However, there is no standard for determining the compressive strength of charcoal beds. Thus, the objective of this work was to evaluate some test parameters for determining the generation of charcoal fines in a manual hydraulic press. Charcoal was produced with eucalyptus logs 7 years old, diameters of 10 to 12 cm, and length of 1 m in a circular surface kiln, with a maximum carbonization temperature of 400 ºC and a total time of 58 hours. For methodology evaluation, charcoal mechanical tests were performed in a manual hydraulic press, using as test variables four charcoal granulometric ranges (12.7 to 19.5; 19.5 to 25.4; 25.4 to 31.7 and 31.7 to 50.8 mm) and five compressive loads (1; 1.5; 2; 3 and 5 t). The reference was the drum test. The method of evaluating the mechanical strength using a manual hydraulic press is suitable for determining the strength of a charcoal bed, because it represents the efforts that charcoal supports in industrial systems. The test parameters recommended for determining the mechanical strength of charcoal, using a manual hydraulic press, are: compressive load of one ton; charcoal with granulometry of 19.5 to 50.8 mm; average velocity of force application of 1 mm s -1 ; and, charcoal time under pressure equal to 1 min.","PeriodicalId":21187,"journal":{"name":"Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83128701","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}

This work aimed to evaluate pollen viability and stigma receptivity in different Lima bean genotypes throughout the day. Accessions ‘Roxinha -MT’ and ‘Cana Longa-PB’ were used in the experiment. Five flower buds were collected from each genotype at 6:00 a.m., 10:00 a.m., 2:00 p.m., and 6:00 p.m. The stigma receptivity was determined using 3% hydrogen peroxide, whereas pollen viability was determined with 2% acetocarmine colouration. The genotype and time factors acted independently on the percentage of viable and non-viable pollen grains and stigma receptivity. The genotype ‘Roxinha’ presented 88.54% viable pollen grains, a value 84.27% higher than that of the ‘Cana Longa’ genotype. This percentage varied as a function of time, with the highest means observed at 6:00 a.m. Stigma receptivity was influenced only by the time of the day, undergoing a great reduction in receptivity, from 88% in the early morning to slightly more than 40% around noon.
