Suitability of tetrazolium test for Tamarindus indica L. seeds
Cordeiro, Luciana Nunes; Bruno, Riselane de Lucena Alcântara; Lima, Lucas Kennedy Silva; Andrade, Albericio Pereira de; Belarmino, Karialane da SilvaSeed quality is routinely assessed by direct tests, e.g, the germination test, or indirect tests like the tetrazolium test, which has shoown to be promising in the determine viability and vigor, allowing the diagnosis of the main problems that may affect seed quality, such as mechanic damages, field deterioration and storage. In this respect, this study was conducted to develop a tetrazolium test protocol to ev...
Vigor tests in seeds creole of Phaseolus lunatus L.
Nascimento, Maria das Graças Rodrigues do; Silva, Maria Lúcia Maurício da; Alves, Edna Ursulino; Rodrigues, Caroline Marques; Silva, Maria Joelma daSeeds with a good physiological quality are essential to high productivity. However, for some seeds, Phaseolus lunatus L., the viability and vigor analyze show deficiency in quality. This work aimed to evaluate the physiological quality of Phaseolus lunatus L. seeds using several vigor tests. The study was realized at the Laboratory of Seed Analysis of the Agricultural Sciences Center of the Federal University ...

Physiological potential of Phaseolus lunatus L. seeds subjected to water stress...
Nascimento, Maria das Graças Rodrigues; Silva, Maria Lúcia Maurício da; Alves, Edna Ursulino; Rodrigues, Caroline MarquesGermination is negatively influenced by water scarcity and by temperatures above or below the optimal range of the species, so it is necessary to know the critical point of absorption for the species or cultivar. The objective of this work was to evaluate the effect of water stress, simulated by solutions of polyethylene glycol 6000 (PEG 6000) at different temperatures, on the germination and vigor of seeds of ...
Temperatures and substrates for germination and vigor of Erythroxylum pauferren...
Ribeiro, João Everthon da Silva; Leite, Arliston Pereira; Nóbrega, Jackson Silva; Alves, Edna Ursulino; Bruno, Riselane de Lucena AlcântaraErythroxylum pauferrense is an endemic understory plant species of the Northeast Region of Brazil. The species is of great importance to the region and so ecophysiological studies are needed for its preservation. The objective of the present study was to determine the best substrates and temperatures for testing germination and seed vigor of E. pauferrense. An experiment was performed comprising a completely ra...
