Jatropha curcas L. is a potential source of a non-edible biofuel. Conventional propagation of J. curcas technique has some limitations. Somatic embryo can produce a large number of embryos and obtain a large number of plants all year round. Treatment of sucrose in combination with polyethylene glycol (PEG) was proven to enhance germination of somatic embryos in many plant species. The aim of the study was to investigate the effect of sucrose in combination of PEG on somatic embryo germination in J. curcas. Globular somatic embryos at 0.025-0.030 g fresh weight having 0.4-0.5 cm in diameter were grown on MS medium solidified with 3 g/l of Gelzan supplemented with sucrose at 20, 30, 40, and 50 g/l in combination with PEG at 0, 2.5, 5, 10, and 15%. Results showed that the best medium for germination of J. curcas somatic embryo cultures was MS medium supplemented with 20 and 30 g/l of sucrose in combination with 5% of PEG. The numbers of germinated embryos per clump had significant enhancement on those medium compared with the control (PEG free treatment) (2.65 to 5.65) and (2.55 to 5.50). In addition, those treatments resulted in the highest percentage of clumps forming germinated embryos (100%), with an average of normal germinated embryos at 94.163 and 96.065%. The addition of 40 and 50 g/l of sucrose in combination with 15% of PEG caused all embryos to fail at germinating.

Artemisia cina is a medicinal plant species producing bioactive compounds which are potential as antitumor, antifungal and antibacterial. The aim of this study was to analyze the stabililY of chromosome number in root cultures of A. cina. Transformed root culture was established by infection of leaves of A. cina with Agrobacterium rhizogenes strains 07-20001 . ATCC-15834. A4 and A. tumefaciens strain RlOOO . Roots isolated from glasshouse plants, plantlets grown in solid and liquid MS medium were utilized for investigation of chromosome examination of untransformed roots. Chromosome examination was conducted by squashing method and chromosome numbers were calculated under microscope. The .results showed that both untransformed and transforme root had instability in the chromosome number, but had the modal number of chromosome x=8 with the diploid number of 2n = 4x = 32. Roots isolated from glasshouse plants of A. Cina had 53.7% of cell with the diploid numbers of 2n = 32 and 46.3% of cells had chromosome numbers ranged from 2n = 12 to 2n = 64. Untransformed roots isolated from plantlets cultured in solid medw had only 36.1 % or cells with chromo orne number of 2n = 32, and unlran fomled ro t5 grown in liquid medium had 49.4% of cells with 2n = 32. The chromosome numbers of A. Cina transformed roots was affected by trains of Agrobacterium. Root transformed with the bacterium Strain 07 -20001 showed lhe highest in normal chromosome number of 2n = 32 (62.4%) followed by roots lransformed wiLll strains ATCC-15834 (61.9 %). R1000 (43.6%) and A4 (43.0%). The range of the chromosome number untransformed roots was from 2n= 17 to 2n=64 whilst that of transformed roots was from 2n= 1 l to 20=66

The aim of this research was to compare the reduction effect of sucrose or table sugar concentration on growth characteristics of red ginger cultured in MS liquid medium. Shoots of red ginger was cultured on MS liquid medium without addition of plant growth regulators, supplemented with 5, 10, and 20 g/l of sucrose or table sugar for 8 weeks. Resulted plantlets were acclimatized in a greenhouse to investigate their growth and survival rate. Numbers of stomata, chlorophyll concentration as well as cross section of leaves from plantlets grown in vitro were compared to those of transplants grown in the greenhouse. The results showed that the use of table sugar at concentration of 20 g/l gave the best growth of red ginger. Meanwhile, the reduction of table sugar from 20 to 10 g/l reduced growth and survival rate of in vitro shoots as well as that of transplants in the greenhouse. Only few shoots formed roots when they were grown on the medium containing 5 g/l of table sugar, and transplants failed to grow in the greenhouse. It found that the chlorophyll content of in vitro plantlets was lower than those of transplants grown in the glasshouse. However, the number of stomata of the in vitro plantlets was higher than that of transplants grown in the glasshouse. There was no anatomical abnormalities found on the cross section of leaves between in vitro plantlets and transplants grown in the greenhouse. The replacement of sucrose with table sugar may reduce the production cost of plantlets.Keywords: red ginger (Zingiber officinale Rocs.), reduction of sugar, survival rate, chlorophyll, stomata.

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 withÂ 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.

The protocol of micropropagation of Tetramolopium klossii (Moore) Mattfeld through adventitious shoot proliferation was established. This is the first report of T. klossii tissue culture. Seeds were surface-sterilized by dipping them in 10% of ethanol for 1 min followed by soaking in 1% of sodium hypochlorite for 10 min. The sterile seeds were germinated on MS medium solidified with 8 g/l of agar, supplemented with 20 g/l of sucrose. Two-month old seedlings formed some shoot clumps on MS solid medium without addition of any plant growth regulators. Small clumps containing 4-6 adventitious shoots were used for shoot proliferation on MS solid medium containing 0; 0.1; 0.5; 1.0 and 2.0 mg/L of BAP (benzylaminopurine) or kinetin. The results showed that medium MS without cytokinins (control treatment), and the addition of 0.1 or 0.5 mg/L of BAP was more effective for shoot proliferation compared to the medium with addition of BAP at higher concentration and the addition of kinetin. In further subcultures, multiple shoots grown on MS medium without cytokinins was Â more vigorous Â than that of shoots grown on other media, so that the shoots were ready for rooting. Medium containing 0.5 mg/L of BAP was the best for maintaining multiple shoot formation. Shoots formed roots on MS medium containing half strength of macro nutrients.

Tuber of purple yam (Dioscorea alata L.) has been used as an alternative food in some areas in Indonesia. The tuber contains high carbohydrate, has low glycemic index and is gluten free. Therefore, study on genetic improvement of this species needs to be carried out in order to increase its productivity and to find out new cultivars which can be cultivated in marginal lands. This research was aimed to investigate the effect of NaCl concentration on growth and proline content of purple yam grown in vitro. Shoot tips were cultured on MS (Murashige and Skoog) medium supplemented with NaCl at concentrations of 25; 50; 100; 200 and 250 mM. After six weeks in culture, height of shoots, number of nodes, number of leaves, as well as proline content were recorded. The results showed that shoots grown on MS medium supplemented with NaCl at 25 and 50 mM had better growth compared to control. The best medium for its growth was MS containing 50 mM of NaCl. An increase in NaCl level resulted in decrease of growth. The LD50 value was obtained at 183 mM of NaCl. The highest proline concentration was achieved by shoots grown on the medium supplemented with 100 mM of NaCl. This result indicated that purple yam was tolerant to the increase of NaCl concentration up to 100 mM on MS medium without addition of plant growth regulators.Â Keywords: purple yam, Discorea alata L., NaCl, in vitro growth, proline content.

ABSTRACTGenetic modification to increase productivity and other better growth characteristics of Kaliurang taro could be done by various methods; one of them is polyploid induction. Kaliurang taro has performed excellent traits, it is resistant to leaf blight disease and pests. Polyploid plants of Kaliurang taro are expected to have excellent char-acteristics and increased productivity. The objective to this study was to obtain an efficient method through in vitro induction of polyploidy using colchicine on Kaliurang taro. Aseptic plantlets of Kaliurang taro were soaked in colchicine solution at 0.05, 0.1 and 0.2% for 1, 2 and 3 days. Control was untreated plantlets. Each treatment consisted of 12 replicates. The colchicine-treated plantlets were then planted on MS medium containing 2 mg/L BAP, 1 mg/L thiamine and 2 mg/L adenine. Survival rate and vegetative growth of plantlets were observed every week for 8 weeks after planting. The results showed that increasing colchicine concentra-tion and the soaking period produced planlets with various survival rate. Flowcytometric analysis indicated that the treatment of soaking the plantlets in 0.05% colchicine for 1 day resulted in 14.3% of tetraploid plantlets. The most efficient of colchicine treatment was 0.2% for 3 days, resulting in 57.1% tetraploids, with the efficient value of 33.3%. There was chromosome multiplication from diploid to tetraploid which was confirmed through both flowcytometric analysis and chromosomes counting.Keywords: Taro (Colocasia esculenta L.), Kaliurang, in vitro, flowcytometer, chromosome multiplication, tetraploids
