O presente trabalho teve por objetivo analisar a metodologia do teste de envelhecimento acelerado, bem como verificar a possibilidade do uso de Cloreto de Sódio (NaCl) como opção para controle da absorção de água pelas sementes durante a realização do teste. Foram utilizados cinco lotes de sementes, submetidos aos testes de germinação (G), emergência de plântulas (EP), índice de velocidade de emergência (IVE) e...
O feijão-miúdo (Vigna unguiculata) apresenta multiplicidade de usos, que o torna boa opção para os agricultores, podendo ser utilizado além de recuperador de solos, como forragem verde, na alimentação animal e destaque na consorciação com gramíneas de alto potencial de produção. Objetivou-se adequar o teste de condutividade elétrica para avaliação do vigor de lotes de sementes de feijão miúdo. Foram utilizados ...
Saccharin sorghum is cultivated from seeds, requiring adequate production, harvesting and drying techniques to ensure the availability of quality seed and, therefore. The objective was to evaluate the initial quality by studying a more adequate methodology of the accelerated aging test for the evaluation of the physiological potential of sorghum seeds. The research was conducted in the Laboratory of Seed Analys...
Micronutrients, such as zinc, are important for the metabolic activities that can benefit germination and seed vigor because many soils are deficient in this micronutrient. The objective of this study was to evaluate the influence of coating oat seeds with zinc on the physiological quality and yield of the seeds produced. The experimental design was completely randomized, with a 2 x 5 factorial arrangement of t...
Physiological aspects of toxicity of organic acids to oat seeds. For the cultivation of oats (Avena sativa L.) as an alternative which is economically viable in fl ooded soils, it is necessary to use cultivars that are tolerant to the main organic acids produced by the decomposition of the organic matter generated when cultivatingareas by direct seeding. The objective of this work was to determine the concentra...
