CASTILHO, Itala Menegon et al. Electrical conductivity test in evaluating the physiological potential of chickpeas seeds. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.3, pp.101-110. ISSN 0871-018X.  https://doi.org/10.19084/rca.17449.

The vigor tests were developed to compensate for deficiencies in the germination test. This study aimed to evaluate the use of electrical conductivity in the physiological potential of chickpeas seeds. Four seed lots of cultivar ‘BRS Aleppo, were tested for germination, first count germination, seedling emergence, speed of emergence and accelerated aging. For the electrical conductivity were studied variations in the volume of water (50 and 75mL), temperature (25 and 30^oC), number of seeds (25 and 50) and imbibed (1, 2, 4, 6, 12, 18 and 24 hours). The electrical conductivity test was efficient for the chickpeas seeds, and the soaking time can be reduced to four hours, but using 50 seeds failed to differentiate between batches. The volume of 25mL and 30°C was the most favorable condition for the consistent ordering of the lots on the force. The best conditions for the electrical conductivity in chickpeas seed are the use of 25 seeds in 50mL of water for four hours at 30^oC.
