Clones de batata-doce foram avaliados em Vitória da Conquista, experimento, composto por 16 clones oriundos Janaúba (MG), Viçosa Bom Jardim Minas Gurupi (TO), Santo Antônio Platina (PR), Holambra II (SP), Conquista (BA) e Condeúba (BA). Os foram: 1; 2; 7; 9; 14; 15; 17; 19; 23; 25; 29; 30; 36; 38; 44 100. Utilizou-se o delineamento blocos casualizados, com tratamentos 3 repetições. Foram avaliadas as características das raízes tuberosas: produtividade total, peso médio comercial,...
One of the greatest barriers to commercial marketing fresh-cut fruit is limited shelf-life due tissue softening and surface browning. Moreover, development microorganisms on can compromise safety product. Edible coatings have been proposed as postharvest treatments maintain quality prolong shelf-life. The present work aims evaluate effect chitosan in physical, chemical, nutritional microbiological characteristics minimally processed 'Rocha' pear. Fruits were peeled, cut into slices immersed...
A alta perecibilidade da mandioca (Manihot esculenta, Crantz) in natura faz com que o consumo seja feito dentro de um período curto após a colheita. principal causa perda se deve à deterioração fisiológica, atribuída atividade enzima peroxidase (E.C.1.11.1.7). Este trabalho objetivou avaliar efeito combinado diferentes inibidores nas concentrações 1, 5 e 10 mM em raízes variedade Cacau Amarela. As foram tratadas por uma hora soluções ácido ascórbico, bissulfito sódio, Na2-EDTA, L-cisteína...
In order to evaluate the physical-chemical characteristics of nineteen sweet cassava varieties (Milagrosa, Paraguai, Maragogipe, IAC 576-70, Saracura, Amarela Viçosa, Guaxupé, Manteiga, Aipim Furadinho, Calombo, BRS Dourada, Rosa, Manteigão, Pão da China, Gema de Ovo, Colombo, Eucalipto, Cacau Branca and Rosada) this study was conducted at State University Southwest Bahia, in Vitoria Conquista – BA. It evaluated pH, soluble solids, acidity, texture, cooking time, starch, amylose, amylopectin...
O objetivo deste trabalho foi avaliar o efeito do pré-resfriamento e da embalagem PET na conservação pós-colheita salsa lisa cv.Graúda Portuguesa
In order to evaluate the effect of nitrogen on levels HCN, chlorophyll, and protein in cassava plants (Manihot esculenta Crantz), two experiments were carried out at State University Southwestern Bahia (in Vitória da Conquista, Bahia, Brazil). this field study, six treatments conducted (0, 50, 100, 200, 300, 400 kg ha-1) varieties (Sergipe Lisona), using experimental delineation randomized blocks, with arranged a factorial scheme. Results showed level cyanhydric acid leaves, 90 days after...
O paclobutrazol pode atenuar os efeitos negativos do estresse hídrico em diversas espécies vegetais, todavia, para cafeeiros é necessário ampliar a base de conhecimentos sobre este tema. Neste estudo, objetivou-se avaliar morfofisiologia plantas jovens Coffea arabica var. ‘Catuaí Vermelho IAC 144’ resposta diferentes regimes hídricos e concentrações aplicado via solo. experimento foi conduzido casa vegetação Vitória da Conquista, BA. delineamento experimental blocos casualizados, com esquema...
The use of shading and paclobutrazol in coffee plants can be an important cultivation strategy to mitigate the negative effects high solar radiation atmospheric temperature. Therefore, levels photosynthetic pigments foliar gas exchanges young submitted doses were evaluated, environments with artificial light restriction. Five experiments performed: one full sunlight four artificially shaded black polyethylene meshes at 20%, 40%, 60% 80% In each these environments, experiment was carried out,...
Abstract Cereal rye ( Secale cereale sp.) is a cover crop species known to improve soil and water quality. Late‐season biomass production information growers need maximize benefits schedule field operations. Statistical learning, built upon statistical computational algorithms that “learn” from data, may help predictions of as function initial inorganic nitrogen levels. Three models—Least Absolute Shrinkage Selection Operator (LASSO), Ridge, Random Forest (RF)—were trained optimized on 3‐yr...
The purpose of this study was to evaluate the efficiency ethylene absorber potassium permanganate (KMnO4) on postharvest longevity Epidendrum ibaguense Kunth flowers. KMnO4 in form sachets containing vermiculite were fixed 1.5-L sealed glass bell jars. flowers placed vases with distilled water (250 ml) within jars and 0.25, 0.50, 0.75 1.0 g per sachet. Flower stems maintained or out absence used as controls. experiment conducted a randomized block design, where plots consisted different...
Aims: Evaluate whether mechanical damage and storage conditions affect the quality of ‘Markies’ potato for processing.
 Study Design: The experimental design was completely randomized, in scheme split-plots. plots were composed treatments with without subplots made up by evaluation times, 5 replicates, where unit 2 tubers.
 Place Duration Study: Tubers cultivar from producing region Perdizes, State Minas Gerais, planted June 2016 harvested October 2016.
 Methodology: tubers...
Atualmente, os serviços ambientais relativos aos sistemas agroflorestais (SAFs) estão fundamentados em aspectos qualitativos. Entretanto, para que ocorra a consolidação do pagamentos por tais serviços, diversos fatores condicionam SAFs necessitam ser caracterizados. Este estudo teve comoobjetivos analisar se o estoque de biomassa individual cafeeiros é afetado porSAFs caracterizados manejo e arranjos distintos dos arábica das grevíleas, além verificar haveria possibilidade ajuste equações...
The adequate storage of raw materials is fundamental to obtain a quality final product. objective this study was evaluate the effect different plastic packages on maintenance post-harvest ‘Agata’ potato tubers stored under refrigeration and room temperature. Two experiments were conducted, both with completely randomized design, arranged in 3 x 4 factorial scheme (three types – unpacked, polyvinyl chloride film PVC (21 cm 40 12 μm thick) bag (30 30 four evaluation times), three replicates...
ABSTRACT The objective of this study was to evaluate whether the inhibition gibberellin biosynthesis affects morphophysiological traits potted ornamental Capsicum baccatum and annuum growing under shade house conditions. Plants maintained in 2.7 L pots were arranged a completely randomized design 2x4 factorial consisting two pepper cultivars Chapéu-de-frade (C. baccatum) Vulcão annuum) four paclobutrazol (PBZ) concentrations (0, 25, 50, 75 mg L-1) with replicates. At 30, 45, 60 days after...
