Question

Quizplus · Accepted Answer

Seeds from plants native to a place with hot summers and cold winters would probably need exposure to cold to break their dormancy and promote their germination. This process is called cold stratification, and it simulates the natural conditions that the seeds would experience during winter. Cold stratification can be achieved by storing the seeds in a moist substrate at a temperature between 32-41°F for a period of several weeks to several months, depending on the species. This treatment can help to soften the seed coat, initiate biochemical changes, and synchronize the germination of the seeds once they are planted in the spring.
