Xinchang Blueberries

　　Blueberry, as the name suggests, refers to blue-colored berries. There are two types: one is a low shrub, wild and low-growing, with small berries but high anthocyanin content; the other is cultivated blueberries, which can grow up to 240 cm tall, with larger fruits, more moisture, and relatively lower anthocyanin content.

　　Blueberries are small berries with beautiful, eye-catching blue color, covered by a layer of white bloom. The flesh is delicate, and the seeds are extremely small. Blueberry fruits typically weigh between 0.5–2.5g, with the largest reaching up to 5g. They are 100% edible, sweet and tangy in taste, and have a pleasantly fragrant aroma, making them an excellent fresh fruit.

　　Blueberry flowers have ornamental value

　　　　 Blueberry flowers grow in racemes.[2] Most of the inflorescences are lateral, though sometimes terminal. Flowers grow singly or in pairs in leaf axils. Blueberry flower buds usually form at the tips of branches. In spring, flower buds begin to sprout 3–4 weeks before full bloom. Once the flower buds sprout, leaf buds start to grow, but they only reach their full length by the time of full bloom. The plant form of blueberries features shrubby growth, with highly variable tree heights. Rabbiteye blueberries can grow up to 10 m tall, though they are often pruned to around 3 m in cultivation; highbush blueberries generally range from 1–3 m; half-high blueberries are about 50–100 cm tall; and lowbush blueberries are 30–50 cm tall.

　　Blueberry Leaves

　　　　The leaves are alternate. Highbush, half-high, and lowbush blueberries shed their leaves before winter, while rabbiteye blueberries are evergreen, retaining their leaves on the tree for 2–3 years. Leaf size ranges from 0.7–3.5 cm for lowbush blueberries to 8 cm for highbush blueberries, varying in length. The most common leaf shape is oval. Most varieties have hairy undersides, and some have fuzz on flowers and fruits, though lowbush blueberry leaves rarely have hair.

　　Blueberry Roots

　　　　The root system lacks root hairs and has limited absorption capacity. Blueberry roots are fine and fibrous, with fine roots having a diameter of 50–75 micrometers before branching. Almost all blueberry fine roots are colonized by endomycorrhizal fungi, helping to overcome the difficulty in water and nutrient absorption caused by the lack of root hairs. Research shows that this mycorrhizal colonization is beneficial to blueberry growth.
