The objective of this study was to determine seed moisture content that can reduce the proconditioning period (imbibition time) before the staining process in the tetrazolium test for soybean seed. Two experiments were conducted: experiment I-two soybean seed lots of the cultivars BR-30 and BR-16 were submitted the six periods of imbibition under four temperatures; experiment II-three seed lots of fiscalized soybean seed of the cultivars Davis, BR-29 and BR-24 were submitted to seven periods of imbibition at 25.C In a general manner, it was observed that the seeds of the cultivars BR-30 and BR-16 reached 37% seed moisture content after 10h/40.C the preconditioning period. This moisture content, resulted in adequate staining patterns for determining vigor [TZ (1-3)] and viability [TZ (1-5)] for tetrazolium test in soybean seed. |
