The growth cycle of M. sieversii could be divided into several stages from germination to developing fruit bearing trees, and to the death of aged trees. [7] Period I starts from seed germination to the development of vegetative tree parts, and to the first round of fruiting. [7] A typical apple tree reaches age 6 to 8 in this period.

Annona squamosa is a small, well-branched tree or shrub [7] from the family Annonaceae that bears edible fruits called sugar apples or sweetsops. [8] It tolerates a tropical lowland climate better than its relatives Annona reticulata and Annona cherimola [6] (whose fruits often share the same name) [3] helping make it the most widely cultivated of these species.
