Abstract

Lansium domesticum Corr. is called Duku, an endemic Indonesian plant whose fruit has commercial value. The formation of the seeds of this plant takes a relatively long time (±15 years) for conventional propagation. Micropropagation with plant tissue culture techniques can be a solution. In the first phase of micropropagation, optimization of the type and concentration of growth regulators for callus induction is needed. This study aimed to determine the response of various types of duku explants (such as leaves, petioles, and mother petioles) to combinations of growth regulators (such as 0 ppm 2,4-D + 0 ppm BAP; 0.75 ppm 2,4-D + 0, 5 ppm BAP; 0.75 ppm 2,4-D + 0.75 ppm BAP; 0.75 ppm 2,4-D + 1 ppm BAP) in callus induction. The explants were cultured on Wood Plant Medium (WPM) with 30 g sucrose and 8 g agar for 28 days. The results showed that the concentration of 0.75 2,4-D + 0.75 BAP with leaf stalk mother explants was the best for callus formation. The characteristics of the callus formed were white-yellow with a compact texture. Keywords : Lansium domesticum Corr., Callus induction, Growth regulators, Types of explants.

Abstract

Duku (Lansium domesticum Corr.) is an endemic plant of Indonesia that has a distinctive taste and is beneficial in the health sector. Besides that, the demand for duku seeds is increasing, so it is proven by the rapid propagation technique on a large scale. This can be achieved through tissue culture techniques. This study aimed to determine the effect of the growth regulators 2,4-D and BAP on Folium explants and Petiolus communis explants in inducing shoots. Leaf explants and leaf stalks were initiated using WPM (Woody Plant Medium) media with 4 different combinations of concentrations of growth regulators 2,4-D and BAP consisting of 0.0 ppm (2.4-D) + 0.0 ppm (BAP); 0.2 ppm (2.4-D) + 2.0 ppm (BAP); 0.2 ppm (2.4-D) + 2.5 ppm (BAP); 0.2 ppm (2.4-D) + 3.0 ppm (BAP) -D) + 2.0 ppm (BAP) on Petiolus communis explants is the most optimal combination of growth regulators, this is indicated by the growth response of the explants, namely the formation of brownish yellow callus on the explants.

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

The Rutaceae famili is a citrus plant that is spread throughout Indonesia. These plants are rich with vitamin C, folate and fiber. Rutaceae members have not been well identified until now, especially in the Sriwijaya Botanical Gardens. This research aims to determine various species of plants in the Rutaceae family in the Sriwijaya Botanical Gardens. This research is a qualitative descriptive study. Data collection was carried out by direct exploring inside the Sriwijaya Botanical Gardens. The results found five species of the Rutaceae family, such as jeruk nipis or lime (Citrus aurantiifolia), jeruk kunci or calamansi (Citrus microcarpa), gongseng or orange berry (Glycosmis pentaphylla), sampang or euodia lunu-ankenda (Melicope lunu-ankenda) and kemuning or orange jasmine (Murraya paniculata).
