Peach

The peach tree leaves are deciduous, essential for the plant's winter dormancy cycle, which is crucial for fruit production. Observing the leaves is important for diagnosing fungal diseases, such as Leaf Curl (Taphrina genus fungi), one of the main problems in the crop. Canopy management through branch pruning influences the distribution of sunlight and the quality of production.

The peach tree stem features relatively light yet strong wood, allowing for good sap conduction and fruit support. The plant develops short productive branches called spurs (or brachiblasts), essential for fruiting, as floral buds are concentrated on them. Stem management through annual pruning is fundamental to balance production, branch renewal, and light penetration into the canopy.

The peach tree requires sufficient winter chilling hours to break dormancy and initiate flowering and budding. The plant's deep root system ensures efficient water absorption during periods of low rainfall but requires well-drained soils. The most common rootstocks used in Brazil are plum or more resistant peach cultivars, to ensure adaptation to different soil types.

The seed contains a high oil content and an embryo sensitive to drying out, requiring a period of cold (stratification) to germinate properly. Plants originating from seeds show high genetic variability, being primarily used as rootstocks and in breeding programs. Commercial cultivars, however, are propagated by grafting, ensuring uniformity of flavor, size, and harvest time.

The early flowering of the peach tree, before the emission of leaves, makes the plant vulnerable to spring frosts, which can destroy the entire harvest. Although most varieties are self-pollinating, pollination by bees (Apis mellifera) is fundamental to increase fruit set and ensure larger and more uniform fruits. The Peach Blossom is a symbol of longevity and prosperity in many Asian cultures.
