Wild apple trees usually reach age 10 to 12 in this period. [7] The number of fruits increase significantly as prominent secondary growth and branching take place. [7] Period III involves more growth and fruit bearing. [7] Wild apple trees enter regular fruiting and reach maximum fruit bearing in this period, and usually reach age 25 to 30. [7]
Plant morphology is the field in botany that studies the diversity in forms, with the naked eye or slight optical magnification. This is opposed to plant anatomy (see Category:Plant anatomy) that needs to cut into plants to be able to study its subject, usually with a microscope.
