Living habits:

Apple is a deciduous tree with strong polarity, usually vigorous growth and high crown. The height of the tree can reach 15 meters, and it is about 3 ~ 5 meters under cultivation conditions.

Like light, like slightly acidic to neutral soil. It is most suitable for sandy soil with deep soil layer, rich organic matter and good ventilation and drainage.

Apple trees begin to bear fruit 2 ~ 3 years after planting. Under management conditions, the economic life is 15 ~ 50 years, while the soil is barren and the extensive management is only 20 ~ 30 years. Due to the combined effect of apical dominance and bud heterogeneity, apples usually have strong dryness and obvious stratification. Due to the differences in germination and branching ability among varieties, the obvious stratification degree is also different.

Apple buds are divided into leaf buds and flower buds according to their properties. Leaf buds are triangular, long and curved, and grow into branches after spreading leaves, which are called new shoots or vegetative branches. Branches can be divided into long branches, common branches, slender branches and leafy branches according to their growth. The flower buds of apples are mixed buds. Axillary flower buds are buds formed in the axils of leaves of branches of the same year, and those that can blossom and bear fruit in the next year are called axillary flower buds.

The flower bud differentiation of most apple varieties began in early June and ended before winter. The whole process is divided into three stages: physiological differentiation, morphological differentiation and sexual cell maturation. The flower buds are mixed buds and the inflorescences are corymbose cymes. 5-7 flowers per inflorescence.
