Question

Quizplus · Accepted Answer

Abscisic acid is a plant hormone that inhibits seed germination and promotes dormancy, so it does not serve to break dormancy and initiate seed germination. The other choices, scarification by abrasion or fire and exposure to water, physically remove or weaken the seed coat, allowing water to penetrate and trigger germination. Growth promoters, such as gibberellin, stimulate seed germination and are necessary for successful seedling growth.
