture room, the Integrated Laboratory of Raden Fatah State Islamic University Palembang. This type of research is descriptive quantitative with experimental method using Completely Randomized Design (CRD) with 5 treatments (0.0 ppm, 1.0 ppm, 1.5 ppm, 2.0 ppm and 2.5 ppm) and 5 repetitions. This study was to determine the response of petiole and leaf bone explants to tuna induction by BAP hormone administration. The best research results were given a concentration of 1.0 ppm BAP with growth time at 7 HST with the formation of bulges (nodules) on the upper surface of the explants.

Abstract

Vanilla (Vanilla planifolia Andrews) is a plantation plant that is used for its fruit. Indonesia is one of the countries that exports vanilla and has climate factors that support increasing vanilla production to meet global demand, One of the efforts that can be made in vanilla propagation is through plant tissue culture. This research aims to induce calluses. This study used a Random Design using stem explants and several different hormone concentrations, namely: 0.0 ppm NAA and 0.0 ppm Kinetin, 1.0 ppm NAA and 0.5 ppm Kinetin, 1.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 0.5 ppm Kinetin, 2.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 2.0 ppm Kinetin. There was an effect on the administration of NAA and Kinetin on callus induction in the explants of the vanilla plant (Vanilla planifolia Andrews). It is based on the Anova one-way Hypothesis Test with a significance value of 0.000 (Asymp. Sig <0.05) then Ho was rejected and H1 was accepted. The optimal concentration to induce callus in stem explants is the administration of 1.0 ppm NAA + 0.5 ppm Kinetin with an average callus growth rate of 7 HST and a 100% callus growth percentage of explants.   Keywords: Vanilla, induction, callus, tissue culture, hormones
