Prunus pyrifolia is a tall, upright tree that grows between 7 and 15 meters high. Its branches are thin and can be dark brown or purplish brown, becoming smooth as they age. Young branches are covered in soft, tawny hairs. The leaves are thick and pointed at the base, with a fuzzy edge. The stipules (small leaf-like structures at the base of the leaf stalk) are 1–1.5 cm long, with a linear shape and a pointed tip. Leaves measure 7–12 cm in length and 4–6.5 cm in width; they can be either oval or elongated (oblong), and are smooth or covered in fine brown hairs when young. The base of the leaf is rounded or slightly heart-shaped, and the edge has small, tooth-like projections. Flower buds are short and rounded, growing singly on very short stems. The flowers, which come in clusters of 6–9, are white and have a cup-shaped base. Each flower is about 2.5–3.5 cm across and consists of 5 sepals, 5 petals, 20 stamens, and 4–5 carpels (the parts of the flower that develop into fruit). The fruit is round or slightly pear-shaped, about 2–2.5 cm in diameter, with a brownish color and pale dots, and has a stem 3.5–5.5 cm long [4].

Food: The fruit is edible, with white, crisp, and extremely juicy flesh. It offers a balanced flavor of sweet and sour, with a light, refreshing taste. When fully ripe, the fruit is firm, crisp, and juicy, making it ideal for eating fresh or incorporating into fruit salads and pies. [7], [8] Medicine: [8] ● Antiseptic (prevents or slows the growth of microorganisms, used to prevent infection) ● Astringent (causes the contraction of body tissues, typically used to reduce bleeding or tighten skin) ● Febrifuge (reduces fever) ● Nervine (calms the nerves or reduces nervous tension) ● Pectoral (relates to the chest, often used to treat respiratory issues)

Temperature: [8]
● The plant is hardy (resilient) to at least -15°C and can tolerate a variety of climates, including areas with atmospheric pollution.
Rainfall: [8]
● Established plants are drought tolerant and can also handle excessive moisture, making them adaptable to various rainfall conditions.[8]:
Planting soil conditions
● The plant prefers a well-drained loam (fertile soil) in full sun but also grows well in heavy clay soils. It tolerates a range of soil types as long as they are moderately fertile, though fruit production is reduced in light shade. Root structure is branching, with a heart root system that divides from the crown into several primary roots extending down and outward, important for nutrient and water absorption. [8]

Harvesting: P. pyrifolia is harvested between late September and late December. Nashi pear can be picked prior to ripening or when completely ripe on the tree [7].

Post-harvest management: P. pyrifolia should be refrigerated at 0°C after harvest and stored at over 90% relative humidity to prevent water loss and preserve the texture of both the skin and flesh. When harvested at optimal maturity, the fruit can be stored for up to 20 weeks. y [7].
