Prunus salicina should not be confused with Prunus mume, a related species also commonly called Chinese plum or Japanese plum. Prunus japonica is also another tree that is a separate species despite having a Latin name similar to Prunus salicina's common name.

Names

edit

Some names for this plant, in addition to Japanese or Chinese plum, are Willow-leaf cherry, Asian Plum, in English, Ameixa or Ameixa-japonesa in Portuguese, 李 lǐ in Mandarin and Japanskt plommon in Swedish.[3]

The generic name, Prunus, comes from the Greek Prunum, meaning plum.[4] The specific epithet, salicina, is derived from the Latin word for willow.

Description

edit

Prunus salicina grows up to 9–12 metres (30–39 ft) tall, and its branches are purplish brown to reddish brown and its lateral shoots are yellowish red. [citation needed]

The leaves are 6–12 cm long and 2.5–5 cm broad, with scalloped margins, which when young is often mixed with simple gland-tipped teeth. The leaves' shape tend to be oblong, though it sometimes varies slightly more obovate (broader above the middle), narrowly elliptic, or in rare cases being slightly ovate (broader half below the middle). The base of the leaf is wedge-shaped, and its apex ranges from acute (pointed) to caudate (having a slender short tail). The upper side of the leaf is dark green and lustrous, and have 6 or 7 secondary veins on either side of midvein, not extending to leaf margin.[5]

The winter buds of the Prunus salicina are purplish red, and are occasionally hairy at scale margins, though this is rare. The flowers are produced in early spring, around April, each about 2 cm in diameter with five white petals, and come in groups of 3. The pedicel is 1–1.5 cm, and its sepals are oblong-ovate and about 5mm, hairless on the outside, with loosely serrated margins. The sepal's apex is acute to obtuse. The petals of the flower are white, oblong-obovate, with a wedge-shaped base and a jagged margin near the apex. The ovary is hairless and the stigma disc-shaped.[5]

The fruit is a drupe, 4–7 cm in diameter with yellow-pink flesh. The skin can be yellow, red, or sometimes green or purple, and has a powdery coating. The shape of the drupe is spherical, egg-shaped, or conical, and it is 3.5–5 cm in diameter, though it can reach 7 cm in diameter in horticultural forms.[5] They fruit from July to August. When fully ripe it can be eaten raw.[6] In comparison to the Prunus domestica, the Prunus salicina, fruit has a higher flavor and aroma, better texture, more color, bigger size, and good nutritional values.[7]

The pit of the Prunus salicina is ovoid (egg-shaped) to oblong, and wrinkled.[5]

Growth pattern

edit

The Japanese plum, like other Prunus fruit tree species, is mostly self-incompatible and requires cross pollination to ensure fruit set because this genus is unable to bear fruit parthenocarpically. Several cultivars or varieties have however been identified with self-compatibility.[8]

Distribution and habitat

edit

Prunus salicina is native to China, Taiwan, Myanmar, Laos and Vietnam.[1] In China, it grows in sparse forests, forest margins, thickets, along trails in mountains and stream sides in valleys, at elevations of 200–2600 meters.[5] It grows best in temperate warmer regions, as it requires moderate temperatures and is usually early flowering.[9]

The domestication center of origin of Prunus salicina is southwestern China, from the Yangtze River Basin.[10] Wild populations of this species are reported as thriving in the provinces of Shaanxi and Gansu.[11] It is recorded as an introduced species in both Australia and Japan.[3]

Ecology

edit

Prunus salicina is strongly dependent on endomycorrhizal relationships, similar to other species of plum.[12] Ectomycorrhizal relationships with the fungus Hebeloma hiemale was shown to increase net growth in Prunus cerasifera  x salicina, compared to chemical fertilizer, compost and a control.[13]

The effects of the Prunus salicina in improving soil in karst areas in China, have been mixed. A study conducted in Guiyang Karst Park, Guizhou, China, concluded that Prunus salicina, in combination with the moss species, Homomallium plagiangium, Cyrto-hypnum pygmaeuman and Brachythecium perminusculum, and the herbs Veronica arvensis and Youngia japonica, were suitable pioneer plant species to cultivate for use in restoration of regions of karstic soil erosion.[14] Planted on cropland suffering from rocky desertification, in the city of Hechi, Prunus salicina increased the carbon-to-nitrogen ratio, and the soil quality at the 10–20 cm soil layer, though in general, it had limited influence on soil improvement because of its fast growing and high output, increasing the absorption of nutrients from the soil.[15]

Cultivation

edit

The main producing country of Japanese plums is China, followed by the United States of America, Mexico, Italy, Spain, Pakistan, Korea, Australia, Chile, France, South Africa and Argentina. The most famous variety of this fruit in Vietnam is the Tam Hoa plum grown in Bắc Hà town, in Lào Cai Province.

Japanese cultivars were introduced into the United States in the latter half of the 19th century, where subsequent breeding produced many more cultivars, generally with larger fruit. Plant breeder Luther Burbank developed a number of cultivars by hybridizing Prunus salicina with Prunus simonii and other native North American diploid plums such as Prunus americana, Prunus hortulana or Prunus munsoniana. In the late 19th and early 20th centuries, from these hybridizations Burbank selected cultivars such as ‘Beauty’, ‘Eldorado’, ‘Formosa’, ‘Gaviota’, ‘Santa Rosa’, ‘Shiro’, and ‘Wickson’, some of which are still widely grown.[16][17] One of the famous cultivars, “Santa Rosa”, named after the city in California.[18]

Most of the fresh plums sold in North American supermarkets are Prunus salicina cultivars or hybrids. They are grown on a large scale in a number of other countries, for example, they dominate the stone fruit industry in Western Australia.[19] In France in 2020, Japanese plums production volumes are now higher than that of European plums.[20]

There is an important work of breeding and selection of new Japanese plum cultivars and varieties around the world from different breeding programs. As a result, the Community Plant Variety Office of the European Union (CPVO) registered 155 new Japanese plum cultivars from 1995 to 2021.[21] The table below presents a short list of varieties.

Cultivars Description
'Bubblegum'/"Toka" This cultivar is disease-resistant, and is known to be a reliable pollinator. It is a hybrid petween the Prunus americana and the Prunus salicina. Its fruit is very juicy and sweet, and the skin is reddish bronze.[22]
'Burbank' This cultivar starts to bear fruits in 2-3 years. It needs cross pollination from different Japanese plum cultivars. It can be used as a landscape flowering tree in spring or a shade tree in summer. It grows 13-24'' per year.[23]
'Byrongold' This cultivar produces a large quantity of fruit. It has problems with leaf scald and a chilling requirement of 450 units. It is recommended to have two cultivars planted to ensure better fruiting. [24]
'Early Golden' This cultivar bears round, golden,firm, freestone plums with high red blush. While not as large as Shiro, the cultivar ripens 10-14 days earlier. Trees are very vigorous, outgrowing other plum cultivars. It has a biennial fruiting habit but can be eliminated with proper thinning and irrigation.[25]
'Golden Japan' This cultivar's fruit is medium-sized, rounded, golden yellow, sometimes with pink to scarlet red dots or small cheeks when fully ripe on the tree. The taste is very sweet and the flesh is pale yellow and juicy, and clingstone. It has thick skin.[26]
'Methley' This cultivar has a heavy bearing variety that will start to produce fruit in 2-4 growing seasons. The early blossom is easily susceptible to spring frost damage. It is self fertile, but planting two cultivars is recommended. Heat tolerant. [27]
'Santa Rosa' The Santa Rosa cultivar produces white spring blooms and is commonly eaten fresh, canned or cooked, The plums are large in size with red to purple coloring, ripening midseason.[28]
‘Shiro" The 'Shiro" cultivar produces medium size fruit with yellow skin and flesh, and grows in warm sheltered sites only. The white, early spring blossom is prone to frost damage and protection is usually needed.[29]
'Ozark Premier' Ozark Premier Japanese plum is a cross between 'Methley' and 'Burbank'. It is self-fruitful but planting two different cultivars is recommended to ensure better fruiting. Certain chilling hours is required.[30]
'Vampire' This cultivar bears medium-large fruits, late mid-season. It has a blend of shiny green and ruby red skin. The flesh is red and very juicy. Is cold-tolerant[25]
'Vanier' This cultivar bears medium-sized, bright red clingstone fruits with yellow flesh, maturing 2 weeks later than Shiro. Fruit can be stored for 2-3 weeks. Trees are precocious, vigorous and have an upright growth habit. [25]

Threats

edit

In open field cultivation this species is vulnerable to several vector or pollen-borne viral diseases affecting Prunus including Plum pox virus and Prunus necrotic ringspot virus. Japanese plums are also well-known for their susceptibility to European stone fruit yellows phytoplasma, with strong symptoms including yellowing, leaf roll, premature fruit drop and dieback.[31] Additional threats to this species remain unknown, and while there are several known threats to the forests of China, including logging, deforestation and air and water pollution it is unknown whether these have a direct effect on Prunus salicina. As of 2023, its threat status on the IUCN Red List is Least Concern, and this species' population is stable.[11] The IUCN Red List recommends "the incorporation of population management and monitoring in protected areas where this species is known to occur" and "additional ex situ collection, ensuring the full range of genetic diversity found in the wild is represented in genebanks."[11]

Uses

edit

Culinary

edit

Since Prunus salicina Linn. fruit has a short-shelf life (3–4 days) under room temperature as well as cold storage (1–2 weeks), it is often prepared into jams, jellies, wine, and other beverages. Black pepper, coriander, cumin, clove, black cardamom, saffron, nutmeg, cinnamon, poppy seed, ginger, woodfordia, asparagus, withania, adhatoda, and rosemary have been reported to be used in preparing aromatized plum wine. The Santa Rosa plum cultivar produces the best quality wine, in comparison Methley, and Green Gage.[32]

In China, candied fruits are also sold preserved, flavoured with sugar, salt, and liquorice. A study on foraging in the Gongba Valley (Zhouqu county in Gansu, China) identified Prunus salicina as one of the most commonly eaten wild fruits.[11] Liquor made from Prunus salicina fruit is mixed with Prunus mume liquor, and oolong tea liquor to make a Japanese-style plum liquor, wumeijiu (smoked plum liquor), in Taiwan.[33]

In Japan, while it is less commonly eaten than closely related Prunus mume, it is pickled and colored in a similar manner. Especially in Eastern Japan, many summer festivals sell pickled fruits covered in mizuame candy called anzuame (apricot candy, as apricots were traditionally used for the recipe).[34]

In both countries, it is also used half ripe as a flavouring in a liqueur called sumomo shu (すもも酒) in Japanese.[35]

Medicinal

edit

The fruits are also used in Traditional Chinese medicine, to enhance immunity against infectious agents and to treat cancers.[37] Japanese plums cv. Crimson Globe may be taken as a source of antioxidants with a potential to counteract oxidation.[38] Prunus salicina fruit may contain immunostimulatory (stimulating the immune system by inducing activation or increasing activity) components that potentially may be useful in human and veterinary medicine.[37] Compared to other fruits, Japanese plums, include a reasonable source of fiber and proper source of bioactive compounds (such as vitamin C and phenolic composition).[7] Their phenolic composition positively correlates to their antioxidant properties. [39][40] A study evaluating ethanol extracts from 400 herbs found that the Japanese plum was the most effective Glucosyltransferase (GTF) inhibitor and showed the highest antibacterial activity.[41] There has been research into whether the fruit of the Japanese plum has cancer-protective effects because of its antioxidant properties, but as of 2023, it is unclear what role antioxidants in general, play in cancer protection and treatment.[42] [43]

Toxicity

edit

As with other stone fruits, the pit and leaves are poisonous to humans, as they contain amydalin, which breaks down to hydrogen cyanide.[44] [45] While poisoning from unintentional ingestion of a few pits is unlikely, it recommended to avoid ingestion, and to never consume crushed up pits.[46]
