The estimation of stability performance of the cultivars becomes most important to detect consistently performing and high yielding genotypes. Eleven Arabica coffee genotypes were evaluated in southwestern part of the Ethiopia across four locations for two consecutive years (2014/15 - 2015/16). The objective of the study was to estimate the presence of the interaction between genotypes and environments; and the stability performance of the coffee cultivars for its bean yield. The experimental design was Randomized Complete Block Design (RCBD) replicated twice in each testing location. Genotypes were evaluated by Genotype main effect and genotype x environment interaction (GGE) biplot. The combined analysis of variance indicated that genotypes, environments and GEI showed highly significant (p<0.01). Total variation explained was 41.63% for environments, 9.31% for genotypes and 32.32% for genotype by environment interaction (GEI). This obviously shows that the effect of the genotypes to the total variance was minimal when compare to the environment and the GEI. GGE biplot grouped the environments into four clusters with five genotypes being the winners in different group of environments. Top yielding cultivars namely; L52/2001 and L55/2001; and E6 (Jimma 2015/16) were identified as an ideal genotype and environment, respectively. In this study, stable genotypes, suitable environment for each of the coffee genotype and environment similarity based on bean yield were identified.","PeriodicalId":7478,"journal":{"name":"American Journal of BioScience","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82682803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blood serum biochemical parameters and pathological changes were perused. Twelve male goats were randomly divided into 4 equal groups, G1 (infected-untreated), G2 (infected- BAF-EE treated), G3 (infected-albendazole treated) and G4 (uninfected-BAF-EE treated). Experimental infection was conducted with a single oral dose of 10x3 infective third larval stage (L3) of H. contortus at 0-time, whereas treatment with BAF-EE and albendazole was given at a single oral dose of 9g and 5mg/kg body wieght respectively in the 5th week post infection (PI). Blood samples were drawn on zero time, 3rd week PI and then biweekly till the 9th week for serum biochemical analyses. At the end of the experiment, all animals were slaughtered to estimate histopathological alterations in the abomasal and hepatic tissues. Serum biochemistry of infected animals showed significant depression of total serum protein (TP), albumin, albumin/globulin (A/G) ratio, total antioxidant capacity (TAC) and calcium (Ca) levels compared to uninfected goats. Significant elevation was observed in values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (γGT), cholesterol, urea and creatinine of infected animals, while no significant differences were recorded in levels of inorganic phosphorus (P), potassium (K), sodium (Na), chloride (Cl) and total iron binding capacity (TIBC). Histopathological studies conducted on abomasa of infected-untreated animals revealed inflammation, necrosis, petechial hemorrhages and intense cellular infiltration. Liver showed bile duct hyperplasia, degeneration of hepatocytes and cell infiltration. Histopathological alterations in tissues of infected – treated animals were lower in intensity than those of infected-untreated goats. Results of the present experiment demonstrated that BAF-EE has an anti-parasitic and hepatoprotective effects as well as it improves serum biochemical alterations and oxidative stress in goats infected with H. contortus parasite.

Data for about eight quantitative traits were recorded only once in experimental period, while the yield data were recorded for six consecutive cropping seasons. Cluster, genetic divergence, and principal component analysis were used to assess the variability among the genotypes. The results revealed that average linkage cluster analysis for nine traits grouped the germplasm accessions in to three clusters. The number of accessions per cluster ranged from three in cluster III to 25 in cluster II. The clustering pattern of the coffee accessions revealed that the prevalence of moderate genetic diversity in Limmu coffee for the characters studied. The maximum inter-cluster distance was observed between clusters II and III; whereas the minimum inter-cluster distance was observed between clusters I and II. The study highlighted the possibility of using accessions of the distant clusters as potential candidates for the genetic improvement of Limmu coffee through hybridization. Moreover, the principal component analysis showed that the first four PCs extracted about 82% of the total variance of the 49 coffee germplasm accessions and also confirmed moderate diversity among the germplasm accessions since the entire variation cannot be explained in terms of few PCs. This, in turn, indicates that the involvement of a number of traits in contributing towards the overall diversity.","PeriodicalId":7478,"journal":{"name":"American Journal of BioScience","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82960376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, low-cost adsorbents (rice husk ash (RHA) and silica (RHS)) were prepared from rice husks purchased locally from a rice mill industry and characterised. While the crystallinity and mineralogy of the adsorbents were analysed using powdered XRD crystallography, analysis of the physico-chemical properties was performed using standard procedures. Elemental analysis (CHN) was done using Perkin Elmer CHN elemental analyser and FTIR Spectrometer was used to determine the functional groups on the surface of the adsorbents at room temperature. The prepared samples were used as adsorbents for the removal of chromate (VI) ion in a batch sorption process with reaction conditions vis–a-viz adsorbent dosage = 0.5 g, adsorbate volume = 500 ml, adsorbate solution concentrations: 10-200 mg/l, time = 4 h, temperature = ambient temperature. The residual Cr (VI) concentration in the solution was analyzed spectrophotometrically at λ = 540 nm following the 1,5–diphenylcarbazide procedure. Results obtained for the characterisation of the adsorbents were similar and comparable with what obtained in literatures. Physico - chemical analysis revealed a high ash content of 89% and silica content of 95.83%. XRD analysis for the rice husk ash samples reflected the presence of cristobalite (SiO2) in amorphous form and a characteristics broad peak at 2θ angle = 26.5°. FTIR analysis revealed the presence of silanol groups (Si-OH), silicic acid (Si-O-Si-OH) in the ash and Si-O-Si and Si-O) in the silica. The results of effect of time-concentration experiments of chromium ion sorption by the adsorbents revealed that Cr (VI) ion sorption was both time and initial solution concentration dependent with over 80% removal achieved within the first 30 min of contact for both adsorbents as the initial chromate concentration was increased.

Where, enhanced grain yield has been achieved in bread wheat (Tritium aestivum L.) through the development of adaptable, high-yielding, and rust-resistant genotypes by evaluating advanced genotypes for yield in multi-environment trials. The adaptability of a genotype over diverse environments is usually tested by the degree of its interaction with different environments under which it is grown. This study examines fifteen bread wheat genotypes for two consecutive years (2016 and 2017) across eight locations in Ethiopia. The experiment was laid out using a Randomized Complete Block design and replicated three times intending to determine high-yielding advanced genotype and release best performing genotypes as a variety for the end-user. Highly significant (P ≤ 0.001) effects of genotype, environment, and genotype by environment interaction were observed for grain yield. The AMMI analysis of variance indicated that environments accounted for 52.34% of the total sum of squares for grain yield (genotype yields ranged from 5.76 t/ha at E-11 to 1.31 t/ha at E-7). followed by interaction (22.95%) and genotypes (11.31%).The genotype ETBW8260 (G4) exhibited high mean grain yield and well performed to the tested environments. The ETBW8260 (G4) was selected as early maturing, high yielding, resistant to yellow rust and fitting for low to midland wheat growing areas and has a yield advantage over the standard Ogolcho and the local Kakaba.

Changes in neural plasticity have been shown to play a significant role in the onset and development of those mental illnesses. Mitochondria play an extremely important role in the central nervous system by being the main energy producer through the oxidative phosphorylation and being involved particularly in the regulation of cell survival or death, as well as synaptic plasticity. Neurite outgrowth is the differentiation process by which neurons establish synapses through the protrusion of neurons and their extension. Methods: Because the effects of GS dilutions on mitochondrial function and neuroplasticity remain elusive, we aimed to investigate whether a treatment with GS at low doses (centesimal dilutions, C) improved bioenergetics parameters such as ATP production, mitochondrial respiration as well as cellular glycolysis before to characterize its effects on neurite outgrowth. Nerve growth factor (NGF), which is known as a promotor of cell growth and survival, was used as a positive control. Results: Our results demonstrate that GS dilutions (3C and 5C) efficiently ameliorated the bioenergetics of SH-SY5Y neuroblastoma cells by increasing cellular ATP level and mitochondrial respiration as well as promoting the cell survival. In addition, GS dilutions significantly improved neurite extension in the 2D as well as 3D culture model after 3 days of treatment. 3C and 5C dilutions showed similar functional effects than those obtained with the positive control nerve growth factor (NGF). Conclusions: These findings indicate that GS dilutions modulate the mitochondrial bioenergetic phenotype and improve the neurite formation. The mitochondrial function improving properties of GS dilutions might represent one possible important pathway contributing to its neuroprotective effectiveness.
