Corn (Zea mays) is one of the most cultivated poaceae in the world with high agricultural potential. It is propagated through seeds, which sometimes remain stored until the sowing period. Among the various forms of storage, some aspects related to the environment and the type of material that constitutes the packaging may compromise the viability and vigor of these seeds. Therefore, the objective of this study ...
This study aimed to evaluate the effect of different concentrations of aqueous extract of purple nutsedge bulbs (Cyperus rotundus L.) compared to indole-3-butyric acid (AIB) on the germination and early growth of radish seedlings. Two experiments were conducted in both were used completely randomized design with four replications of 50 seeds for germination and 20 seeds for the length of the primary root. In th...
Grain production plays an important role in Brazilian agriculture. The main crops produced are soybeans and corn, followed by rice, beans and wheat. The State of Santa Catarina is responsible for much of the grain production in the southern region of the country. In this context, the use of quality seed ensures a better establishment of the crop and, consequently, greater productivity. Seed production and comme...
In Santa Catarina, the production of grains of maize shares space with the production of corn silage, which is used in cattle as forage for cattle food. In this sense, it is important to search for alternatives that minimize the loss of productivity, among them, reduce competition caused by weeds that affect the biomass accumulation. The objective was to evaluate the efficiency of Primóleo® (atrazine) and Calli...
La calidad fisiológica de la semilla podría afectar el rendimiento de granos de arroz. Las diferencias en la calidad fisiológica de las semillas pueden causar la reducción y desuniformidad de la emergencia en el campo, acarreando una diferencia en el crecimiento inicial de las plantas, y consecuentemente afectando el cultivo y su rendimiento. Se realizo un experimento con el objetivo de evaluar la distribución ...
As sementes de mamoeiro apresentam-se recobertas por membranas mucilaginosas denominadas de sarcotesta ou arilo e esclerotesta, que apresentam em sua constituição substâncias de potencial inibitório, responsáveis pelo controle da germinação. Objetiva-se com este trabalho determinar métodos favoráveis à remoção da sarcotesta em sementes de mamão, avaliando seus efeitos sobre a qualidade fisiológica das mesmas. O...
O teste de tetrazólio é um método rápido e eficaz para avaliação da qualidade fisiológica de sementes. O presente trabalho tem por objetivo estabelecer uma metodologia de pré-condicionamento de sementes de mamona para a avaliação da viabilidade e vigor pelo teste de tetrazólio. O trabalho foi realizado no Laboratório de Análise de Sementes e Mudas do Centro de Ciências e Tecnologia Agroalimentar da Universidade...
