Abstract

Aglaonema sp. is well known as an ornamental plant in Indonesian society. It has leaf with various beautiful patterns. Aglaonema pink katrina is one of the imported hybrids Aglaonema. A method to increase plant yield quickly is tissue culture. The crucial step in plant tissue culture is sterilization. This study aimed to find the best sterilization method by looking at the effect of concentration and immersion time of sodium hypochlorite (NaOCl) as disinfectant to reduce contaminants explant Aglaonema Pink Katrina leaves. In this study, there were 11 groups consisting of positive control, negative control, and immersion with 2,5; 5%; and 10% NaOCl for 1 minute and 3 minutes. Parameters observed included the time of first contamination, percentage of bacterial and fungal contamination, and appearance of explants for 28 days. The DMRT test showed significant differences in all treatments of disinfectant concentration and soaking time.The results show contamination first time occurred in code S0a (negative control), the highest percentage of sterile explants was in code A5, and explants that were still green/fresh were found in codes A5 and A8 after observation.

Abstract

Pterocarpus indicus Willd. also known as redwood is a native Philippine species belonging to the Fabaceae family that has many uses and high economic value and highly exploited. However, it is not accompanied by good regeneration which causes this species to be categorized as endangered (IUCN v. 2021-1). The in vitro technique is an alternative to overcome this problem. This study aims to determine the response of P. indicus Willd. shoot growth to the addition of BAP and TDZ in vitro. The research was conducted from August to December 2023, at the Biotechnology Laboratory, KST BJ. Habibie Puspiptek Serpong, South Tangerang, Banten. This study used a completely randomized design (CRD) consisting of 9 treatments and 14 replications. The treatments consisted of: R0 = Control, R1 = BAP 0,25 ppm, R2 = BAP 0,5 ppm, R3 = BAP 0,75 ppm, R4 = BAP 1 ppm, R5 = TDZ 0,25 ppm, R6 = TDZ 0,5 ppm, R7 = TDZ 0,75 ppm, R8 = TDZ 1 ppm. The results showed that the concentration of BAP 0,5 ppm gave the best results in height of shoot and TDZ 0,25 ppm gave optimum results in the number of shoots compared to the control and other treatment concentrations.

Abstract

ABSTRACTThe improvement of Mangifera indica L. by conventional breeding approaches has been confounded by the long generation cycle, low fruit set, single seed per fruit and high degree of cross pollination. Biotechnology complements conventional breeding and expedite the mango improvement programs. Endosperm culture is a direct method to produce triploid plants. This study aimed  to obtain embryo from endosperm culture. The system of secondary somatic embriogenesis in mango described here represents a source of embryogenic material may be used for mass propagation and genetic manipulation of this crop. The method consisted of induction, proliferation, maturation, germination, and histological analysis of the obtaimed embryos. A protocol for plantlet regeneration was developed for Gedong Gincu mango clone 289 through secondary somatic embryogenesis. Primary somatic embryos (proembryo and cotyledonary embryos) were cultured in induction medium to induce the secondary somatic embryos. The best proliferation rate was 0.22 in medium with 1 g L-1 Poly Vinyl Pyrrolidone (PVP) for multiplication of secondary somatic embryos. Maturation of inoculum derived from the proliferation medium supplemented with 2 g L-1 of activated charcoal on medium containing 0.4 mg L-1 BAP provides the average 2.39 embryo formation of cotyledonari phase. The highest germination frequency (20%) was obtained in media with GA3 1.5 mg L-1.Keywords: endosperm, Gedong Gincu, Mangifera indica L, secondary endospermic embrio
