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

The improvement of low nitrogen tolerant hybrid maize face on genotype x environment the genotype x environment interaction caused a genotype unable to maintain its appearance under suboptimal conditions. it caused the breeders difficult to choose varieties that are stable at optimal and suboptimal conditions. The using of simultaneous stability analysis methods can provide more authentic stability information. This study aims to 1) determine the yield stability of the promising low N tolerance hybrid maize varieties, 2) to obtain varieties that have high yield and stability and under optimal and sub-optimal conditions. This research was conducted at Bajeng Experimental farm, Gowa, South Sulawesi. The research was arranged in a split-plot design with two replications. Three levels of fertilizer N (N0 = 0 kg N ha-1, N1 = 100 kg N ha-1 and N2 = 200 kg N ha-1) as the main plot and 39 genotypes of maize (36 hybrids resulting from crosses of low N and 3 checks varieties Nasa 29, Bisi 18 and Jakorin 1) as the subplot. The variable measured was grain yield. The yield stability analyses were performed by Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, and GGE Biplot methods. The results showed that there were no genotypes stable in overall the four methods, but three genotypes considered as stable genotype based on two methods. H5, H6 and H15 genotype were the genotypes with high stability and high yield. The three genotypes had the opportunity to be released as a low Nitrogen tolerant maize hybrid.

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

Microwave treatment on white pepper was conducted to damage cell tissue to facilitate the distillation and increase the yield of essential oils. The research objective was to determine the effect of pepper varieties and microwave treatment on the profiles of volatile compounds and the characteristics of white pepper essential oils. The research was conducted with 50 grams of white pepper placed into a 15 cm diameter petri dish and put in a microwave oven at the power of 600 watts for 90 seconds then white pepper milled by hammer mill. Essential oils were obtained using the water distillation method then were tested for their characteristics and compounds using Gas chromatography-Mass Spectrometry (GC-MS). White pepper was analyzed using the water content, piperine content, and its cell tissue microstructure was analyzed using Scanning Electron Microscope (SEM). The results showed that different pepper as accession produced different profiles of volatile compounds, characteristics, and antioxidant activity (p<0.05). The number of volatile compounds of white pepper essential oils identified by GC-MS was 42, where the largest compound was β-caryophyllene (50.51%). Microwave treatment damaged the cell wall of white pepper, lowered water content (17.43%), increased piperine content (10.57%) and essential oil yield (25%), and changed the profiles of volatile compounds of essential oils of Lampung daun lebar accession. Color became bluer (b*value rises by 201.99%), increased specific gravity (1.27%) and antioxidant activity (7.4%), decreased solubility in 95% ethanol (17.95%) and acid number (20.8%) while the refractive index was not affected by pepper accessions and microwave treatment.

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.
