Abstract

The purpose of this study was to determine the best basic medium type and TDZ concentration for the development of somatic embryos from Dendrobium orchid leaf explants. Three replications were arranged factorial (2x3) in a completely randomized design for this study. First, there were two types of basic media, ½ MS and MS. The second factor was the concentration of cytokinin thidiazuron 1, 2 and 3 mg/L. Each experimental unit consisted of 5 culture bottles, each contained 5 explants. The research results showed that 1) The use of both types of basic media was able to induce callus formation on Dendrobium 'Gradita 31' orchid from leaf explants. 2) The use of 3 mg/L thidiazuron which combined with ½ MS or MS media was able to form primary callus faster than other treatments. 3) The higher percentage for embryo somatic and shoots formation were also found in 3 mg/L thidiazuron.

Abstract

Conventional breeding methods of chrysanthemum plants face several challenges to overcome, and physical mutagens such as gamma rays have proven effective in creating chrysanthemum mutants. As an important tool in flower germplasm innovation and variety improvement, gamma rays have greater penetrating power compared to other breeding methods. This research aims to determine the effect of various doses of gamma irradiation on chrysanthemum callus growth, plant regeneration, and morphology due to induction and to determine the existence of genetic variations using ISSR markers. The experiment consisted of four stages, namely, chrysanthemum callus explants were irradiated at doses of 0, 10, 20, and 30 Gray using gamma rays to induce mutations and observe the effect on callus growth. The irradiation results were planted in BA media 0.5, 1.5, and 3.0 mg L-1 to observe shoot growth. Next, the shoots were planted in rooting media containing NAA with and without activated charcoal (AC) for plant regeneration and amplification of chrysanthemum genomic DNA. The results showed that a lower radiation dose (10 Gray) had a positive influence on all growth parameters, while 30 Gray caused a significant reduction in plant height and number of leaves. NAA 1 mg L-1 AC 2 mg L-1 media gave the best results in supporting the growth of chrysanthemum plants at various levels of radiation exposure. Analysis using ISSR markers confirmed the presence of genetic variation in irradiated plants.

Abstract

Tissue culture can be used as an alternative technique that can be used to multiply porang seeds to meet the need for seeds in porang development. This study aims to determine the proliferation response of porang in various types and concentrations of BAP or TDZ. The experiment was carried out using a randomized block design (RAK). The treatments tried in the shoot proliferation experiment were P1 (MS 0), P2 (BAP 0.5 mg.l-1), P3 (BAP 1 mg.l-1), P4 (TDZ 0.5 mg.l-1) and P5 (TDZ 1 mg.l-1). Each treatment was tried with 5 replications, and each treatment per replication was planted with 5 bottles. Data were analyzed by Analysis of Variance, and differences between treatments were seen by the LSD test at the 5% level. The use of MS 0 and BAP 1 mg.l-1 gave better results compared to other treatments. The use of MS 0 and BAP 1 mg.l-1 resulted in 100% shoot growth on porang propagules. MS 0 and BAP 1 mg.l-1 produced the highest number of shoots (17.8 and 17.4) and the highest shoot height (3.52 and 2.50) compared to the other three treatments.

Abstract

The limited availability of conventional porang seedlings through seeds and tubers is a constraint in the development of this plant because it is time-consuming, seasonal-dependent, and produces non-uniform seedlings. Therefore, an alternative method in the form of tissue culture, known as micropropagation, is needed to produce quality porang seedlings. Micropropagation is a more efficient and profitable plant propagation method than conventional methods because it can produce seedlings in a relatively short time, is not seasonal-dependent, uniform, and free from pathogens. This study aims to determine the response of porang shoot multiplication to various types and concentrations of cytokinin growth regulators. The experiment was conducted using randomized block design. The treatments tested were P1 : BAP 0 mg.l-1 + TDZ 1 mg.l-1 ; P2 : BAP 0 mg.l-1 + TDZ 2 mg.l-1 ; P3 : BAP 0 mg.l-1 + TDZ 3 mg.l-1 ; P4 : BAP 1 mg.l-1 + TDZ 0 mg.l-1 ; P5 : BAP 1 mg.l-1 + TDZ 0,5 mg.l-1 ; P6 : BAP 1 mg.l-1 + TDZ 1 mg.l-1 ; P7 : BAP 2 mg.l-1 + TDZ 0 mg.l-1 ; P8 : BAP 2 mg.l-1 + TDZ 0,5 mg.l-1 ; P9 : BAP 2 mg.l-1 + TDZ 1 mg.l-1 ; P10 : BAP 3 mg.l-1 + TDZ 0 mg.l-1 ; P11 : BAP 3 mg.l-1 + TDZ 0,5 mg.l-1 ; dan P12 : BAP 3 mg.l-1 + TDZ 1 mg.l-1. Each treatment was replicated five times, with five bottles planted in each replication. Data were analyzed using Analysis of Variance, and differences between treatments were assessed using the LSD test at the 5% level. The observed variables were the rate at which explants formed buds, the number of buds, and the multiplication rate. Addition of cytokinin affected the multiplication response of porang buds in vitro. The P6 treatment produced the fastest bud formation rate, the highest number of buds and the highest multiplication rate.
