Abstract

White rust caused by fungal pathogen Puccinia horiana P. Henn. is one devastated disease that could make significant economic loss in chrysanthemum production. The study of effects of varieties, cutting health and fungicide application on chrysanthemum white rust was established. The treatments were arranged in split-split plot completely randomized design with three replications. Three chrysanthemum varieties i.e. cv. Puma White, Reagent Purple and Town Talk served as main plot. Seedlings with 20 % intensity of white rust infection and symptomless functioned as sub plot, while fungicide application on the transplanted cutting (no fungicide) and dithiocarbamate (AntracolR 75 WP, 2 g L-1) application served as sub-sub plot. Result showed genetic background of the cultivars significantly determined the degree of infection of white rust. Reagent Purple exhibited least disease intensities. Fungicide application was less effective in controlling white rust development, yet gave significant impact on the plant height and number of leaves of chrysanthemum plants. Cuttings selection based on the visual observation on the presence or absence of white rust pustules symptom did not gave significant differences on the further development of the disease. The symptomless cuttings were also infected with this fungal disease after the cuttings were planted under plastic house.

Abstract

Dimorphorchis lowii is a rare epiphytic orchid endemic to Borneo and very popular due to its ornamental value. For the purpose of mass propagation, procedures for in vitro propagation through callus were developed. The objectives of this study were to determine the effects of plant growth regulators (PGRs) on callus induction from leaf tip explant and the effects of complex additives on PLBs formation and shoot development. The best combination of PGR was 3.0 mg L-1 Thidiazuron (TDZ) with 0.046 mg L-1 NAA supplemented in half-strength medium (½ MS) (Murashige & Skoog, 1962). The percentage of survival and callus formation obtained were 96.0 % ± 19.8 and 52.0 % ± 16.5 respectively. Maximum shoot proliferation from PLBs was observed in Knudson C (KC) medium enriched with 15 % (v/v) coconut water. In this treatment, 10.2 ± 6.2 shoots were produced from one callus explant. Shoots were rooted on KC medium containing 15 % (v/v) coconut water and transferred in a medium mixture containing sphagnum moss, charcoal, brick and coco peat with the ratio of 1:1:1:1. After 2 months being acclimatized in the glasshouse, 78 % of plantlets survived. Histology observations showed that embryogenic callus derived from leaf tip explants might originate from epidermis and mesophyll cells and was capable of developing into complete plantlets.

Abstract

Sesame is an important commodity in supporting various industries such as low saturated fat oil producing and are often able to adapt under stressed grown conditions. Breeding sesame is undertaken to increase production and is possible by radiation induced polygenic characteristic changes with a gamma rays source. The study aims to identify the effectiveness of genetic variability, standardized multiple linear regression, and principal component analysis to determine some important sesame yield components for indirect selection. Eighteen sesame mutant lines (black and white types) were studied for eleven quantitative traits. Two sesame types were irradiated with eight doses (100-800 Gy) of gamma rays individually. Variability studies on seed yield and yield components are important raw material of high productivity for all studied traits. Standardized multiple linear regression analysis is the most effective way to provide information of relationship between seed yield and yield components in sesame mutant lines for indirect selection.

Abstract

Most of Indonesian red rice is not grown in dry land. New varieties could be breeded through mutation breeding. This research objective was to evaluate the selection strategy of drought tolerant on red rice. The study was conducted on ultisol soil in Bangka Belitung Province, Indonesia, in February 2012-February 2015. It consisted of three activities, selection M5, evaluation of selected M5 and evaluation of drought critical period on selected M6. Mutant of M5 was selected and evaluated with polyethylene glycol (PEG) -0.5 MPa and less of soil moisture. Selected M6 was evaluated to observe a critical period of drought stress. Evaluation with PEG produces five superior mutants that more vigor than the elders. Selection on low humidity shows that M5-GR150-1-9 produces higher filled grain and weight filled grain than other mutants and elders. The selected red rice line M5-GR150-1-9-13, has a better tolerance towards drought than its control. It could be obtained such mutant lines which have a high yield, early maturing and drought tolerant from the result of six generations gamma irradiation mutant selection.

Abstract

Morphological and genetic characterization of tamarind are useful and important for breeding, commercialization and gene bank management. The cultivars characterized in this study were Intapalum, Sritong, Prakaitong, Khantee and Srichompoo. The comparison of five sweet tamarind cultivars were carried out using ANOVA and DMRT with 0.05 of significant levels. The relationship between morphological characteristics was calculated by the Pearson’s correlation coefficient. Phylogenetic analysis used NTSYSpc ver. 2.1 to generate a dendrogram of fruit characters. The quantitative characters (pod weight, pod diameter, and pod length) were significantly different. The biggest fruit was Sritong and the smallest was Khantee. Significant differences were shown on two qualitative characters such as pod shape and flesh color, while there were no significant difference on the seed shape, seed color and skin color. There were positive correlations among all quantitative pod characters of the samples. Pod weight was significantly correlated with pod diameter, however pod length and pod diameter were not significantly correlated. The similarity level from five sweet tamarind cultivars was 44-100 %.

Abstract

An Agri-Environmental Scheme (AES) was designed to enhance flower availability in crops using local wild plants. The goals of this research were to determine the impact of four wild plants on three cash corps, focusing on the diversity and abundance of insect pollinators, and to test the efficacy of this scheme using farmland on the northern slope of Mount Slamet. This research was done using a split block design, with the three cash crops as blocks (strawberry [Fragaria x ananassa Duchesne], chili pepper [Capsicum spp.], and tomatoes [Solanum lycopersicum L.]) and four wild plant species as treatments (Cleome rutidosperma, Borreria laevicaulis, Euphorbia heterophylla, and Tridax procumbens) at different precentages (0, 5, 10, and 15 %) of cash crop plant density. The results show that growing wild plants with cash crops enhanced the abundance and diversity of insect pollinators. Moreover, the addition of wild plant species to the crops at four densities had significantly different effects on insect pollinators in terms of abundance and diversity. The combination of 15 % C. rutidospermae and tomatoes had the largest population of insect pollinators. From the experiments it concluded that an AES could be implemented in farmland on the northern slope of Mount Slamet.

Abstract

Conserving plant diversity and retaining terrestrial carbon stocks are targets for environmental policy and appear to be generally compatible. However, detailed information on the way both respond to agroforestry management is lacking. Rubber and fruit tree agroforestry systems combine planted trees and trees that are tolerated or actively managed that derived from natural vegetation. The research aimed to evaluate plant species diversity, vegetation structure, and C stock in rubber agroforestry system (AF) and secondary forest grown in silty clay and sandy soils in Pulang Pisau Regency, Central Kalimantan province. A number of multistrata agroforestry systems was compared to the secondary (natural) forests (SNF) of the area; these included Fruit-Based Rubber Agroforestry (AFB) of about 100 years of age, Old Rubber Agroforestry (ARO) and Young Rubber Agroforestry (ARY). The highest C stock was found in AFB (415 Mg ha-1), while the average C stocks of other AF and SNF were 217 Mg ha-1. A plant diversity index (H’) was only weakly correlated to aboveground C stocks. Including the farmer-managed agroforests in schemes to reduce emissions from deforestation and forest degradation is relevant, as their carbon stocks match or exceed those of remaining forests in the area.

Abstract

Dickeya dadantii is one of newly found bacteria causing soft rot on orchids in Indonesia. Infected plants showed severe rot rapidly only in few days. An effort to control the bacteria was conducted by utilizing selected quorum quenching (QQ) inducer bacteria which produce AHL-lactonase by aiiA gene. The aims of this research were to screen and identify of quorum quenching bacteria, and also assayed their biocontrol potential ability against D. dadantii in laboratory. The screening of QQ bacteria was achieved using the anti-QS test, anti-microbial activity, and detection of aiiA gene using specific primer. The determination of the ability against D. dadantii was done using the soft rot assay on potato and orchid. Among thirty one bacteria isolates screened, four isolates (in succession namely B37, BT2, GG3, and GG6) were selected to control D. dadantii. All of these bacteria showed QQ ability to suppress the virulence of D. dadantii infection on orchids, significantly. Based on nucleotide sequences of 16S ribosomal RNA, those of bacteria isolates had the highest identity with Brevibacillus brevis, Bacillus cereus ATCC14579, Bacillus cereus ATCC14579 and Bacillus thuringiensis ATCC 10792. Brevibacillus brevis was reported for the first time as QQ bacteria in this study.

Abstract

Curvularia lunata was found to cause a serious rice brown leaf spot in Cambodia. This is the first report of brown leaf spot on rice in Cambodia. All isolates were tested for pathogenicity. Dual culture antagonistic tests showed that Chaetomium cupreum inhibited sporulation of C. lunata when compared to the control. In a pot experiment, C.  cupreum significantly reduced the incidence of brown leaf spot caused by C. lunata. After application of a spore suspension of C. cupreum, Chaetomium-biofungicide and chemical fungicide (tebuconazole) to rice seedlings inoculated with C. lunata, the disease was reduced by 68.79 %, 75.80 % and 72.41 %, respectively. In a field trial, the chemical method gave the best results in all plant parameters, followed by the good agricultural practice (GAP) and organic methods. The chemical method gave the highest panicle/plant, panicle length, panicle weight, grain weight/plant which were different from the GAP and organic methods. The chemical method also gave the best results in filled grain panicle-1, unfilled grain panicle-1, grain weight plot-1, dry hay weight plot-1, biomass weight plot-1 and harvest index, and was significantly better than the GAP and organic methods.
