- ItemEfeitos da aplicação de selênio exógeno sobre a fisiologia de mudas de eucalipto cultivadas em condições de salinidade(Universidade Federal do Espírito Santo, 2023-09-28) Santos Junior, Ramon Negrão; Werner, Elias Terra; http://lattes.cnpq.br/3268068963656927; https://orcid.org/0000-0001-9047-7758; http://lattes.cnpq.br/5690784996911527; Falqueto, Antelmo Ralph; http://lattes.cnpq.br/2005727951505420; Cavatte, Paulo Cezar; http://lattes.cnpq.br/8029279967950425; Vitoria, Angela Pierre; Rodrigues Filho, JosineiSelenium (Se) is not yet considered an essential element for plant metabolism. However, it is well documented that in adequate doses Se can be beneficial to plants and improve stress tolerance mechanisms. In this scenario, the objective of this work was to evaluate the effects of applying Se (0, 1, 5 and 25 μM) in two eucalyptus genotypes (VCC 865 and AEC 0144) cultivated or not in saline conditions (0 and 100 mM NaCl). The experiment was carried out in a completely randomized design and each genotype consisted of an independent experiment. After 60 days of treatment, growth, biomass, concentration of ions (K+, Na+ and Ca2+) in plant tissues, chlorophyll a fluorescence, gas exchange and pigment content were evaluated. The data obtained were submitted to ANOVA and compared using the Duncan test (p < 0.05). The observed results showed that salinity significantly affected the height, collar diameter (Dc), biomass, net photosynthetic rate (PN), transpiration rate (TR), stomatal conductance (gs), maximal quantum efficiency of PSII (FV/ FM), the concentration of K+, Na+ and Ca2+ ions in plant tissues. However, the application of Se was able to increase the concentration of K+ in the roots, reduce the concentration of Na+ in the leaves and attenuate the disturbances observed in the L-band and in the other parameters of the JIP test (Area, ABS/RC, RE0/RC, ϕP0, ψE0, ϕE0, δR0, ϕR0, PIABS e PItotal). The same effects were not observed on the K-band. The content of chloroplast pigments was also not influenced by salinity or Se application. Finally, it was concluded that the application of 1 and 5 μM of Se was able to reduce the concentration of Na+ in the leaves, improving cellular homeostasis, the performance of the light-harvesting complex II and energy conservation in the photosynthetic apparatus of VCC 865 and AEC 0144 seedlings.

- ItemSuficiência amostral, superação de dormência, características fisiológicas, fitoquímicas e fitormonais, óleos essenciais e mecanismos alelopáticos na propagação de Passiflora spp.(Universidade Federal do Espírito Santo, 2023-02-17) Lima, Paula Aparecida Muniz de; Lopes, José Carlos; https://orcid.org/0000-0002-4880-0547; http://lattes.cnpq.br/1183524198654764; https://orcid.org/0000000316011786; http://lattes.cnpq.br/3743426965294848; Ferreira, Adesio; https://orcid.org/0000000270001725; http://lattes.cnpq.br/5400370038397801; Mengarda, Liana Hilda Golin; https://orcid.org/0000-0002-8462-3701; http://lattes.cnpq.br/4212047276110003; Freitas, Allan Rocha de; http://lattes.cnpq.br/3436114117792924; Maciel, Khetrin SilvaPassion fruit trees have an important role in Brazilian fruit growing. For many genotypes and hybrids, however, essential information is lacking to guide the propagation process and, therefore, the success of their cultivation. The objective of this work was to study and analyze the sample sufficiency, aspects related to dormancy and physiological, phytochemical and phytohormonal characteristics of seeds, the effect of using essential oils to control fungi in seeds and allelopathic mechanisms in the propagation of Passiflora spp. For experiments on overcoming dormancy, physiological, biochemical, phytohormonal characteristics and the use of essential oils, seeds of P. mucronata genotypes were used. Essential oils in the control of fungal contamination was analyzed in yellow and purple passion fruit seeds. The following were analyzed: germination, vigor, reserve substances and hormones. For analysis of allelopathy, bark extract of P. mucronata genotypes was used on the germination and vigor of Lactuca sativa seeds. For the analysis of sample sufficiency, seeds of the passion fruit hybrid (BRS Rubi do Cerrado – BRS RC) were used. The following parameters were analyzed: germination, germination speed index, shoot and root length, dry mass of normal seedlings and the ratio of root length to shoot length. The seeds of P. mucronata show integumentary dormancy. Treatments with mechanical scarification and immersion in sulfuric acid do not overcome seed dormancy of P. mucronata genotypes. The temperatures of 60 and 70 °C overcame the dormancy of seeds of the P. mucronata genotypes and provided greater germination and vigor. Seeds of P. mucronata genotypes G3, G7 and G8 showed greater germination and vigor when submitted to treatments to overcome dormancy. Seeds of the G2 and G8 genotypes showed the highest means of germination and vigor. Seeds of P. mucronata genotypes submitted to thermotherapy treatment have lower averages of nutritional reserves. Seeds of the G6 genotype have lower averages of germination, vigor, nutritional reserves and hormones. Seeds of the G2 genotype show higher averages of proteins and lipids, and of the AIA hormones, proline, ethylene precursor ACC, spermine and spermidine. Essential oils of citronella and cinnamon are efficient in controlling fungi in Passiflora spp seeds. The essential oils of citronella and cinnamon affect the germination and vigor of the studied P. mucronata seeds. Cinnamon oil at a concentration of 0.5% is efficient in controlling fungi and does not affect the physiological quality of Passiflora spp seeds. L. sativa seeds have their physiological cycle affected by allelopathic substances present in the peel of P. mucronata fruits. The concentration of bark extracts from 50% inhibits the germination of L. sativa seeds. For passion fruit seeds, the behavior of the experiment and the adjustment was the same, regardless of the variable, number of repetitions and treatment, with and without saline stress. Using 14 repetitions, regardless of the number of seeds, there is a 50% reduction in the amplitude of the bootstrap confidence interval.
- ItemUsing digital mapping and artificial intelligence to predict soil quality in the central portion of the Itapemirim river basin, southeastern Brazil(Universidade Federal do Espírito Santo, 2023-08-31) Barbosa, Kargean Vianna; Burak, Diego Lang; https://orcid.org/0000000267583517; http://lattes.cnpq.br/2501042964619476; https://orcid.org/0000-0002-8184-607X; http://lattes.cnpq.br/5279932752748851; Camelo, Danilo de Lima; https://orcid.org/0000000298018772; http://lattes.cnpq.br/0620489716195442; Santos, Alexandre Rosa dos; https://orcid.org/0000000326179451; http://lattes.cnpq.br/7125826645310758; Temporim, Filipe Altoe; Costa, David de AndradeSet against the backdrop of the Itapemirim River Basin, this multifaceted research delves deep into the geochemical intricacies, predictive modeling, and agricultural potential of the region's soils. Chapter one embarks on a geochemical exploration, emphasizing the significance of environmental quality, particularly in the context of trace elements arising from anthropogenic or geogenic activities. Through a rigorous analysis of soil samples in regions marked by bimodal magmatism, the study establishes correlations between trace elements and soil components, pointing to the potential influence of geological processes on soil quality. Chapter two shifts’ gears, leveraging the combined power of Sentinel-2 and Landsat-8 satellite datasets, processed via the Google Earth Engine platform. Machine-learning algorithms, from Decision Trees to Gradient Boosting, are employed to predict Soil Organic Carbon (SOC) and Total Nitrogen (TN) concentrations, with particular emphasis on low-intervention pasturelands in southeast Brazil. The findings accentuate the efficacy of machine learning models, especially when paired with high-resolution satellite data. In the final chapter, a revolutionary approach to Multicriteria Analysis Modelling is unveiled. This hybrid methodology marries the deterministic nature of algebraic map procedures with the predictive prowess of machine learning, culminating in a comprehensive Farming Favorability Index (FFI) for the region. The results offer a granular insight into the areas primed for agriculture, with the accompanying uncertainty map serving as a cautionary tale.

Espírito Santo (ES) is the second largest coffee producer in Brazil, being the largest producer of C. canephora and the third largest producer of C. arabica. The incidence of diseases in coffee plants represents one of the most limiting barriers to maintaining and increasing production and productivity in the agricultural scenario, with emphasis on coffee leaf rust (Hemileia Vastatrix). Knowledge of areas with climatic suitability for planting coffee tree and the favorable climate for the occurrence of coffee leaf rust in the state of Espírito Santo, are sine qua non conditions to assist in the sustainable management of coffee leaf rust in the state. Thus, the objective of this work was to determine the areas of climatic suitability for the planting of C. arabica and C. canephora and the climatic favorableness for the occurrence of coffee leaf rust in the state of Espírito Santo. The areas suitable for planting C. arabica and C. canephora corresponded, respectively, to 66.50 and 21.17%. The suitable areas with some type of restriction added up to 8.03% for C. canephora and 15.74% for C. arabica. Meanwhile, unsuitable and inappropriate areas for C. canephora and C. arabica corresponded, respectively, to 25.47 and 63.09%. The state of ES has 92.22% of its territory with climate favorable for the occurrence of coffee leaf rust (H. Vastatrix). Based on climate zoning and climate favorable conditions for the occurrence of coffee leaf rust, it is possible to plan the planting of coffee tree in their respective areas of suitability, in addition to planting more susceptible materials in regions unsuitable for the occurrence of coffee leaf rust and the more resistant in areas favorable to occurrence, helping in monitoring and decision-making for the use of fungicides. In this way, it becomes an important tool for establishing areas for cultivation of C. canephora and C. arabica, for the sustainable management of the disease.
