Abstract

Central Bangka Regency is one of central orange production in Bangka Belitung Islands Province. One of the important pests of sweet orange plants is fruit flies (Diptera: Tephritidae). This research aimed to study the diversity of fruit flies (Diptera: Tephritidae) on sweet orange plantations in Central Bangka Regency, Bangka Belitung Islands Province. The fruit flies were collected using Lynfield traps which installed in three villages producing sweet oranges in Central Bangka Regency. The types of attractants used to trap male fruit flies are methyl eugenol and cue lure. The fruit flies collected during the study were 4795 individuals, 3 genera, and 14 species. Fruit flies collected from the methyl eugenol were different compared to those collected using lure attractant trap. Most species (13 species) of fruit fly were found in Terentang village, and the rest was same (9 species). Bactrocera carambolae and B. dorsalis were the dominant fruit fly species in the three research locations.

Abstract

Rhizosphere and endophytic fungi are functional types of microbes capable of producing secondary metabolites that can affect plant growth directly or indirectly. This study aims to isolate and test the rhizosphere and endophytic fungi' ability from Moringa (Moringa oleifera L.) against rice seeds' viability and vigor. Fungus exploration was carried out on soil samples in the rhizosphere and stem and leaf tissue of healthy Moringa plants. Isolation of fungi from the rhizosphere was carried out using 10-2 and 10-3 dilution techniques, while the isolation of endophytic fungi was carried out on the leaf and stem tissue of Moringa, then cultured on potato dextrose agar (PDA) medium. The pathogenicity test of fungi and its effect on in-vitro rice seed germination using the blotter test method, namely growing 25 rice seeds on seven-day old fungal isolates. Nineteen fungal isolates were isolated and collected from the parts of the Moringa plant. Pathogenicity observations showed that there were five fungal isolates as potential pathogens, namely isolates RF2, RF5, RF6, RF8, and EDF6. A total of four fungal isolates tested consistently showed a positive effect on seed viability and vigor with a value of ≥90%, namely isolates RF4, EDF1, EDF2, and EDFbt3.

Abstract

Bamboo are known having a high adaptive ability to tolerate environmental changes or stresses. Endogenous microorganisms in several parts of bamboo have been reported used as organic fertilizer and biocompost. However, bacterial potential as auxin (IAA) producer has not been widely report, especially for Torajas’ local bamboo. In this study, rhizosphere and endophytic bacteria were isolated from six different bamboo. Bamboo samples were obtained from the bamboo forest station area of North Toraja. Rhizosphere bacterial isolates were obtained from the area around the roots of bamboo plants, while endophytic bacterial isolates were obtained from roots and shoots bamboo tissue. Six rhizosphere isolates and 12 endophytic isolates were obtaind. All isolates were indentified for morphological, physiological, biochemical tests and IAA’s activities. There are 12 IAA-producing isolates, which where dominated by endophytic bacterial isolates. Based on 16S molecular identification, it was found that K12 isolates were similar to Bacillus cereus, with an IAA concentration value was 1.301 mg L-1. While K14 isolated has similiarities with Stenotrophomonas maltophilia with the abiliy to produce IAA was 2.737 mg L-1. The reconstruction of the phylogeny tree showed that K12 isolate had similiarity with Bacillus wedimannii, and K14 isolate was related to Stenotrophomonas sp.

Abstract

Genetic enhancement in vegetatively propagated crops can be done through mutation induction. Colchicine-induced mutation is one of the methods that can be employed to increase plant genetic diversity. This study aimed to determine the effect of colchicine on the performance and genetic parameters of MV3 generation of Plectranthus amboinicus (L.). This study was conducted at the Laboratory of Agricultural Seed Management, Plantation Research and Development Center, from June 2018 to June 2019. Nodes and shoots were used as explants. Mutation induction was performed using colchicine at concentrations of 0%, 0.02%, 0.04%, and 0.06%. Explant regeneration and subculture were done on MS0 medium. The number of plantlets yielded were 59 (0% concentration of colchicine), 60 (0.02%), 81 (0.04%), and 80 plantlets (0.06%), respectively. Results indicated that colchicine-induced mutation in an in vitro culture was able to generate high genetic diversity in both quantitative and qualitative characters of the plantlets. At the concentration of 0.04%, colchicine produced the highest frequency of putative mutants (28.4%). Genetic parameters in MV3 generation of P. amboinicus plantlets showed that five quantitative characters, i.e. plantlet height, number of leaves, number of shoots, leaf length, and number of roots had high heritability values at a concentration around the LC50 value (0.0275%).

Abstract

Patchouli is a plant that produces essential oils that cannot be substituted with other essential oils. The genetic diversity of patchouli is low, because in Indonesia there are only five superior clones, and this is caused a limitation for cultivation. Therefore it is necessary to produce new superior clones filled by national standards. This study tested nine patchouli superior genotypes resulting from mutations. The main objective of this research were to obtain the results stability, wide variability, to determine the correlation of each parameter and class closeness among ten patchouli genotypes. The study used nine plant clones of patchouli from the collection and one patchouli variety released in Indonesia as a comparison, namely Lhoksemauwe. The treatments were arranged in a completely randomized block design with three replications. Based on the results of the study, there was no significant difference in almost all observed parameters except for the stem diameter parameter. The genotype used has shown the stability of the results at the Rajabasa location in South Lampung. The variability in almost all parameters showed broad criteria, except for the parameters of cell turgidity and oil yield. Significant positive correlations occurred between several observed parameters. There are four classes formed and three of it have more than 90% closeness.

Abstract

Black rice still contains epidermis which is composed of several layers, including pericarp, lemma, aleuron and testa so that cooking takes a long time. To speed up the cooking time on rice can be modified by parboiling process so that it changes the character of gelatinization. The research aims to find out the effect of the concentration of sodium citrate solution and immersion time on the process of black rice parboiled Sirampog varieties on its gelatinization properties. Soaking in sodium citrate solution at a certain time is expected to accelerate the cooking time of black rice. The research using Completely Randomized Factorial design consisting of concentration of sodium citrate solution (0, 3, 5 and 7%) and immersion time (20, 30 and 40 minutes). The variables observed were gelatinization properties including gelatinization temperature, peak viscosity, final viscosity, breakdown viscosity, trough viscosity and setback viscosity. The results showed that the setback viscosity and peak viscosity of Sirampog rice were affected by the concentration of sodium citrate. The sodium citrate solution of 5% as a marinade produces Sirampog varieties of parboiled rice with high trough viscosity and lowest setback viscosity, which means it is easier to cook and more resistant to retrogradation during cooling.
