The desiccation tolerance presented by orthodox species is a characteristic that allows the loss of water keeping the seed viable. However, the reduction of the moisture content by drying, has a critical limit, and a loss beyond this limit results in a reduction in the physiological quality of the seeds, TBIO Sossego cultivar. The objective of this study was to evaluate the physiological changes resulting from the reduction of moisture percentage in the artificial drying process of wheat seeds. The seeds used were of the cultivar TBIO Sossego with initial water content of 14.7%. The seeds were dried at 40 ± 2 °C until reaching 12, 10 and 8% moisture. The evaluated variables were germination, seedling length, electrical conductivity, field emergence, shoot length and root length. Drying of wheat seeds can be performed up to 8% moisture without affecting the physiological quality of the seeds.
