Metodologia alternativa para o teste de condutividade elétrica na determinação do vigor de sementes de soja

Abstract

Brazil is a large food producer, with emphasis on commodities. Soy is the main crop cultivated in Brazil, being the leader in its segment, reaching a planted area of 43,529.9 thousand hectares, with productivity of 151,419.4 thousand tons (Conab 2023). Since production is growing, the use of quality seeds to sow crops is indisputable. To measure the quality of seeds, tests are used to evaluate characteristics: physical, physiological, genetic and health. Therefore, the objective of this work is to seek an alternative methodology in electrical conductivity testing, determining the best interaction between the seed imbibition time, seeking to optimize the work, facilitating monitoring and helping in decision making. There is a tendency for 4pm and 8pm to present results correlated to the currently accepted methodology (24 hours). Further research related to the topic is recommended to define an alternative methodology for electrical conductivity testing.
