Gomes Ferreira, Débora da Rocha; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; Ralph, Lidiana Nayara; Silva, Júlio Cesar de AlmeidaH. impetiginosus belongs to the Bignoniaceae family; it has a great potential for economic exploitation and can be used in landscaping of urban areas, reforestation, recovery of degraded areas, and folk medicine. The experiment was carried out to evaluate the effect of light and temperature regimes on the germination and vigor of Handroanthus impetiginosus seeds at the Seed Analysis Laboratory of UFRPE/UAG. The...
Chemical-bromatological quality and productivity of peanut genotypes (Arachis h...
Barbosa, Jorge Marcos Peniche; Viana, Jeandson Silva; Ferreira, Débora Teresa da Rocha Gomes; Santos, Alessandro dos; Gonçalves, Edilma PereiraPeanuts (Arachis hipogaea L.) have a great potential for grain production for feed and forage production, being an alternative for producers, as it grows a double product. Grains have excellent quality and contain a greater amount of protein with which to feed the herd. The present study is a cut-off effect study with an application of Stimulate® phytostimulant to determine grain quality and peanut fodder genot...
EFICIÊNCIA DA APLICAÇÃO DE NUTRIENTES VIA SEMENTE E FOLIAR NA CULTURA DO AMENDOIM
Silva, Raphaela Maceió; Viana, Jeandson Silva; Gonçalves, Edilma Pereira; Moraes, Guilherme Souza deO adequado suprimento de nutrientes é essencial para promover o crescimento e desenvolvimento das plantas e assegurar elevados níveis de produtividade das culturas. Este estudo teve como objetivo avaliar a eficiência da aplicação de cálcio (Ca), boro (B), cobalto (Co) e molibdênio (Mo) nas sementes associado à aplicação foliar de Ca + B em diferentes épocas na cultura do amendoim. O ensaio constituiu das seguin...
Agronomic performance of sesame (Sesamum indicum L.) genotypes under phytostimu...
Viana, Jeandson Silva; Costa, Djayran Sobral; Lima, Juliana Joice Pereira; Gonçalves, Edilma Pereira; Arriel, Nair Helena CastroSesame (Sesamum indicum L.) is one of the oldest cultivated plant species and become an important alternative to reduce food deficiency in low income populations. Growth regulators influence protein metabolism and may increase the rate of enzyme synthesis involved in the process of seed germination, rooting, flowering, and fruiting of plants. This study aimed to evaluate the agronomic performance of sesame geno...
Effect of temperature and substrate on germination of Peltophorum dubium (Spren...
Alves, Edna Ursulino; Guedes, Roberta Sales; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; Santos, Sueli da Silva; Moura, Mácio Faria dePeltophorum dubium (Spreng.) Taub. is a species belonging to the family Fabaceae, and is known popularly as golden shower tree. Its wood has multiple uses in reforestation programs and as an ornamental tree, and is also considered an endangered species, requiring studies that assist in its preservation. The present work was conducted with the objective of determine the ideal substrate type and temperature to pe...
Emergence and vigor of Amburana cearensis (Allemão) A.C. Smith seedling in func...
Guedes, Roberta Sales; Alves, Edna Ursulino; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; Moura, Macio Farias de; Costa, Edilson Guedes daAmburana cearensis (Allemão) A.C. Smith is a Fabaceae, popularly known as cumaru or cherry tree. This species is native of Northeast Brazilian and has its qualities for industry of wood and as medicinal plant. It has being explored progressively, and now it is striped as threatened species of extinction. So, studies that help in its preservation are important. With the objective of verifying the effect of the p...
Physiological quality of Amburana cearensis (Allemão) A.C. Smith seeds stored
Guedes, Roberta Sales; Alves, Edna Ursulino; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; França, Pablo Radamés Cabral de; Santos, Sueli da SilvaThis work aimed to determine the best conditions and storage periods adapted to conservation of seed vigor for Amburana cearensis (Allemão) A.C. Smith. The experiment was conducted at the Laboratory of Analysis of Seeds (CCA/UFPB), using an entirely randomized design. The treatments consisted of A. cearensis seeds packaged in: paper Kraft bags, bags of cotton and foil aluminum, two storage conditions: room temp...
Precocity of soybean cultivars on cultivation systems with corn in Areia, Paraí...
Viana, Jeandson Silva; Bruno, Riselane Lucena Alcantara; Mendonça, José Lindorico; Gonçalves, Edilma Pereira; Alves, Edna UrsulinoThe objective of this work was to evaluate the effect of cultivation systems, associated or not with an inoculant, in the precocity of soybean cultivars at the green grain growth stage. The research was led in field conditions, in CCA/UFPB, Areia-PB with an experimental design in randomized blocks, in sub-subdivided plots (3 x 2 x 2), three cultivars (Pati, JLM 004 and Pirarara), with and without inoculation an...
Physiological response of Erythrina velutina Willd. seeds to accelerated aging
Guedes, Roberta Sales; Alves, Edna Ursulino; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; Bruno, Riselane de Lucena AlcântaraSeed vigor testing is an important component of quality control programs, and accelerated aging is a possible option in this process. This study was conducted to investigate procedures to assess seed vigor by the accelerated aging test in forest seeds of Erythrina velutina. The experiment was realized at laboratory conditions at Universidade Federal da Paraíba, in Areia – PB, Brazil Northeast. T...
Seedling length test in the evaluation of the physiological quality of Erythrin...
Guedes, Roberta Sales; Alves, Edna Ursulino; Gonçalves, Edilma Pereira; Viana, Jeandson Silva; Medeiros, Matheus Serrano de; Lima, Cosmo Rufino deAmongst the vigor tests, the test of length of seedlings has potential to give complementary informations to the germination test and makes possible to estimate the potential of emergence of seedlings in the field. The aim of this research work was to inquire the possibility of use of the length of seedlings test as a method of vigor to classify lots of seeds of Erythrina velutina. The physiological quality of ...
