Abstract

Bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious diseases in rice production. Breeding varieties specifically for their resistance to BLB disease is therefore an efficient and cost-effective strategy. However, the resistance gene for BLB can be race and non-race specific, meaning it is often overcome by the pathogen. The identification of new sources of resistance genes for Xoo is crucial in rice breeding programmes. In this study, six rice varieties were assessed using six Xoo isolates in multiple screening conditions. The GGE biplot analysis considers both genotype (G) and genotype environment (GE) interaction effects and demonstrates GE interaction. The first two principal components (PCs) accounted for 95.46% of the total GE variation in the data. Based on lesion length and stability performance, Phaladum was the most ideal genotype against all Xoo isolates in the four screening conditions. The results relayed that Phaladum indigenous rice varieties could be considered as new sources of bacterial leaf blight resistance in Thailand. In the future, the BLB resistance gene in this variety will be identified in regard to mode of inheritance and used as parental line in rice breeding programmes for resistance to BLB.

Abstract

The objective of this research was to determine the diversity and relationship of sapodilla accession derived from districts in DIY based on DNA profiles. From the screening of 20 total primers, five primers (OPA 20, OPB 5, OPB 6, OPB 8, and OPC 19) producing polymorphic bands in RAPD analysis were selected. Different-shaped samples of sapodilla randomly collected from Bantul, Gunungkidul, Kulonprogo, Sleman and Yogyakarta city were used in this research. The analysis of molecular data was performed by using NTSys pc-2.02 and GenAlex 6.1 program. The clustering indicated that the accessions tend to group by their locations. However, there was no corelation between DNA marker and the fruit shape. The first group comprised samples from Yogyakarta city (Keraton Yogyakarta), Bantul and Kulonprogo while the second group consisted of samples from Sleman and Gunungkidul with genetic similarity of 53% and 37% respectively. The genetic diversity was high (PLP = 98.85% of 87 loci and H=0.280±0.14) comprising the genetic diversity within population (53%) which was greater than genetic diversity between populations (47%). Having the highest genetic diversity, Gunungkidul should be potential for conservation and selection of sapodilla in DIY.

Abstract

This study explores ways to effectively and efficiently finance Reducing Emissions from Deforestation and Forest Degradation (REDD+) activities to enhance climate change adaptation and biodiversity conservation by drawing on lessons from the Global Environment Facility (GEF). The study analyzed trends in the focal areas of GEF forest-related projects, the executing and implementing agencies involved in GEF forest-related multi-focal area projects, and the cofundraisers’ trends in GEF forest-related multi-focal area projects. The analysis of GEF forest-related projects identified ways to finance REDD+ mobilization and distribution to enhance its multiple benefits. The key agencies that support REDD+ activities and enhance these co-benefits are the United Nations Development Program (UNDP), the Food and Agricultural Organization (FAO), the World Bank, the United Nations Environment Program (UNEP), and the national governments of developing countries. GEF and the co-fundraisers—multilateral aid agencies, such as UNDP, the World Bank, FAO, the Asian Development Bank, and UNEP, bilateral aid agencies, such as Germany, the United States and the European Union, the private sector and nongovernmental organizations—all work to enhance REDD+ co-benefits. Because private contributions to the GEF are limited, it is important to design a scheme to mobilize more private financing for REDD+.

Abstract

Tea is a commodity that has a significant contribution to Indonesia’s foreign exchange, especially from non-oil and gas sectors. Fertilization is one of the important factors to produce high productivity and keep the plant healthy. The healthy plants are simply indicated by the ratio of pecco and banji more than 2.33. This research aimed to test the effect of Mineral-Based Compound Fertilizer (CFC) on a plant health and tea plant productivity. The research was carried out in April – October 2014 at the Gambung Experimental Station, Block B6, Research Institute for Tea and Chincona by using CFC with a composition of 80% Mineral Compound Fertilizer, 10% urea, and 10% KCl. The experiments used a Randomize Blocked Design with four replications and six treatments; i.e. 120% CFC tekMIRA; 100% CFC tekMIRA; 80% CFC tekMIRA; 60% CFC tekMIRA; NPK (25:7:12:3) as control compound fertilizer; and single standard fertilizer. The result showed that all of the treatments did not increase the plant health. However, the application of CFC produced a higher tea plant productivity compared to NPK (25:7:12:3) as control compound fertilizer and single standard fertilizer. Based on regression equation, the dose of CFC that produced the optimal tea productivity was 93.92%.

Abstract

The study aimed to determine the response of two local rice cultivars subjected to different doses of nitrogen (N) fertilizer in two paddy fields, namely Petung and Gunung Makmur in Penajam Paser Utara, East Kalimantan. The research was arranged in Nested Design with five doses of N fertilizers, two cultivars, and two locations as treatments. The doses of N fertilizers were 0, 25, 50, 75 and 100 kg N.ha-1 nested in two cultivars (Nanung and Pance Kuning) and two locations (Petung and Gunung Makmur). Each treatment was conducted in three replicates. The result showed that the Pance Kuning cultivar was superior than Nanung in Petung location in terms of the number of tillers per hill, number of productive tillers per hill, percentage of filled grain per panicle, weight of 1000 grains and potential yield. A different effect of N fertilizer was observed on the number of tillers per hill, percentage of filled grain per panicle and weight of 1000 grains. Nanung and Pance Kuning showed positive responses to the application of 75 kg N.ha-1 in Petung for the parameters of tiller number and weight of 1000 grains.

Abstract

The anthracnose pathogen was isolated from coffee leave and bean symptoms. Morphological and molecular phylogenetic data confirmed the species as Colletotrichum gloeosporioides. The pathogenicity of the isolate was also confirmed by detached leaf method which inoculated the virulent isolate into coffee leaves. The crude extracts with hexane, ethyl acetate and methanol solvents from Chaetomium cupreum CC3003 resulted significantly inhibited C. gloeosporioides that the ED50 values of 13, 11 and 28 ppm, respectively. The bioactive substances of C. cupreum CC3003 expressed antifungal activity against C. gloeosporioides as can be seen in the abnormal appearance of spores. A powder bio-formulation of C. cupreum significantly resulted to reduce anthracnose disease of 54.77 %. The application of nano-rotiorinol, nano-trichotoxin and a spore suspension of C. cupreum reduced anthracnose incidence of 46.23, 42.71 and 18.59 %, respectively while the inoculated control had high anthracnose disease. The application of bio-formulation of C. cupreum in powder form, nano-rotiorinol, and nano-trichotoxin to reduce coffee anthracnose was reported for the first time in Lao PDR.

Abstract

A study was made to determine total number of bacteria living in the rhizosphere of three common plants at BRIS soil namely Acacia mangium, Melaleuca cajuputi Powell and Eleusine indica that grow on field. Soil samples were collected from each plant’s rhizosphere at three different locations of UniSZA Apiary, AGROPOLIS Research Farm and FBIM Teaching Farm at UniSZA, Besut Campus on May and November 2015. Enumeration of total bacteria by standard plate counts found that Acacia’s rhizosphere at AGROPOLIS Research Farm showed the highest CFU g-1 in November 2015 for aerobic (6.14 x 106) and anaerobic (3.97 x 106) bacteria. Acacia’s rhizosphere from UniSZA Apiary showed the highest CFU g-1 value in November 2015 for nitrogen fixing bacteria (aerobic; 1.87 x 106, anaerobic; 1.5 x 106) and phosphate solubilization bacteria (aerobic; 1.4 x 106, anaerobic; 1.41 x 106). The rainy season on November gave a higher bacterial CFU g-1 number (20-44 %) compared to the dry season on May for all different plants and locations. The finding showed that although BRIS soil is the problematic and unfertile soil, it has a large number of bacterial colony that might be beneficial to be exploited for enhancing plant growth and soil fertility.

Abstract

Clinacanthus nutans is an essential medicinal plant that had been used in various local remedies to treat many illnesses. A study had been conducted to determine the phenolic, flavonoid, antioxidant activities and phytochemical compounds of C. nutans in different locations. C. nutans were harvested from eight locations and the leaves were extracted with 80 % methanol by maceration process. Then, the phytochemical screening using Gas Chromatography-Mass Spectrometry (GC-MS), 2,2 diphenyl-2-picrylhydrazyl hydrate (DPPH) assay method, total phenolic content by Folin Ciocalteu’s assay method and total flavonoid content by aluminium chloride (AlCl3) were carried out. The C. nutans extracts showed higher antioxidant activities than phenolic and flavonoid content. The neutral pH sandy clay soil from location KKK (Kuala Ketil, Kedah, Malaysia) had higher antioxidant activities (58.0 %), phenolic (44.1 mg GA.100 g-1) and flavonoid content (30.8 mg QE.100 g-1) compared to other locations. The GC-MS analysis showed the presence of phytochemicals constituents of 20 compounds. The results revealed that environmental factors (light intensity, temperature and soil characteristics) of eight locations were responsible for variations of phenolic, flavonoids, antioxidants and GC-MS analysis in C. nutans. The findings of this study will provide baseline data for future breeding programs for commercial cultivation.

Abstract

Priority products in homegarden agroforestry systems are still dominated by wood. Understorey is an important component of the homegarden community, but not a priority in its management because there is not much information about its benefits. Undestorey has several benefits such as food sources, food crops and medicinal materials. Research aimed to know the diversities of understorey species, the dominant of understorey species and the content of compounds in dominant understorey in the homegarden agroforestry system in Menoreh hill, Kulon Progo Regency. The study sites were categorized into 3 zones based on elevation, i.e. zone 1 (< 300 m above sea level (asl)), zone 2 (301-600 m asl) and zone 3 (> 600 m asl). This research method used inventory and identification of understorey species, and identification the content of dominant understorey compound by TLC method. The results showed that there were 41 species of understorey, the dominant species in zones 1, 2 and 3 were Curcuma mangga Val. Zone 3 produced the highest diversity. Based on the similarity index, there was a difference between the homegarden groups in zones 1, 2 and 3. Phenols and terpenoids were identified as in C.mangga.

Abstract

Essential oils obtained from Eucalyptus posses many bioactivities as fungicidal, antimicrobial, insecticidal and other activities. This study elucidated chemical compounds and antifungal activity of Eucalyptus urophylla leaves oil. Effectiveness of E. urophylla leaves oil were evaluated as antifungal against pathogenic fungi of A. niger and F. oxysporum. Eucalyptus urophylla oil was obtained by hydrodistillation method from fresh leaves of E. urophylla. Gas chromatography-mass spectrometry (GC-MS) analysis was used to analyze the chemical compounds of E. urophylla oil. Antifungal activity of E. urophylla oil was tested with in-vitro assay against A. niger and F. oxysporum strains with five levels of oil concentration (1 mg ml-1; 5 mg ml-1; 10 mg ml-1; 15 mg ml-1; 20 mg ml-1). GC-MS analysis showed the most abundant compounds of E. urophylla oil were 1,8-cineole (66.31 %), α-pinene (16.92 %), α-terpinyl acetate (6.00 %) and γ-terpinene (5.13 %). Antifungal assay showed inhibitory effects of E. urophylla against F. oxysporum with IC50 = 1.61 mg ml-1 and A. niger with IC50 = 13.56 mg ml-1. Antifungal activity of E. urophylla oil in this study was probably due to the presence of 1,8-cineole. Results indicated the possibility of E. urophylla as antifungal against F. oxysporum and A. niger.
