Última Germination and seedling growth of Enterolobium contortisiliquum as a function of seed weight and temperature and light conditions Agrociencia Lessa,B. França da Trindade; de Almeida,J. Paulo Nobre; Pinheiro,Charles Lobo; Gomes,Fernanda Melo; Medeiros-Filho,Sebastião. Studies of germination behavior and seedling establishment contribute to the development of appropriate methods of forest species management. The aim of this study was to investigate germination and seedling growth of tamboril (Enterolobium contorsiliquum (Vell.) Morong), taking into account environmental factors and seed weight. Seeds were separated into three weight classes (light, medium and heavy), to determine the moisture content percentage and thousand-seed weight per class. Seeds from each class were then tested for germination. The experimental design was completely randomized with a 2x3x4 factorial arrangement of treatments: two light conditions (presence and absence), three weight classes (Light < 0.7 g; Medium 0.7 to 0.8 g; Heavy &gt;...

Del Carmen; Ortiz-Cereceres,Joaquín. Se evaluó la velocidad de germinación y el crecimiento de plántulas de maíz provenientes de semilla de dos diferentes tamaños para determinarlas diferencias en la producción de biomasa durante la etapa vegetativa y estimar los efectos de una condición diferente de disponibilidad de humedad sobre el estatus fisiológico de la plántula. Una mayor cantidad de biomasa en el endospermo y en el embrión de las semillas permitió una mayor disponibilidad de reservas durante la etapa posterior a la germinación y anterior a la emergencia, dando como resultado un mayor vigor inicial en las plántulas evaluadas, y en consecuencia una mayor acumulación de biomasa, tanto radical como aérea, durante la etapa vegetativa. La presencia de una restricción de humedad durante la... Tipo: Info:eu-repo/semantics/article Palavras-chave: Maize; Seed size; Seedling vigor; Biomass; Drought; Gas exchange. Ano: 2004 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-56572004000100030 Vigor-S, a new system for evaluating the physiological potential of maize seeds Scientia Agricola Castan,Danielle Otte Carrara; Gomes-Junior,Francisco Guilhien; Marcos-Filho,Julio. ABSTRACT: The refinement of vigor tests and the possibility of utilizing computer resources for the effective evaluation of the seed physiological potential have attracted considerable interest from research and seed technologists. The aim of this study was to evaluate the physiological potential of maize seeds using the newly-created Automated Analysis of Seed Vigor System (Vigor-S) compared with other recommended seed vigor tests; two maize hybrids were used, each represented by seven seed lots. Germination and vigor (cold test, saturated salt accelerated aging, and field seedling emergence) evaluations were conducted. For the evaluation of seed vigor with the use of seedling image analysis resources, two systems were compared: the Seed Vigor Imaging...

Ano: 2018 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-90162018000200167 Swingle citrumelo seed vigor and storability associated with fruit maturity classes based on RGB parameters Scientia Agricola Gomes-Junior,Francisco Guilhien; Arruda,Natália; Marcos-Filho,Julio. ABSTRACT: Citrus seeds normally have low storability. Identifying an optimal fruit harvest time for production of high vigor seeds is important for nurseries; however, identifying this stage for Swingle citrumelo fruits has been based only on visual color examination, and research related to this parameter has been inconsistent. The main objective of this study was to evaluate a red-green-blue (RGB) color measurement system for successful identification of Swingle citrumelo fruits possessing seeds with maximum physiological potential and storability. Fruits were harvested at three ripening stages identified as green (G), greenish-yellow (GY), and yellow (Y) pericarp, photographed, and the images processed using ImageJ software. Data were expressed as the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Image analysis; Computer vision; Fruit maturation; Citrus rootstock; Seedling vigor.
