Quizplus · Accepted Answer

Abscisic acid (ABA) is a hormone that inhibits seed germination and promotes seed dormancy. ABA levels are highest in mature seeds and prevent them from germinating immediately after being released in the fall. As winter approaches, ABA levels may decrease, allowing the seed to germinate in the spring when conditions are favorable.
