Abstract

Exploitation on plant population may put the endemic plants into an endangered state, hence, these plants will need to be conserved. In order to pursue conservation on endemic plants, we conducted in vitro seed germination and shoot multiplication of seven alpine and sub-alpine species endemic to Mount (Mt.) Jaya, in Papua, Indonesia, i.e. Tetramolopium klossii, Deschampsia klossii, Papuacalia cartenszensis, Epilobium hooglandii, Gaultheria novoguinensis, Rhododendron correoides and Rhododendron culminicolum. These species are categorized as slow-growth plants found in higher altitude (over 3700 m above sea level) and low temperature of Mt. Jaya. Seeds were surface-sterilized using Na-hypochloride and germinated aseptically on Murashige and Skoog (MS) medium. Dytikinin benzyl adenine (BA) was used for shoot multiplication. Seedling cultures were maintained in a controlled environment with  continuous low light intensity (800 lux) and at temperature 26-27oC. Results showed that most species had more than 80% of germination rate on MS medium after a week in culture. BA was required to enhance shoots multiplication. Woody Plant (WP) (Lloyd & McCown, 1981) medium gave better shoot multiplication for R. culminicolum.

Abstract

ABSTRACTChromosome number analysis is required after polyploid induction with oryzalin. Flowcytometry analysis is a simple and quick method to determine the ploidy level, however, chromosome number analysis is needed in order to confirm variation in the chromosome numbers which has occurred. The aim of the research was to investigate chromosome number variation of polyploid taro (Colocasia esculenta) after in vitro treatment with oryzalin. Nine treated-oryzalin clones and four taro cultivars, as control treatment, were used in this experiment. Ploidy level confirmation was done by flowcytometry analysis, meanwhile chromosome number calculation was performed by squashing method. Roots were isolated from  in vitro plantlets for squashing, leaves were isolated from the same plantlets were used for flowcytometry analysis. At least three plants consisted of 6-52 cells having good chromosome distributions were calculated for their chromosome numbers. The results showed that ploidy level of taro corresponded to the number of chromosomes. Flowcytometry analysis of diploid, triploid, tetraploid as well as hexaploid clones, all has chromosome numbers similar to those as their ploidy levels. Range of the chromosome numbers varied, with most of cells had around their normal chromosome numbers. From 5 to 15% of cells had aneuploid numbers lower or above their normal chromosome numbers.  Keywords : Colocasia esculenta, flowcytometer, polyploid, chromosome number, oryzalin, in vitro

Abstract

ABSTRACTGenetic improvement through tetraploid induction of Stevia rebaudiana is important in order to increase the sweetener content, steviol glycoside. Tetraploid plants of several species after induction with colchicine and oryzalin have higher growth and secondary metabolite contents compared to the diploid plants. This study was aimed to evaluate growth as well as their stevioside and Reb-A content of S. rebaudiana tetraploid and diploid (control) plants cultured in vitro and grown in the field after acclimation process. This study used 3 tetraploid clones, namely B60.3H8, P1T22, P3T5, and 1 diploid clone as control. Shoot tips were cultured on MS medium without addition of plant growth regulators for 6 weeks, then they were acclimated in a greenhouse, followed by planting them in the field. Growth of shoot culture, plantlets in the greenhouse and plants in the field were observed. Analysis of stevioside and Reb-A was done by HPLC. The results showed that plantlets of diploid clone had higher in vitro growth and survival rate in the greenhouse than that of tetraploids. Tetraploid clone P1T22 had similar growth as diploid plants, but higher than the growth of tetraploid B60.3H8 and P3T5. Fresh and dry weights of B60.3H8 was similar with diploid plants, but higher than P1T22 and P3T5 tetraploid clones. The highest level of stevioside and Rebaudiosida-A was found in tetraploid B60.3H8 clone, the lowest was found in the diploid plants. The highest ratio of stevioside : Reb-A was found at B60.3H8 tetraploid clone.  Keywords: Stevia rebaudiana, in vitro, field, growth, Stevioside, Rebaudioside-A, tetraploid

Abstract

The mother plant and genetic variability of Indonesian mango need to be conserved. Encapsulation is one of in vitro conservation used for many plant species. The aim of this research was to study the regeneration of encapsulated mango cultivar Bapang and Gadung 21 embryogenic callus after storage at -14, 3?5, and 26?27oC for 0, 1, 2, 4, and 8 weeks. Embryogenenic callus was treated with 3% Na-alginate (in liquid 3M), then it was dropped into 100 mM CaCl2. Encapsulated callus beads were dehidrated and stored at -14, 3?5, and 26?27oC for 0, 1, 2, 4, and 8 weeks. After storage, the callus was cultured in 3M medium containing 2,4-D at 0, 1, and 2 mg/l for the regeneration. The results showed that after 8-week storage, callus of Bapang culticar was more viable (67.3%) and resulted more number of somatic embryos (191.6%) than Gadung 21 cultivar. The callus which was cultured in 3M medium without addition of 2,4-D was more viable (20.9%) and had more number of somatic embryos (1062.5%) than that which was cultured on medium containing 2,4-D. After 2-week storage, callus had viability of 7.6%. No storage callus formed more somatic embryos than storage callus. Storage at 26?27oC gave higher viability as well as higher number of somatic embryo than stored at -14 and 3?5 oC. The callus did not regenerate into shoots after storage at -14oC. Embryogenic callus could be stored at 3?5 and 26?27oC for 4 weeks.

Abstract

The aim of this study was to investigate the effect of rootstock and shoot types on in vitro mangosteen micrografting.The experiment was arranged in completely randomized design (CRD) with two factors. The first factor was the rootstocktype, i.e. rooted planlet from the germination of quartered seed, and rooted planlet from the germination of undivided seeds.The second factor was the developmental phase of scion, i.e. dormant buds, and flush (had new leaf more than 2-4 mm). Theresults showed that rootstock derived from the germination of undivided seed had a higher success rate than other treatmentson all variables, except for number of new leaves. The use of flush as scion was better than dormant buds; flush resulted in ahigher percentage of successful micrograft and longer shoots. In vitro micrografting had a better growth rate than grafting at the same age. The results of anatomical observation conducted at four months after micrografting demonstrated that there was a good graft union, indicated by excellent fusion between rootstock and scion xylem tissues.Keywords: flush, in vitro, micrografting, rootstock, scion
