Biochemical, physiological and growth changes in response to in vitro salinity ...
Oliveira, Leila Albuquerque Resende de; Cardoso, Milena Nascimento; Oliveira, Annie Carolina Araújo de; Machado, Caroline de AraújoAbiotic stresses in plants have aroused great research interest, unceasingly seeking for more productive cultivars under unfavorable cultivation conditions. Water deficiency and soil salinity are the most studied aspects, due to their strong impact on the growth and productivity of plants. The objective of this study was to evaluate accessions of different sugarcane species (Saccharum spp., S. robustum, S. offi...
Induction and growth curve of calli from leaf and nodal explants of genipap
de Oliveira, Annie Carolina Araújo; Machado, Caroline de Araújo; Resende de Oliveira, Leila Albuquerque; Padilha, Francine FerreiraThe aim of this study was to determine the effect of the auxin 2,4-D (2,4-dichlorophenoxyacetic) in calli formation from leaf and nodal segments of genipap and to characterize its growth curve. Explants obtained from shoots previously established from in vitro seedlings were used for calli induction. The experimental design was completely randomized in a 3x5x2 factorial with three accessions (NB, SA, SAL), five...
Physicochemical characterization of banana fruit by univariate and multivariate...
Lédo, Ana da Silva; Silva, Tatiana Nascimento; Martins, Carlos Roberto; Silva, Ana Veruska Cruz da; Lédo, Carlos Alberto da Silva; Amorim, Edson PeritoBreeding genotypes need to be characterized and evaluated in different soil and climatic conditions. There are few studies on association between characters evaluated and their contribution to banana genetic diversity, being essential to guide genetic breeding programs. This study aimed to evaluate the physicochemical characters of banana genotypes, to estimate associations between characters, to determine the ...

Melo, Jorge Luis Fonseca de; Mendonça, Vander; Silva, Ana Veruska Cruz da; Tavares, José CelesmárioO presente experimento foi conduzido na horta didática da Escola Superior de Agricultura de Mossoró- ESAM, com o objetivo de determinar o efeito de dois tamanhos de recipientes (15 cm x 23 cm e 23 cm x 35 cm), a embebição ou não das sementes em quatro períodos de permanência (50, 70, 90 e 110 dias após a semeadura) na formação de porta-enxerto de gravioleira. O delineamento experimental utilizado foi inteiramen...
COLAPSO INTERNO EM MANGA: NÍVEIS DE ADUBAÇÃO NITROGENADA E ARMAZENAMENTO REFRIG...
Romano, Daniel Henrique de M.; Mendoka, Vander; Silva, Ana Veruska Cruz da; Tavares, José Celesmário; Pio, RafaelAvaliou-se a incidência do colapso interno em mangas Tommy Atkins submetidas a dois níveis de adubação nitrogenada e ao armazenamento refrigerado. Para realização do trabalho foram colhidos frutos no estádio de vez em duas áreas, uma adubada com 3 kg de N/ha e outra com 7 kg de N/ha. Depois de colhidas, as mangas foram divididas em dois lotes de 14 caixas, com frutos variando em classificação de 6 a 12. Um lote...

DNA EXTRACTION METHODOLOGIES IN THE VINE AND RAPD ANALYSIS FOR AFLP1
Silva, Ana Veruska Cruz daGenus Vitis is of great economic importance worldwide and is taking this subject of several genetic studies. The objective of this study is to assess the quality of DNA extracted from young leaves of 19 grape cultivars, using six extraction methods - Saghay-Maroof, Soleman and Allard (1984); Shillito and Saul (1988); Doyle and Doyle (1991); Lodhi et al (1994).; This, Cuisset and Boursiquot (1997) and Kuo Line (...
