This study was carried out to determine the diversity in tomato fruits ( Solanum spp.) using eight conventional descriptors (CD) and 47 Tomato software descriptors Analyzer (TA), related to the morphometry of the fruits. The phenotyping of 50 accessions selected by the morphological variation of the National Bank of Genetic Resources was carried out. A variability was detected for the characteristics of the fruit with CD and quantified by TA. In the phenotyping of 50 accessions selected by the morphological variation of the National Bank of Genetic Resources a variability was detected for the characteristics of the fruit with CD and quantified by TA. The shape of the fruit was the main character used for the visual grouping of accessions in ten different varietal groupings: Circular (26 %), Flattened (20 %), Obo-val (20 %), Pyriform (12 %), Elliptical (6 %), Cordate (6 %), Cylindrical (4 %), Oblong (2 %), Oval (2 %) and Flattened (2 %) and very small to large in size. Significant variation was observed for fruit weight (3.75-217.44 g), equatorial diameter (17.85-75.55 mm), polar diameter (17.57-96.76 mm), perimeter (61.86-312.64 mm) and area (249.56-6367.57 mm). The principal component analyzes analysis contributed to the total variation and the first two explained 30.02 % of the variation where the fruit shape index and the shape of the proximal/distal end of the fruit showed a high contribution to the variation of the first component. There was a strong positive correlation between fruit shape and size, while negative correlations were between fruit shape index, internal eccentricity, and proximal end shape. The results have shown that the TA and CD software descriptors are a powerful tool for the characterization and classification of tomato landraces, as well as for distinguishing between groups of related cultivars. This has important implications for the improvement and protection of local tomato varieties.","PeriodicalId":53763,"journal":{"name":"Journal of the Selva Andina Research Society","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46070035","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 nature, there are genera and species of aerobic heterotrophic microorganisms, native to all environments, that have the potential capacity to degrade kerosene, such as some genera and species of yeast, to synthesize protein of unicellular origin or to bioaugment the negative environmental impact of kerosene. for the above. The objective of this work was to analyze the ability of Saccharomyces exiguus to use kerosene as a carbon and energy source. For this, S. exiguus was isolated from oil wells, it was grown in 5% kerosene with 1.2% NH 4 Cl and 50 ppm yeast extract. The growth of S. exiguus in kerosene was analyzed using the response variables: dry weight, protein quantification, and gas chromatography showed the use of kerosene components as a carbon and energy source. The results showed that S. exiguus can use the aliphatic and aromatic hydrocarbons of kerosene as the only source of carbon and energy, this potential is applicable to synthesize unicellular protein or in the recovery of environments impacted by kerosene.","PeriodicalId":53763,"journal":{"name":"Journal of the Selva Andina Research Society","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69649109","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}

When Hv is grown through an intensive agricultural system, based on the application of chemical fertilizers and pesticides. The Hv grains transported, stored and marketed under inappropriate conditions in Morelia, allow the growth of Aspergillus genera and species that potentially synthesize mycotoxins such as ochratoxin A. The objectives of this research were i) to analyze the density of Aspergillus in grains of Hv , commercialized in Morelia, Mich, Mexico, ii) Demonstrate the potential capacity of A. fumigatus isolated from Hv in Sabouraud dextrose agar (SDA) to synthesize ochratoxin A. Therefore, Hv grains collected in Morelia, Mich was used to determine the density and diversity of Aspergillus species. As the potential capacity of the main species isolated: A. fumigatus in SDA for the synthesis of ochratoxin A was analyzed without no problem since chemical composition of SDA was enough for nutritional demand for A. fumigatus . All experimental data were analyzed by ANOVA/Tukey. The results indicate a relatively high number of propagules of A. fumigatus that contaminate the grains of Hv commercialized in Morelia, where 67 % of the isolates of A. fumigatus showed the potential to synthesize ochratoxin A in SDA. It is concluded that there is an evident risk for humans and animals that consume barley ( Hv) contaminated by A. fumigatus that potentially generate ochratoxin A, for which health care is required in the handling and commercialization of Hv , in Morelia City.","PeriodicalId":53763,"journal":{"name":"Journal of the Selva Andina Research Society","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44065082","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}
