In the induced fermentation process, the fermentation speed is increased, but environmental interferences with different microbiota can alter the fermentation process, making it difficult to repeat the results. The objective was to induce anaerobic fermentations in coffee fruits, through different processes, aiming at modifying the sensory profile of the beverage. The experiment was conducted in 2019, with ‘Mundo Novo IAC-379/19’ coffee fruits, which came from full harvest, with 70% of fruits in the parchment stage. On the day of harvest, the coffee was separated into 78 experimental plots, each containing 10 L. The treatments used were: addition extract of Citrus reticulata, Carica papaya, Ananas comosus, Eucalyptus spp. leaf and addition of sugar, at concentration of 10% in aqueous solution (stored in 12 L buckets) and treatment with water only. 24 and 48h fermentation periods were tested, besides two processing methods, natural and with peeled fruits. In addition, the fruits were tested without induced fermentation for natural and peeled coffee. It is concluded that the treatment with fermentation induced for 24 h without the addition of extracts in wet processing yielded coffees of better sensory quality, with a final score of 85.33. The wet processing of coffee fruits without the addition of extracts, immersed in water for 24 h, yielded better sensory quality. The addition of Ananas comosus extracts implies a reduction in the sensory quality of coffee in the induced fermentation process.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47938778","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 experiment was carried out in a protected environment, covered with a 50% shade screen, at the Federal University of Western Pará (UFOPA), Santarém PA, in 2017. Seeds were arranged in 5 L pots, containing 3.5 Kg of Yellow Latosol. For sowing, 3 seeds per pot were used and thinning occurred 7 days after seedling emergence, leaving only the most vigorous. The experimental design used was randomized blocks, with subdivided plots, where the plots were the doses of biofertilizer (50, 100, 150 and 200 mL plant-1 + mineral fertilizer) and the subplots, the time periods: T1 (0 to 20 days), T2 (24 to 33 days), T3 (37 to 47 days) and T4 (51 to 61 days), containing five repetitions. Plant height, stem diameter, absolute stem growth rate and absolute growth rate in stem thickness were evaluated. The greatest growth of cowpea was obtained in treatments with mineral fertilization. The dose of 200 mL plant-1 of the biofertilizer showed results close to mineral fertilization, in different vegetative stages. Cowpea plants, starting at 45 DAE, tend to stabilize their growth in diameter.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46528380","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 objective of this work was to evaluate the incidence of fungi associated with yellow passion fruit seeds in the State of Maranhão. The experiment was carried out in 2014 and conducted at the Seed Laboratory of the State University of Southern Maranhão (UEMASUL), Campus Imperatriz. Fruit seeds collected from six municipalities in the state of Maranhão (Carolina, Capinzal do Norte, Estreito, Imperatriz, Vila Nova dos Martírios and São Luís) were used. A completely randomized design with four replications was adopted. A total of 400 seeds were used per municipality, 50 per gerbox, totaling the processing and analysis of 2400 seeds in general. The incidence of pathogenic agents in the seeds was determined by using the filter paper method with freezing, using four replications of 100 seeds per evaluated municipality. Seven days later, the incidence of pathogens was estimated by using a stereomicroscope, with confirmation of the genus and/or species of the fungus. The incidence of Penicillium sp. in yellow passion fruit seeds occurred in all assessed municipalities collected. The city of Vila Nova dos Martírios has presented the highest incidence of fungi, while the city of Imperatriz has had the lowest rate.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49495856","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}

Due to the dependence on these bare-root plants, Brazilian producers use early cultivars, which start the leaves emission and the flower buds differentiation in advance, since these bare-root plants do not always arrive within the estimated time for planting in southern Brazil. The objective of the work was to investigate whether six strawberry cultivars, produced in a greenhouse, differ in their phyllochron, and root system development. Six cultivars were tested, arranged in a randomized block design, with four replications. Bare-root plants were cultivated in soil in a greenhouse. The phyllochron was evaluated by counting the number of leaves, weekly, from the beginning of leaf emission (from the main crown) until the appearance of the first fruit. The roots were digitized by a scanner and the images analyzed by the WinRHIZO® software. ‘Camarosa’ cultivar was considered the earliest to start fruiting, as it had the lowest phyllochron value (69.93ºC day-1 leaf-1), while the cultivar ‘San Andreas’ was the latest (166.67ºC day-1 leaf-1). ‘Albion’ and ‘Aromas’ presented the highest total root length in relation to the other cultivars. In conclusion, the six strawberry cultivars analyzed in this study, with different photoperiodic classifications regarding flowering, differ in relation to their morphophenological performance. In the growing conditions of southern Brazil, phyllochron study indicates that ‘Camarosa’ cultivar is the earliest and ‘San Andreas’ cultivar is the latest. ‘Albion’ and ‘Aromas’ cultivars are more compact plants, with greater potential for the development of the root system.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46456689","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}

Increased forage accumulation may be favored by technologies such as inoculation. Research works on this theme have been conducted with Azospirillum brasilense associated to oats, ryegrass and guinea grass. However, response of jiggs, a widely cultivated perennial grass, to plant growth-promoting microrganisms is poorly understood. Hence this study aimed to assess effects of inoculation on development of Cynodon dactylon cv. Jiggs. Four treatments were tested: T1) control, T2) Inoculation with A. brasilense, T3) Inoculation with Azospirillum, Rhizobium, Pseudomonas and Saccharomyces, T4) Inoculation + Reinoculation with Azospirillum, Rhizobium, Pseudomonas and Saccharomyces. Forage mass, percentage of leaves, stems, dead mass, reproductive structures and leaf/stem ratio were measured. Data were submitted to analysis of variance, and when significant effects were detected, means were separated by LSD Test. Positive effects of inoculation were recorded at all evaluations, mostly concerning percentage of leaves and leaf/stem ratio. A. brasilense improved leaf/stem ratio up to 56%. Also, a 64% increment on this parameter was obtained with Azospirillum, Rhizobium, Pseudomonas and Saccharomyces. Modifications of plant morphology components are important since grasses with more percentage of leaves increase nutritional value of haylage. Morphology of Cynodon dactylon cv.

Then, the extract was subjected to sterilization along with the BDA medium in autoclave at 120oC for 20 min, they were then put in petri dishes for later evaluation of the mycelium root growth compared with the control. The fungi Pycnoporus sanguineus presented higher fungal activity, obtaining total inhibition of all treatments and extract concentrations, however, for the fungi Gloeophyllum trabeum, the 100 g L -1 concentration warmed in water bath obtained a better result than the others. Therefore, it can be concluded that the Cinnamomum zeylanicum aqueous extract presented inhibitory potential.
