Pomegranate is a deciduous tree or shrub belonging to the genus Pomegranate. The history of pomegranate cultivation in China can be traced back to the Han Dynasty. According to Lu Gong's records, it was introduced from the Western Regions by Zhang Qian. Fruits are rich in nutrition, and the content of vitamin C is one or two times higher than that of apples and pears. I believe many friends have eaten pomegranate, but they have never seen what pomegranate trees look like. Let's see what pomegranate trees look like!

tree trunk

Pomegranate is a tropical evergreen tree with natural round crown, yellowish brown roots, vigorous growth and easy rooting and tillering in the rhizosphere. The height of the tree can reach 5 ~ 7 meters, generally 3 ~ 4 meters, while the dwarf pomegranate is only about 1 meter or even lower. The trunk is grayish brown with tumor-like protrusions on it, and the trunk is mostly twisted to the left.

Crown of a tree

Pomegranate has many branches in the crown, angular and square shoots, and the branchlets are flexible and not easy to break. Primary branches are staggered, opposite on strong branchlets, with small spines. The length of thorns is related to the variety and growth. Lush trees have many thorns, but old trees have few thorns. The colors of flower buds change with the seasons, including purple, green and orange.

tree leaf

Pomegranate leaves are opposite or clustered, long-lanceolate to oblong, or elliptic-lanceolate, 2-8 cm long and 1-2 cm wide, sharp, shiny on the surface, with convex midvein on the back and short petiole.

flower

Pomegranate flowers are bisexual, depending on whether the ovary is developed, including bell-shaped flowers and tubular flowers. The former is good at fertilization, while the latter often withers and bears no fruit. Petals obovate, as many as sepals and alternate, arranged in imbricate shape. Flowers are divided into single petals and double petals. Double petal variety has many petals and strong sterility, with dozens of petals. Flowers are red, white, yellow, pink and agate. Stamens are numerous, filaments are hairless. Pistil has 1 style, longer than stamens, with 4 ~ 8 carpels and lower ovary.

fruit

Pomegranate fruit becomes a large multi-chamber and multi-seed berry when it matures, and each chamber has many seeds. The exocarp is fleshy, bright red, red or white, juicy, sweet and sour, and is an edible part. The inner seed coat is horny, and some of it degenerates and softens, which is soft-seeded pomegranate. Pomegranate blooms in May and June, and pomegranate blooms like fire. The fruiting period is from September to 65438+ 10.
