Determination of pre-wetting procedure of coriander seeds for tetrazolium test

Abstract

ABSTRACT Searching to determine the quality of seeds using rapid and effective tests, the aim of this study was to evaluate the influence of pre-wetting procedures on determining the viability of coriander seeds by the tetrazolium test. Ten seed batches of coriander were used. The experiment was carried out in a completely randomized design, in a 10x2 factorial scheme (10 batches x moistening and soaking in water) with four replications. Seeds of each batch were previously evaluated through water content, germination with and without fungicide treatment, and the emergence of seedlings in the sand. The seeds were pre-wetted in two ways: rolls of filter paper and directly in water for 16 hours at 20oC temperature. Despite the numerical difference between the pre-wetting forms, these differences were not significant. Thus, we considered that both ways of pre-wetting are appropriate. Coriander seeds were influenced by pre-wetting, resulting in a quick availability evaluation through the tetrazolium test. Thus, pre-wetting can be carried out by water immersion or paper through longitudinal cutting.
