If a farmer pre-chills seeds of *Echinacea purpurea* before planting, which consequence follows?

💡 Explanation

Seed stratification involves pre-chilling seeds to break dormancy because this temperature exposure triggers biochemical changes that overcome germination inhibition; therefore, stratification results in dormancy breaking, rather than enforcing it, and has no direct effect on abscisic acid production or storage protein synthesis.
