Myrica rubra, also called yangmei, mountain peach, Chinese Bayberry, Japanese Bayberry, Red Bayberry, Yumberry, Waxberry, or Chinese strawberry (and often mistranslated from Chinese as arbutus) is a subtropical tree grown for its sweet, crimson to dark purple-red, edible fruit.

Description

It is a small to medium-sized evergreen tree growing up to 10–20 m (33–66 ft) high, with smooth gray bark and a uniform spherical to hemispherical crown. It is dioecious, with separate male and female plants. It tolerates poor acidic soils. The root system is 5–60 cm (2.0–23.6 in) deep, with no obvious taproot.

The fruit is spherical, 1.5–2.5 cm (0.59–0.98 in) in diameter, with a knobby surface. The surface color is typically a deep, brilliant red, but may vary from white to purple. The flesh color is similar to surface color, or somewhat lighter. The flesh is sweet and very tart. At the center is a single seed, with a diameter about half that of the whole fruit.

Taxonomy

Also called Morella rubra Loureiro; Myrica rubra var. acuminata Nakai. It is usually cited as Myrica rubra (Loureiro) by Siebold & Zuccarini. However, in their publication of 1846, Siebold & Zuccarini provided a description only, with no reference, direct or indirect, to Morella rubra Loureiro (1790). Therefore, the name Myrica rubra Siebold & Zuccarini must be treated as new, preventing the combination in Myrica of Loureiro’s earlier name.

Distribution and habitat

It is native to eastern Asia, mainly in China, where it has been grown for at least 2000 years. Chinese cultivation is concentrated south of the Yangtze River, where it is of considerable economic importance. Its niche is forests on mountain slopes and valleys at altitudes of 100–1500 m. It is native to Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hunan, Jiangsu, Jiangxi, Sichuan, Yunnan, and Zhejiang.[1] Also naturalized in Taiwan, Japan, Nepal, Korea, and the Philippines.

Uses

The tree is used as ornaments for parks and streets. It is also a traditional tree used in composing classical East Asian gardens.

Products

Some cultivars with large fruit, up to 4 cm in diameter, have been developed. Besides fresh consumption, the fruits may be dried, canned, soaked in baijiu (Chinese liquor), or fermented into alcoholic beverages.[2] Dried fruits are often prepared in the manner of dry huamei (Prunus mume with flavorings such as licorice). The juice has been commercialised under the brand name "Yumberry" under which name it is trade-marked in the EU. In Yunnan Province in China, there are two main types of yangmei, a sour type used for making dried fruit and a sweet type used for juice and fresh eating.

Other uses include

    bottled pasteurized juice or juice blends

    dye prepared from the bark

    yogurt flavoring

    blended jam and preserves

Research and components

Various species of Myrica have been studied scientifically for horticultural characteristics or phytochemicals implicated with health benefits. Dating to 1951, the horticultural literature includes studies on

    nitrogen-fixing ability of the root nodules system

    presence of Frankia bacteria having nitrogen-fixing properties in root nodules

    microbial characteristics of the subcanopy soil

    niche characteristics in the forest environment

    growth of pollen tubes

The scientific literature is diverse, with studies of phytochemicals from bark, leaves and fruit. Significant progress has been reported on polyphenols, particularly ellagic acid, prodelphinidin-type tannins, such as prodelphinidin B-2 3,3'-di-O-gallate,[9] and anthocyanins, antioxidant activity, anti-cancer and anti-viral properties.  Cyclic diarylheptanoids, such as myricanone glycosides, can be isolated from the bark of M. rubra.

An extract from fruit called myricerone blocks a receptor for the peptide, endothelin, an important mediator of blood vessel constriction, indicating potential for drug development.

Culture

In Japan, it is the prefectural flower of Kōchi and the prefectural tree of Tokushima. The plant's name appears in many old Japanese poems.

Propagation:

Seeds need a warm-cold stratification to germinate. Place the seeds in a zip-lock bag of slightly damp fine sand or perlite. Put the bag in a warm place,  approx. 25°C. Check them regularly to ensure they are still moist (but not soggy). After 12 weeks put the bag in a refrigerator (4-°C) for a period of 12 weeks. Check them regularly and plant the sprouted seeds in potting soil. Place the planted seedlings in a bright, warm place, approx. 15-20°C.
