“…The advantage of this test is that it can be carried out in a shorter period of time. This occurrence is in agreement with Torres, Paiva, Almeida, Benedito, and Carvalho (2015) when reporting that the electrical conductivity test showed a highly significant correlation with the seedling emergence test in the field for Coriandrum sativum L., Portuguese, Super Verdão, Tabocas and Verdão.…”

Chia (Salvia hispanica L.) is an herbaceous plant that belongs to the Lamiaceae family. Seed vigor testing is an important component of quality control programs, and electrical conductivity test is a possible option in this process. The objective of this study was to identify a methodology of electrical conductivity test to stratify chia seed lots at vigor level according to the emergence of seedlings. Six lots of chia seeds were used in this study. The seeds were exposed to the following determinations: first germination count, germination, emergence speed index, emergence, aerial and root length, aerial and root dry matter, and electrical conductivity at 25, 50 and 75 mL during 1, 2, 4, 6, 8 and 24 hours of soaking in water. The electrical conductivity test in the combination of 25 seeds using 50 mL of water in 6-hour of soaking period, as well as the combination of 50 seeds using 50 mL of water for 24 hours of soaking, were efficient in the stratification of chia seeds in different levels of vigor.

“…In the electrical conductivity test, higher values were observed for seeds with radicle protrusion (1 and 3 mm). The germination process is followed by the release of sugars, amino acids and electrolytes in different amounts depending on the state of organization of the membrane system (Torres, Paiva, Almeida, Benedito, & Carvalho, 2015). In the present study, the rapid drying process applied to germinated millet seeds resulted in damage to the cell membranes and a subsequent rise in these solutes.…”

The aim of this study was to evaluate the physiological and biochemical changes related to the loss of desiccation tolerance in millet seeds. The points studied were determined according to the seed imbibition curve of the hybrid ADRF6010: control (0 h), 3 h, 1 and 3 mm of radicle. The seeds were dried on silica gel for 72 h at 20 °C, followed by pre-humidification at 25 °C for 24 h. The physiological quality was evaluated by the electrical conductivity and germination test, and the seed vigor through the first count and germination speed index. The experiment was performed in a completely randomized design and means were compared by the Scott-knott test at 5% probability. The enzymatic systems evaluated were: superoxide dismutase, catalase, peroxidase, and α-amylase, and the expression of heat-resistant proteins. The enzymatic activity was quantified through the software ImageJ®. Millet seeds lost desiccation tolerance when the radicle reaches 1 mm of length. According to the enzymatic standards, the enzymes peroxidase and α-amylase, as well as the activity of heat-resistant proteins are related to the loss of desiccation tolerance in millet seeds.

RESUMO - Estudos têm mostrado que o teste de germinação nem sempre revela diferenças na qualidade fisiológicaentre lotes de sementes, sendo necessária a complementação dos resultados com os testes de vigor, e, dentre eles,destaca-se o de condutividade elétrica, por ser considerado rápido, simples e confiável. Objetivou-se no presente trabalhoidentificar um trinômio constituído por volume, temperatura e tempo de embebição que possibilite o ranqueamentoentre lotes a partir do teste de condutividade elétrica. O experimento foi conduzido em delineamento inteiramentecasualizado, distribuído em parcelas subdivididas com três temperaturas (20, 25 e 30 °C) x quatro lotes (L1, L2, L3 eL4) x sete períodos de embebição (2, 4, 8, 12, 16, 20 e 24 horas) e embebidas em dois volumes de água (50 e 75 mL).A temperatura consistia na parcela, os tempos de embebição como as subparcelas e os lotes como sub-subparcelas,com quatro repetições por tratamento. O teste de condutividade elétrica mostra-se eficiente na diferenciação de lotes desementes sorgo sacarino. Para a condução do teste de condutividade elétrica, recomenda-se a embebição das sementesna temperatura de 30 °C por 12 horas utilizando o volume de 50 mL de água.Palavras-chave: Sorghum bicolor, germinação, potencial fisiológico, vigor.ELECTRICAL CONDUCTIVITY IN THE EVALUATION OF THEPHYSIOLOGICAL QUALITY OF SORGHUM SEEDSABSTRACT - Studies have shown that the germination test does not always reveal differences in the physiologicalquality between seed lots, and it is necessary to complement the results with the vigor tests, among which the electricalconductivity is outstanding, since it is considered fast, simple and trustworthy. The objective of this work was toidentify a trinomial consisting of volume, temperature and imbibition time that allows the ranking between batchesfrom the electrical conductivity test. The experiment was conducted in a completely randomized design, distributed insubdivided plots with three temperatures (20, 25 and 30 ºC) x four lots (L1, L2, L3 and L4) x seven periods of rainfall(2, 4, 8, 12, 16, 20 and 24 hours) and soaked in two volumes of water (50 and 75 ml). The temperature consisted of theplot, the imbibition times as the sub-plots and the lots as sub-sub-plots, with four replicates per treatment. The electricalconductivity test was efficient in the differentiation of lots of sorghum seeds. To perform the electrical conductivitytest it is recommended to soak the seeds at a temperature of 30 ºC for 12 hours using the volume of 50 mL of water.Keywords: Sorghum bicolor, germination, physiological potential, vigor.
