Effects of paclobutrazol on ethylene sensitivity of potted pepper cultivars
Nascimento, Mayana Ferreira; Araújo, Fernanda Ferreira de; Santos, Rusthon Magno Cortez dos; Silva Neto, João José da; Bruckner, Claudio HorstExposure to ethylene of ornamental plants is one of the factors that affect the life cycle post-production of these plants. The aim of this work was to evaluate the effects of paclobutrazol (PBZ) on the ethylene related responses of ten pepper cultivars of the genus Capsicum and one Solanum by simulating transport and commercialization. The cultivars were treated with PBZ at concentrations of 0, 5, 10 and 20 mg...
An approach of using different curing temperature based on potato cv. Innovator...
Pereira, Ariana Mota; Picoli, Edgard Augusto de Toledo; Petrucci , Kharen Priscilla de Oliveira Salomão; Gomes, Mateus de PaulaExcoriation damage is among the major causes of postharvest potato losses. Curing is known to increase the resistance of tubers to excoriation injury, with the temperature influencing the traumatic phellogen and periderm regeneration, as well as tuber processing quality. This study aimed to evaluate the effects of excoriation procedure and curing temperature on the industrial quality, histological characteristi...
Oxidative stress, protein metabolism, and physiological potential of soybean se...
Pinheiro, Daniel Teixeira; Dias, Denise Cunha Fernandes dos Santos; Silva, Laércio Junio da; Martins, Maycon Silva; Finger, Fernando LuizWeathering deterioration affects seed quality, especially in areas with excessive rainfall. This study aimed to evaluate the oxidative stress, physiological quality, and protein metabolism of seeds of different soybean cultivars under weathering deterioration at the pre-harvest phase. Six soybean cultivars (BMX Apolo, DM 6563, NS 5959, NA 5909, BMX Potência, and TMG 1175) were subjected to simulated rainfall at...
Fruit size, mineral composition and quality of trickle-irrigated tomatoes as af...
Fontes, Paulo Cezar Rezende; Sampaio, Regynaldo Arruda; Finger, Fernando LuizPara determinar o efeito da fertirrigação com K sobre o tamanho, a composição mineral e a qualidade dos frutos do tomateiro, foi conduzido um experimento com aplicação de seis doses de K, na forma de KCl, correspondendo a 0, 48,4, 118,6, 188,8, 259,0 e 399,4 kg ha-1, com quatro repetições, distribuídas no delineamento experimental em blocos casualizados. Foram observadas respostas quadráticas das produções das ...
Growth and yield of coffee plants in agroforestry and monoculture systems in Mi...
Garcia, Silvana Lages Ribeiro; Finger, Fernando Luiz; Martinez, Hermínia Emília Prieto; Freitas, Gilberto Bernardo de; Santos, Ricardo Henrique SilvaThis research compared coffee plants (Coffea arabica L.) grown in an agroforestry and monoculture systems. Data were collected during two years, on vegetative growth, reproductive development, nutritional status and yield of coffee, besides monitoring air temperature and the tree growth. All trees in agroforestry system increased in growth, resulting in a reduction in the magnitude of the diurnal temperature va...
Soluções conservantes prolongam a vida de vaso de inflorescências cortadas de b...
Vieira, Luciana Marques; Mendes, Teresa Drummond Correia; Finger, Fernando Luiz; Barbosa, José GeraldoO objetivo deste trabalho foi avaliar o efeito de soluções de vaso na longevidade pós-colheita de inflorescências de boca- de-leão. Hastes de boca-de-leão (‘Potomac White’), colhidas com seis a sete flores abertas na inflorescência, foram condicionadas em: (1) água desionizada a 20oC (controle); (2) água quente a 43°C, por uma hora, seguida de água desionizada (20oC) como solução de vaso; (3) solução de Flower ...
Action of abscisic and gibberellic acids on senescence of cut gladiolus flowers
Costa, Lucas Cavalcante da; Araujo, Fernanda Ferreira de; Lima, Paula Cristina Carvalho; Pereira, Ariana Mota; Finger, Fernando LuizThe gladiolus flower is classified as insensitive to ethylene. Thus, the signals that initiate senescence are poorly understood. This study evaluated the role of abscisic and gibberellic acids on postharvest senescence of 3 cultivars of cut gladiolus flowers (Gladiolus grandiflora Hort.). Stalks were harvested and placed in test tube containing 100 mL distilled water or an aqueous solution of abscisic acid (100...
Divergência genética entre acessos de taro
Pereira, Francisco Hevilásio F.; Puiatti, Mário; Miranda, Glauco V.; Silva, Derly José H. da; Finger, Fernando LuizAvaliou-se a variabilidade existente entre 36 acessos de taro do Banco de Germoplasma de Hortaliças da Universidade Federal de Viçosa em componentes do rendimento, visando a identificação de acessos produtivos e divergentes para serem utilizados em programas de melhoramento. O experimento foi conduzido na horta de pesquisas da UFV, de 19/09/2000 a 13/06/2001. Utilizou-se o delineamento experimental blocos casua...
Characterization of symptoms of senescence and chilling injury on inflorescence...
Finger, Fernando Luiz; Costa, Andreza S.; Nogueira, Luis Carlos; Santos, Venézio F. dos; Camara, Terezinha Rangel; Loges, Vivian; Willadino, LiliaInadequate temperatures during the shipping and commercialization of cut tropical flowers may accelerate the senescence process and cause chilling injury, leading to symptoms that have not yet been described for Heliconia bihai. The aim of the present study was to evaluate physiological responses in cut inflorescences of H. bihai cv. Lobster Claw (LC) and cv. Halloween (HW) as well as symptoms of senescence and...
Agro-climatic zoning to banana-growing in the mesoregion of Vale do Rio Doce
Dias, Luiz Antônio dos Santos; Coelho, Geovália Oliveira; Finger, Fernando LuizO objetivo desta pesquisa foi identificar, por meio de zoneamento, a aptidão edafoclimática da mesorregião Vale do Rio Doce para a produção comercial de banana. Os fatores utilizados no zoneamento agroclimático foram temperatura, altitude, precipitação, deficiência hídrica e tipo de solo. As informações sobre as condições térmicas foram obtidas do Instituto Nacional de Meteorologia e por meio de estimativas de ...
