Abstract

Distinctly different growth phases in apple occurred during the course of development from seed to tree. The juvenile condition was recognized by the thinner leaves with much less pubescence. Anthocyanin production was more abundant in juvenile shoots. In some species of apple, the shape of the leaf changed from an entire to a lobed form with the approach of maturity.
