Inhibition of tuber sprouting in potato cultivars Asterix and Challenger by 1.4...
Mendonça Neto,Abelardo Barreto de; Pereira,Ariana Mota; Guimarães,Maria Eduarda da Silva; Gonçalves,Dreice Nascimento; Soares,Luciana GomesABSTRACT: The aim of this study was to verify the efficiency of 1,4-dimethylnapthalene in suppressing sprouting and the consequent maintenance of the quality of potato tubers of Asterix and Challenger cultivars, at different temperatures and storage regimes. Six treatments were tested, with and without 1.4-DNM, at temperatures of 8 ° C and 20 ° C. Assessments were made at 0, 45, 90, 135 and 180 days after appli...
Storage of markies cultivar potatoes for prossessing
Petrucci,Kharen Priscilla de Oliveira Salomão; Pereira,Ariana Mota; Moreira,Marialva Alvarenga; Cecon,Paulo Roberto; Finger,Fernando LuizABSTRACT The refrigerated induce the sweetening of the potato, which results in the dark color. The objective of this study was to determine the temperature and shelf life of Markies potato tubers under refrigerated storage for the processing of French fries. The levels of total soluble sugar (TSS), reducing sugars (RS), peroxidase (POD) and polyphenoloxidase (PPO) activity, color after frying and start of spro...
Allyl isothiocyanate as a fumigant in the cowpea and its effect on the physical...
Vilela,Ailyn de Oliveira; Faroni,Lêda Rita D’Antonino; Gomes,Jéssica Lino; Sousa,Adalberto Hipólito de; Cecon,Paulo RobertoABSTRACT The cowpea is subject to both quantitative and qualitative loss during storage due to attack by the insect pest Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae). There is a growing interest in controlling the pest using insecticides that result from the reactions of secondary metabolites produced by plants, due to their high efficiency, wide availability and selectivity for the target o...
Nonlinear quantile regression to describe the dry matter accumulation of garlic...
Puiatti,Guilherme Alves; Cecon,Paulo Roberto; Nascimento,Moysés; Nascimento,Ana Carolina Campana; Carneiro,Antônio Policarpo SouzaABSTRACT: The objective of this study was to adjust nonlinear quantile regression models for the study of dry matter accumulation in garlic plants over time, and to compare them to models fitted by the ordinary least squares method. The total dry matter of nine garlic accessions belonging to the Vegetable Germplasm Bank of Universidade Federal de Viçosa (BGH/UFV) was measured in four stages (60, 90, 120 and 150...
Pre-harvest desiccation in biomass sorghum with herbicides
Barros,Angélica Fátima de; Pimentel,Leonardo Duarte; Freitas,Francisco Cláudio Lopes de; Cecon,Paulo Roberto; Tomaz,Adriano CirinoABSTRACT The purpose of this study was to assess the effect of different herbicide treatments on moisture removal and calorific power of biomass sorghum for co-generation of electric energy through burning. The experiment was conducted in randomized complete block design with four replicates per treatment and a 6x4 factorial scheme (six herbicide treatments x four intervals between spraying and harvesting). The...
Chemical composition in soybean silages with inoculant and molasses
Rosa,Lilian Oliveira; Pereira,Odilon Gomes; Ribeiro,Karina Guimarães; Valadares Filho,Sebastião de Campos; Cecon,Paulo RobertoAbstract Chemical composition was assessed in soybean silages without any additive (control), with a microbial inoculant (I), with I + molasses (I+M), and with molasses only (M). Soybean plants were harvested at the reproductive 6 (R6) stage and ensiled in 2 kg-capacity PVC laboratory silos. The SIL ALL C4 inoculant produced by Alltech Brazil was used in combination with or without 2.5% molasses added to the na...
Leaf and Stem Anatomy of Cherry Tomato Under Calcium and Magnesium Deficiencies
Martinez,Herminia Emilia Prieto; Maia,Janini Tatiane Lima Souza; Ventrela,Marília Contin; Milagres,Carla do Carmo; Cecon,Paulo RobertoAbstract Studies evaluating the influence of nutrients on plant anatomy are very important because nutritional deficiencies can alter the thickness and shape of certain tissues, compromising their functionality what can explain the reduction of productivity. The aim of this study was to characterize the anatomical changes in cherry tomato plants subjected to calcium (Ca) and magnesium (Mg) deficiencies. The exp...
Estimation of optimum experimental plot size for taro culture
Silva,Willerson Custódio da; Puiatti,Mário; Cecon,Paulo Roberto; Macedo,Leandro Roberto de; Sediyama,TocioABSTRACT: Taro is a tropical tuberous vegetable that produces cormels of high nutritional and energetic value. In recent years, its cultivation has expanded, creating the need for more research. However, the experimental plot size interferes directly with the precision of the experiment.Literature describes several methods for establishing the optimum experimental plot size. The objective of the current researc...
Biogenic, sedimentary, and metamorphic limestone: a comparative characterizatio...
Cazotti,Maria Maiara; Costa,Liovando Marciano da; Cecon,Paulo RobertoABSTRACT Liming acid soils is fundamental for agricultural activity such as the study and characterization of alternative liming material. The objective of this study was to characterize biological, sedimentary, and metamorphic limestones. The following limestones were studied: biogenic (BL), sedimentary (SL), commercial (CL), and marble (ML). This study evaluated total relative neutralizing power (TRNP), chemi...
Development and evaluation of a remotely controlled and monitored self-propelle...
Penido,Édilus de Carvalho Castro; Teixeira,Mauri Martins; Fernandes,Haroldo Carlos; Monteiro,Paulo Barros; Cecon,Paulo RobertoABSTRACT The tomato is one of the main crops in Brazil. In large-scale cultivation, pesticides are applied to the plant to prevent the direct or indirect action of animal or vegetable life, aiming at higher productivity and better quality fruit. However, the products, if used incorrectly, may affect the health of workers involved in the activity. A prototype of a self-propelled sprayer, remotely controlled and ...
