The main environmental factors that play inevitable role in seasonal dimorphism are temperature and the length of the day.
Seasonal dimorphism is a process by which a species of organisms change their look and appearance, especially in their size and color following the change in the seasons. The main environmental factors inevitable in this type of dimorphism are temperature and the length of the day. In simple words,  the phenomenon with one species having differently looking images at different times of the year is called seasonal dimorphism.
Summer drought stress and winter cold stress in a specific area are the environmental triggers that stimulate these physical changes.
Seasonal dimorphism is considered from the anatomical viewpoint. Significant differences can be observed between winter and summer leaves obtained from the same individuals.
