Abstract

ABSTRACTStevia rebaudiana is plant species producing natural sweetener with has low calories. The species propagation could be done by tissue culture tecnique to obtain propagules with high quality and sustainability. Modification of media composition and in vitro environment will increase growth and vigority of explants so that they have high survival rate during acclimatization. The aim of this research was to increase growth of stevia shoot culture by increasing the level of vitamins in combination with different type of test tube covers. Stevia shoot tips were cultured on MS medium containing normal concentration of its vitamins (control treatment; Myo-inositol 100 mg/l; Nicotinic acid 0.5 mg/l; Pyridoxine-HCl 0.5 mg/l; Thiamine-HCl 0.5 mg/l and Glycine 2 mg/l), twice and 4 folds of vitamin levels, they were grown on culture tubes with Al-foil and ventilated-plastic with filter (2 cm diameter and pore size at 0,22 micron). Height of shoots, number of nodes, number of leaves, number of roots were observed every week till 8 weeks of culture. Biomass (fresh and dry weights) and chlorophyll level and acclimatization were done 8 weeks of culture. The results showed that type of culture tube covers affected significantly to all growth parameters, biomass as well as level of chlorophyll, meanwhile level of vitamins only affected number of nodes, shoots and roots. Interaction between vitamin level and covers types only occured for height of shoots and number of roots. Plantlets grown on medium containing 4 fold of vitamin level (Myo-inositol 400 mg/l; Nicotinic acid 2 mg/l; Pyridoxine-HCl 2 mg/l; Thiamine-HCl 2 mg/l and Glycine 8 mg/l) with ventilated-plastic cover had larger leaves compared to other treatments. All plantlets survived in a greenhouse.Keywords: Stevia rebaudiana, in vitro growth, increase in vitamin concentration.

Abstract

ABSTRACTGenetic improvement of taro (Colocasia esculenta L.) is one of important research program to increase productivity and give better cultivation on the marginal land. Induction of polyploid plants is a method useful to increase genetic diversity. The aim of this research was to induce polyploid taro by oryzalin treatment. Polyploidy was induced from in vitro diploid taro ‘bentul’ using oryzalin at 7.5; 15; 30; 60 and 75 ?M soaked for 3 days. Regenerated shoots were grown on MS medium containing 2 mg/l BAP, 1 mg/l thiamine and 2 mg/l adenine. Shoot growth was recorded four weeks (subculture-0), eight weeks (subculture-1) and twelve weeks (subculture-2) after treatments. The results showed that survival rate of treated shoots was 100%. Higher oryzalin concentration reduced the proliferation of shoots, petiole length, numbers of leaves as well as the numbers of roots. Ploidy levels analysis determined by flowcytometer for 122 plantlets were investigated. The results indicated that control shoots were diploid. All treated shoots were polyploids. Oryzalin at 60 ?M gave 50% of tetraploid planlets, 30 ?M of oryzalin gave 5.71% hexaploids, 60 ?M of oryzalin gave 9.09% octaploids. All acclimatized plantlets gave 100% survival rate.Keywords : Colocasia esculenta L., taro, in vitro induced polyploidy, oryzalin

Abstract

ABSTRACTSomatic cell manipulation of Artemisia annua L. was conducted by induction of polyploid plants with Colchicine and Oryzalin in order to increase level of artemisinin. Polyploid plantlets were multiplied on MS medium without plant growth regulators. After acclimation processes, plants were grown in the field for agronomic performance observation. Survival rate of plantlets was recorded. Agronomic performance of plants was observed by recording height of plants, number of branches, leaf biomass, stomatal characteristics, and artemisinin content. The results showed that survival rate of the plantlets from Colchicine and Oryzalin treatments were ranging from 13.40 to 33.33% and 11.11 to 41.67%, respectively. Growth rates of plant height and plant branching were not significantly different between diploid and tetraploid plant both from Colchicine and Oryzalin treatments, except to triploid plants from Colchicine treatment. Averages of plant height from Colchicine and Oryzalin treatments were ranging from 10.0 to 220.0 cm and from 35.0 to 186.0 cm, respectively. The averages number of branches per plant of polyploid plants from Colchicine and Oryzalin treatments were ranging from 3 to 66 and from 11 to 63, respectively. Averages of dry leaves biomass between diploid and tetraploid plant from Colchicine and Oryzalin treatments were also not significantly different. They were ranging from 12 to 64 g/plant and from 11 to 62 g/plant, respectively. However, tetraploid clones have bigger size of stomata and produced more artemisinin than the diploids.Keywords: Artemisia annua L, Colchicine, Oryzalin, Polyploids, Acclimation, Agronomic performance

Abstract

ABSTRACTTaro (Colocasia esculenta (L.) Schot.) has been cultivated for a long time in Indonesia. Taro tuber can be used as alternative food for rice substitute to support food diversification program. Taro cv. Bentul is preferable to farmers because it has few buds that are easy to maintain and adaptable in both lowlands and highlands. Its tuber has a delicious taste and a soft texture. Somatic cell manipulation of Indonesian taro through biotechnology may contribute to increase its productivity. One of in vitro technique for somatic cell manipulation is polyploidy. Oryzalin has been able to obtain taro cv. Bentul tetraploid. A total of 17 tetraploid clones were used in this study for clustering. Those clones were obtained from previous research and have stable ploidy level. The objective of this study was to determine cluster Bentul tetraploid of shoot culture using Ward method based on their in vitro growth as an initial selection before further selection in the field. Shoot tips of tetraploid were cultured on MS medium containing 2 mg/l BAP, 1 mg/l thiamine and 2 mg/l adenine for 6 weeks. The observed growth variables were number of shoots, length of petiole, number of leaves and roots. The clusterring was done using Ward and Euclidean Distance method followed by Analysis of Varians and Duncan Multiple Range Tests (DMRT). Out of 17 clones observed resulted in 3 clusters. Cluster 1 consisted of 2 clones, cluster 2 consisted of 9 clones, and cluster 3 consisted of 6 clones respectively. The best cluster was cluster 3 which was significantly different on the average number of shoots and leaves. Cluster 3 was dominated by clones derived from oryzalin at 75 ?M.Keywords: taro (Colocasia esculenta (L.) Schot.), tetraploid, in vitro growth, cluster analysis, Ward

Abstract

Taraxacum officinale Weber ex F. H. Wigg. is a herbaceous medicinal plant species belonging family Asteraceasewhich has apomictic and poliploid characteristics. Multiplication of shoots using tissue culture was used to obtaindefine high quality seedlings, uniform, stable or free of diseases. However, changes in chromosome number canoccur in regenerated plants. The research aim was to determine the chromosome number of T. officinale plants regeneratedfrom culture in vitro using explants of roots, petioles and leaf blades. Therefore, selection of regenerantscan be done in order to find out transplants which have high yield of secondary metabolites. Analysis of chromosomenumber from root tips samples was conducted using 24 plantlets regenerated from root, 27 plantlets regeneratedfrom leaf blade, 21 plants regenerated from petiole and 102 roots of grown seeds using orcein squash method.The results showed that germinating seeds (control) and regenerated plants had variation in chromosome number.The range of chromosome numbers from regenerated plants were 2n=8-39, and cells with diploid number (2n = 2x= 16) was as most observed. The range numbers in germinated seeds were 2n=10-38, and cells with triploid number(2n = 3x = 24) was as most observed. This results proved that variation in numbers of chromosome was caused byapomixis and poliploid characteristics of the parent plant regenerated to their regenerants.Keywords : Taraxacum officinale.

Abstract

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

Micropropagation of Beneng Taro (Xanthosoma undipes K. Koch) with Benzyl Amino Purine, Thiamine, and Adenine TreatmentABSTRACTConventional production of Beneng taro seeds (Xanthosoma undipes K. Koch) is constrained by the limited number of tubers, thus an alternative solution is needed such as in vitro propagation. This study was aimed to obtain a micropropagation technique of Beneng taro on MS media with BAP, thiamine, and adenine treatment, and to determine its growth at the acclimatization stage. This research consisted of shoot multiplication and acclimatization. Shoot propagation was carried out on MS media with 8 treatments, namely ½MS and MS without addition of growth promoting substance, and MS with 1, 2 and 3 mg×L-1 BAP, with or without addition of 1 mg×L-1 thiamine and 2 mg×L-1 adenine. Each treatment was replicated four times, each consisting of four shoots. Growth observation was made from 1st to 5th week on petiole length, and number of shoots, leaves and roots. Acclimatization was carried out on soil media, compost, and husks in a ratio of 1: 1: 1. The results showed that the best media for shoot multiplication was MS + 1 mg×L-1 BAP + 1 mg×L-1 thiamine + 2 mg×L-1 adenine with an average of 3.5 shoots, while the best medium for the petiole length was ½MS with an average value of 6.97 cm. The results of acclimatization showed that 100% planlets survived, and plantlets grown on MS media + 3 mg×L-1 BAP had the highest number of shoots with an average of 4.2.Keywords: adenine, Beneng taro, benzil amino purine (BAP), micropropagation, thiamineABSTRAKPenyediaan bibit talas Beneng (Xanthosoma undipes K.
