Apricot Tree

Prunus armeniaca

1. Identification and origin

The apricot tree, also known as apricot (Prunus armeniaca L.), is a fruit species of the family Rosaceae, native to the regions of Central Asia, particularly the area between China and the Armenian plateau. It has been cultivated for millennia and has spread widely throughout the Mediterranean. It produces aromatic drupaceous fruits, with sweet pulp and an orange colour, much appreciated for fresh consumption and processing.

2. Economic importance

The apricot tree has economic relevance in temperate and Mediterranean climate regions. The fruits are valued for fresh consumption, drying, jams, jellies and the food industry. The crop is important in traditional and modern orchards, with growing interest in varieties adapted to cold springs and early flowering.

3. Botanical characterization

A medium-sized, deciduous tree, with a rounded crown. The leaves are simple, ovate, with a serrated margin. The flowers are white to pinkish, solitary or in pairs, very sensitive to late frosts. The fruit is a rounded drupe, with a velvety epicarp and sweet pulp. The stone contains a bitter or sweet seed, depending on the variety.

4. Soil and climate requirements

It prefers temperate climates with cold winters and hot, dry summers. It is sensitive to late frosts due to early flowering. It develops best in deep, well-drained, slightly alkaline soils (pH 6.5–8.0). It tolerates some drought, but benefits from regular irrigation in critical periods.

5. Main pests

• Fruit fly (Ceratitis capitata): direct damage to the fruits.
• Aphids (Aphididae): leaf curling and transmission of viral diseases.
• Scale insects (Coccoidea): sap sucking and honeydew production.
• Borer and oriental fruit moth (Anarsia lineatella, Grapholita molesta): galleries in branches and fruits.
• Nematodes (Meloidogyne spp.): root galls and plant decline.

6. Main diseases

• Brown rot (Monilinia laxa, M. fructigena): fruit rot and branch canker.
• Shot hole (Wilsonomyces carpophilus): leaf perforations and fruit lesions.
• Bacterial canker (Pseudomonas syringae pv. syringae): necroses and branch death.
• Root rots (Phytophthora spp.): wilting and decline.
• Sharka virus (PPV): ring spots and fruit devaluation.

7. General crop management

Management includes the choice of varieties adapted to the local climate, especially regarding the risk of late frosts. Pruning should favour the entry of light and the renewal of fruiting branches. Irrigation should be moderate, avoiding waterlogging. Monitoring of fruit fly, brown rot and shot hole is essential to ensure commercial quality. Harvesting must be carried out at the optimal point of ripening, avoiding mechanical damage.
