Growth retardants in wheat and its effect in physiological quality of seeds
Souza, Leandro Torres de; Espíndula, Marcelo Curitiba; Rocha, Valterley Soares; Dias, Denise Cunha Fernandes dos Santos; Souza, Moacil Alves deO acamamento de plantas na cultura do trigo tem sido controlado com o uso de redutores de crescimento. No entanto, há carência de informações sobre o efeito desses produtos na qualidade fisiológica de sementes. O objetivo deste estudo foi avaliar a qualidade fisiológica das sementes de trigo obtidas sob efeito de doses e épocas de aplicação de três redutores de crescimento. O experimento, conduzido em Viçosa, M...
Concentration and accumulation of micronutrients in robust coffee
Dubberstein, Danielly; Partelli, Fábio Luiz; Espíndula, Marcelo Curitiba; Dias, Jairo Rafael MachadoKnowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients in the leaves and fruits of Coffea canephora. The experiment was managed in crops propagated for 2.5 years in a split-plot-in-time scheme in which the main plots consisted of fertilized a...
Quality evaluation of Coffea canephora ‘Apoatã’ seeds for rootstock production
Espíndula, Marcelo Curitiba; Botelho, Frederico José Evangelista; Clemente, Aline da Consolação Sampaio; Teixeira, Alexsandro LaraCoffea canephora ‘Apoatã’ seeds are used for the formation of rootstocks for grafting of C. arabica seedlings. The quality of seeds and the individualization of used genotypes are prevalent factors for the formation of vigorous rootstocks that will enhance the formation of quality seedlings. The aim of the present study was to characterize and evaluate the seed quality of C. canephora ‘Apoatã’ genotypes for pot...
