Seed dormancy mechanisms in plants

Seed dormancy is a survival strategy that prevents germination under unfavorable conditions, enhancing plant species' persistence. Dormancy mechanisms vary, influenced by hormonal signals (like abscisic acid and gibberellins), environmental factors, and seed coat properties. Physical dormancy involves a hard seed coat that restricts water absorption, while physiological dormancy depends on internal factors like hormone balance. Temperature, light, and moisture can break dormancy, signaling readiness for germination. Seed dormancy is crucial in agriculture, as manipulating these processes allows better control over germination timing, crop cycles, and adaptation to changing climates, ultimately optimizing food production.
