- Abstract
The tests of germination and vigour are essential components of the quality control process of seed producers. Therefore, the aim of this research was to study the methodology of the test of electrical conductivity, verifying its efficiency in identifying different levels of vigour in batches of coriander seed. To do this, four cultivars were used (Português, Super Verdão, Tabocas and Verdão), each represented by four batches of seed, which were initially subjected to evaluations of moisture content, germination, germination first count and seedling emergence. The test of electrical conductivity was carried out on 25 to 50 seeds soaked in 50 and 75 mL of distilled water at 25 °C for 2, 8 and 24 hours. The test of electrical conductivity is efficient to evaluate the physiological potential of coriander seeds when carried out with 50 seeds immersed in 50 mL of distilled water at 25 °C, after soaking for two hours.
