Most varieties are dark blue or violet in color when mature, such as rabbit-eye blueberries, highbush blueberries, lowbush blueberries and the like, and few varieties are red. The fruits are spherical, elliptical, oblate or pear-shaped, the average single fruit weight is 0.5-2.5g, the diameters are 0.8-1.5cm, and the maximum single fruit weight of the rabbit-eye blueberries can reach 25 g. The blueberry fruit is generally ripe 70-90 days after the flower. The pulp is soft and juicy. The seeds are fine, and can be eaten with the pulp without affecting the taste.
In recent years, the blueberry cultivation area is continuously expanded, but the problems of small annual growth amount, poor stress resistance and low survival rate of blueberry seedlings generally exist in cultivation, so that how to strengthen the seedlings becomes a key problem in blueberry cultivation.
