Why do you think the seeds need to be exposed to a moist cold environment
before they will germinate? (Hint: Think about fruit trees and their seeds as
they evolved in the natural world.)
What will be an ideal response?
The moist cold temperatures simulate the environmental conditions of winter. Seeds
that are able to overwinter before germinating may not have to compete with as
many members of the parental generation. Parent plants that die in winter make
space available for new seedlings in the spring.
