Abstract

Vanda is one of the most cultivated orchid species.  In nature, Vanda is endangered because it was exploited in large quantities. Orchid genetic viability can be maintained by embryo culture. The study aimed to investigate the growth of Vanda helvola seeds during 12 weeks after cultured. Media Murashige and Skoog (MS) added with tomato juice 100 g/L was used as culture medium. The results showed that embryo could grow on MS medium on stadium 6th. Protocorm started to form at 9 weeks after cultured. At 12 weeks, percentage of protocorm formed reach almost 24.1%. Tomato juice improved the growth of protocorm of  V.helvola. Key words: Medium, protocorm, Vanda helvola

Abstract

Anthropogenic-origin forest disturbance has been known to increase the risk of invasion to native habitat. Invasive species caused problems for local ecosystems and their native species. The  research on the dynamics and autecology of invasive species Cyperus rotundus was conducted on anthropogenic disturbed Pohen mountain forest in Bali, Indonesia. Results showed significant changes in microclimatic variables from forest edge to interior. C. rotundus in Pohen mountain forest can be found in a road edge and forest exterior where sunlight is abundant and decrease in a more shady sites and absent under thick forest canopies CCA ordination analysis showed that C. rotundus in Pohen mountain forest tends to co-occur together with Imperata cylindrica and Bidens biternata. To be able to control potentially troublesome exotic invasive species, firstly we have to understand what factors limit their growth and development. Therefore this study is has important value because the data which from  result in studying invasive species autecology will act as baseline data that will be useful to generate management program including rehabilitation and restoration program. Key words: species dynamics, autecology, Cyperus rotundus, Pohen mountain forest, Bali

Abstract

This research was aimed to determine adaptability of  eight introduced  broccoli cultivars in the tropical climate, the effect of fertilizers, as well as determine the content of vitamin A, C and fiber owned by the cultivar. This research was using randomized complete block design (RCBD) with two factors. The first factorsare different broccoli cultivars namely Broccoli 'Lucky', Broccoli 'B-106', Broccoli 'B-116', Broccoli 'B-112', Broccoli 'Green 2109' F1, Broccoli 'Green calabrase' and Broccoli 'Green Magic 'and Broccoli' Mujur'as a control. The second factors fertilizer of ZA, manure and urea. This research was performed in Kopang, Central Lombok, West Nusa Tenggara, for seven months from December 2014 to Juni 2015.Analysis of the nutrient content was done at the Laboratory of Analytical Chemistry, University of Mataram, Lombok. Parameters observed in this research were plant height, number and weight of leaves, and quality of curd. Data were analyzed by analysis of variance (ANOVA) if significantly different then tested further by Duncan's Multiple Range Test (DMRT) at 5% level. The results showed all the cultivars able to adapt. Broccoli 'B-106' is a cultivar that has the quality and quantity of curd most excellent and able to adapt to high temperatures. ZA fertilizer application will produce curd weight and diameter greater than that ofmanure or urea. The research also showed that cultivar B-112 has the highest content of vitamin A, B-116 has the highest vitamin C and Green 2109F1 has the highest fibers. Key word: broccoli cultivars, adaptation, heat tolerance

Abstract

The role of insects in papaya plants is as pollinators, pests, parasites and predators of other insects. Referring to the role of insects, this research was conducted to determine the insects on an papaya plantations. Traping method using methyl eugenol and ripe papaya fruit as well as the manual method with insect net used in this research. Each method was repeated three times with an interval of sampling is one week. Insect netting done on the same day with traping method. Samples were preserved and then taken to the laboratory for identification. Environmental factors were measured are: temperature, humidity, latitude and altitude. Insects were identified by reference: Borror et al. (1992), CSIRO I & II (1991) and also Peggie and Amir (2006). Five species belonging to the genus Bactrocera found on methyl eugenol traps and five species belonging to the genus Drosophila was found in ripe papaya fruit traps as well as 16 other species found using insect netting around the papaya plant. In addition, there is also the genus Paracoccus on a papaya plant. Bactrocera papayae and genus Paracoccus is an insect pest on papaya plants.Keywords: diversity, insect, papaya plantation, Sanur

Abstract

Broccoli (Brassica oleracea L. var. italica Plenck.) is a vegetable crop belongs to Brassicaceae family.  Broccoli has high nutrition, high in fiber and contains isotiacyanate that has anticancer activity.  Broccoli market in Indonesia, particularly in modern supermarkets, increases 15-20% per year, however, productivity was still low, therefore effort to increase broccoli production in Indonesia need to be investigated. Field trial was conducted at Batur Village, Kintamani District, Bangli Regency, Bali, to find out cultivars that were adapted in tropical region. Introduced cultivars being trialed were ‘Alborada’,‘Belstar’, ‘Fiesta’, ‘Sarasota’, ‘Bay Meadows’, ‘Castle Dome’, ‘Liutenant’, ‘Iron Man’, ‘Marathon’, ‘Green Gold’, ‘Imperial’, ‘Green Magic’ and ‘Lucky’ as control.  Variable observed were vegetative growth, curding period, and productivity of each cultivar.  This study employed Randomized Completely Block Design with 3 replicates (plots) and 8 plants each plot.  Data were analyzed using ANOVA (Analysis of variance) on Costat program, followed by Duncan’s Multiple Range Test (DMRT) on 1% level.  Results show that each cultivar varied in adaptability in tropical region. ‘Castle Dome’ has the highest productivity, while ‘Fiesta’ was the lowest. Keywords: Brassica, field trial, cultivar

Abstract

This research was aimed to find out the genetic structures of three generations of Balinese population, in order to determine the best loci used for paternity testing among this population, and observed the mutation rate of these loci. The DNA samples were taken from the epithelium cell of 25 families which were collected from the children, father, mother, grandfather and grandmother of the children, from both mother and father sides (family with three generations). The DNA was extracted in Phenol-Chloroform method with modifications. DNA amplification was conducted in PCR method using pairs of primer 5, namely: FGA, D18S51, D2S1338, TPOX, and D16S539, and its products were electrophoresed and visualized in 10% of PAGE, stained in silver nitrate. The genetic structures of the three family generations showed 30 variants with different frequencies in each locus. The highest heterozygosity value was detected in FGA (8 alleles), then followed by D18S51 (7 alleles), TPOX (6 alleles), D16S539 (5 alleles), and the lowest was in D2S1338 (4 alleles). The highest value of heterozigosity and Power of Discrimination were found in FGA, followed by TPOX, D18S51, D2S1338, and the lowest was in D16S539. Therefore, it can be concluded that out of five loci tested, 4 of them can be recommended to be used for paternity testing of Balinese population, except D16S539. Keywords: Paternity Testing, DNA Microsatellite, three generations, heterozygosity, Power of Discrimination

Abstract

Bali is a small beautiful tropical island of Indonesia archipelago, lies between the continent of Asia and Australia, as well as the Indian and Pacific Ocean. As a tropical archipelago, many kinds of biodiversity can be found. The island of Bali in particular, there are typical animal diversity that could not be investigated beyond such island, such as, Bali cattle, Bali dog, Bali starling and others. As time goes on, the existance of such biodiversity decreases in both body weight and population number. Both global warming/climate change and land use change are the main factors affecting such phenomenon. This study has been conducted by employing field observation as well as literature study. It was found that, the quality of purebred Bali cattle species decreases genetically that could be notified of smaller bodysize for both male and female. Land use change of agriculture activity to the hotels, house of living, roads and other infrastructures are the main factors for Bali cattle existence. For typical famous bird of Balistarling, the problem is because of deforestation which cause natural habitat loss, due to land use change for agricultural activity and house building by local people. In case of Bali dog, the mad dog of rabies is just introduce and spreading over Bali island, whichis formerly the island of Bali has been recognised as free zone area of the rabies. As consequence, suffering dogs must be eliminated by  mass killing cause decrease total number of such poor dog. Overall, it could be concluded that environmental degradations of land use change, deforestation and desease are the main causes of biodiversity decreasing number of the Bali cattle, Bali white starling and Bali dog respectively, beside global warming/climate change natural disaster. Key words: Environment, Bali cattle, Bali starling, Bali dog, Bali island.
