Soaking and drying have proven to be effective strategies for fruit tree seed stratification when applied as separate treatments. This study evaluated the effect of these treatments on pericarp cracking and germination of hawthorn seeds (Crataegus mexicana Moc. & Sessé ex DC.) seeds on pericarp cracking and germination. A 2³ factorial experimental design was used to analyze the factors: soaking time (72 h and 144 h), drying temperature (32 °C and 40 °C), and drying time (1 h and 2 h). The evaluated variables were carpel cracking (mm) and seed germination (%). A drying temperature of 40 °C resulted in the highest carpel cracking (4.66 mm) and the highest germination (17.33 %). A positive correlation was found between cracking and germination (R2 = 0.60, p = 0.0019).
