The main tree and shrub species related to saproxylic beetles are reported and the beetle species diversity is presented in a table. Of the species listed in the table, 36 species of saproxylic beetles are related to Populus sp. (Populus diversifolia and P. pruinosa), 21 species to Elaeagnus angustifolia, 20 species to Tamarix sp., and 17 species to Salix sp. The least number of saproxylic beetles was related to Fraxinus sogdiana (2 species) and Halimodendron halodendron (3 species). The author detected data about the representatives of the following families of Coleoptera: Brentidae, Bostrichidae, Buprestidae, Cerambycidae, and Curculionidae on the territory of tugai forests and the arid zone of Kazakhstan. According to the used references, the most numbered family of saproxylic beetles in the tugai forests is Buprestidae: 41 species have been known. The author found out data about 17 species of Curculionidae and 10 species of Cerambycidae. Other families have a lower number of species. It means that Buprestidae is the most studied family in the tugai forests of Kazakhstan. Further research is necessary to extend knowledge about the diversity of saproxylic beetles in the tugai forests of Kazakhstan.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2478/sab-2018-0016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42668067","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}

BLB disease incidence in West Africa was between 70–85% and yield loss in farmers’ fields was in the range of 50–90% from 2005 to 2010. In the present study, African Xoo virulence gene OPP-172000 DNA marker was identified and purified using randomly amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) products from 50 Xoo isolates. Genomic DNA of 50 Xoo isolates were analyzed using OPP-17 primer in RAPD-PCR during which African Xoo virulence gene OPP-172000 DNA marker was identified, purified, cloned, and sequenced. Cloning and DNA sequencing of African Xoo virulence gene OPP-172000 DNA generated a 1953 bp nucleotide sequence consequently tagged as AXaVrg-1953. BLAST homologous analysis of the AXaVrg-1953 sequence provides comprehensive identification of the type II secretion genes and secreted proteins, type III secretion genes and secreted proteins in African Xoo virulence gene. Phylogenetic unweighted pairgroup method arithmetic (UPGMA) analysis revealed the African AXaVrg-1953 sequence was distinct from the other Xoo virulence gene sequences from China, Japan, Korea, Germany, and the United States. This information is potentially useful for effective management of BLB disease in West Africa.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48842019","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}

Barley flour (BF) decreased both protein content and quality by approximately 1.5 and 50%, respectively. In blends, hemp fine flour containing recovered protein level back. BF lowered amylases activity by about 20–25% in maximum; hemp products had no significant effect. Farinograph water absorption was magnified by additions of both alternative flours. Considerable shortening of dough stability and decrease of resistance against over-mixing occurred for all flour tri-composites. Extensigraph dough elasticity increased and extensibility diminished. After dough resting taking 30 min, extensigraph energy of the control sample fell from 141 cm2 to a half as barley flour portion increased. In cereal composites, hemp products demonstrated reversal tendencies. BF lowered water suspension viscosity, but hemp wholemeal H4 and especially fine hemp flour H7 caused a recovery of amylograph maxima to level comparable with wheat control. Correlation analysis confirmed analytical and rheological data agreement – the extensigraph elasticity or energy could be predicted according to the Zeleny value, or the amylograph maximum according to the Falling Number (r = 0.79, 0.90, and 0.65, respectively; P = 99.9%).","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45365345","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}

The Czech Republic and the Slovak Republic were able to draw on EU funds to support the formation of producer groups. Main objective was to investigate whether the funds have led to an increase of value added of products placed on the market. In the Czech Republic and the Slovak Republic during the reporting period the sum of 44 million EUR was provided to support the establishment of marketing organizations, 305 producer groups were supported. Many of the supported entities are no longer active. In the Czech Republic, only 15 entities are still operating, but they do not have a significant impact on the increase of value added of the agricultural sector. In the Slovak Republic, entities supported in the first programming period (2004–2006) have a higher share of the generated value added. During the second funding period (2007–2013), the supported groups showed a negative value added. Given the characteristics of supported groups, the number of successfully supported groups, the reported features and the total value of generated value added, it can be suggested that most of the entities were established due to the relative ease of fundraising.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43747974","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}

The study investigated the drivers of informal sector participation by SMEs in Ghana and made use of a Chi-square statistical methodology to analyze the drivers of SME participation in the informal sector of Ghana. Analyses from the study showed that gender can be deemed as a driver for SME participation in the informal sector of Ghana. Gender was significant at 0.012 with registration of business enterprise and 0.055 with tax obligation of respondents. The educational level of SME operators had an impact on registration and tax obligation and therefore can be deemed as a driver of SME participation in the informal sector of Ghana. However, the level of education was insignificant to registration and tax obligation but had a strong correlation to these variables. The study also showed that women are more likely to participate in the informal sector of Ghana as compared to men and also that there is a high tendency of not paying tax among SME operators in the informal sector of Ghana. A very low educational level among SME participants was recorded with over 60% of the respondents not having any formal education. Based on the findings of the study, a country-wide research can be done to ascertain the socio-economic determinants of informal sector participation in Ghana. Also, the study highly recommends policies that can harness the usefulness of informal sector.","PeriodicalId":53537,"journal":{"name":"Scientia Agriculturae Bohemica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44594271","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}
