  • Cherry 

    cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe (stone fruit).

    Commercial cherries are obtained from cultivars of several species, such as the sweet Prunus avium and the sour Prunus cerasus. The name ‘cherry’ also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus Prunus, as in “ornamental cherry” or “cherry blossom“. Wild cherry may refer to any of the cherry species growing outside cultivation, although Prunus avium is often referred to specifically by the name “wild cherry” in the British Isles.

    Prunus subg. Cerasus contains species that are typically called cherries. They are known as true cherries[1] and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. P. serrula; some species with short racemes, e.g. P. maacki), and by having smooth fruit with no obvious groove.[2] Examples of true cherries are:

    Bush cherries

    Prunus tomentosa, Nanking cherry (a bush cherry species)

    Bush cherries are characterized by having three winter buds per axil.[2] They used to be included in Prunus subg. Cerasus, but phylogenetic research indicates they should be a section of Prunus subg. Prunus.[1] Examples of bush cherries are:

    • Prunus cistena Koehne – purple-leaf sand cherry
    • Prunus humilis Bunge – Chinese plum-cherry or humble bush cherry
    • Prunus japonica Thunb. – Korean cherry
    • Prunus prostrata Labill. – mountain cherry, rock cherry, spreading cherry or prostrate cherry
    • Prunus pumila L. – sand cherry
    • Prunus tomentosa Thunb. – Nanking cherry, Manchu cherry, downy cherry, Shanghai cherry, Ando cherry, mountain cherry, Chinese dwarf cherry, Chinese bush cherry

    Etymology

    The Cherry Seller by Sara Troost (Netherlands, 18th century)

    The English word cherry derives from Old Northern French or Norman cherise from the Latin cerasum,[3] referring to an ancient Greek region, Kerasous (Κερασοῦς) near GiresunTurkey, from which cherries were first thought to be exported to Europe.[4]

    The word “cherry” is also used for some species that bear fruits with similar size and shape even though they are not in the same Prunus genus; some of these species include the “Jamaican cherry” (Muntingia calabura) and the “Spanish cherry” (Mimusops elengi).[5]

    Antiquity

    The indigenous range of the sweet cherry extends through most of Europe, western Asia, and parts of northern Africa, and the fruit has been consumed throughout its range since prehistoric times. A cultivated cherry is recorded as having been brought to Rome by Lucius Licinius Lucullus from northeastern Anatolia, also known as the Pontus region, in 72 BCE.[6]

    Cherries were introduced into England at Teynham, near Sittingbourne in Kent, by order of Henry VIII, who had tasted them in Flanders.[7][8][9]

    Cherries, along with many other fruiting trees and plants, probably first arrived in North America around 1606 in the New France colony of Port Royal, which is modern-day Annapolis Royal, Nova Scotia. Richard Guthrie described in 1629, the “fruitful valley adorned with…great variety of fruit trees, chestnuts, pears, apples, cherries, plums and all other fruits.”[10]

    Cultivation

    Cherry time by Salvatore Postiglione

    The cultivated forms are of the species sweet cherry (P. avium) to which most cherry cultivars belong, and the sour cherry (P. cerasus), which is used mainly for cooking. Both species originate in Europe and western Asia; they usually do not cross-pollinate. Some other species, although having edible fruit, are not grown extensively for consumption, except in northern regions where the two main species will not grow. Irrigation, spraying, labor, and their propensity to damage from rain and hail make cherries relatively expensive. Nonetheless, demand is high for the fruit. In commercial production, sour cherries, as well as sweet cherries sometimes, are harvested by using a mechanized “shaker.”[11] Hand picking is also widely used for sweet as well as sour cherries to harvest the fruit to avoid damage to both fruit and trees.

    Common rootstocks include Mazzard, Mahaleb, Colt, and Gisela Series, a dwarfing rootstock that produces trees significantly smaller than others, only 8 to 10 feet (2.5 to 3 meters) tall.[12] Sour cherries require no pollenizer, while few sweet varieties are self-fertile.[12]

    A cherry tree will take three to four years once it is planted in the orchard to produce its first crop of fruit, and seven years to attain full maturity.[13]

    Growing season

    Like most temperate-latitude trees, cherry trees require a certain number of chilling hours each year to break dormancy and bloom and produce fruit. The number of chilling hours required depends on the variety. Because of this cold-weather requirement, no members of the genus Prunus can grow in tropical climates. (See “production” section for more information on chilling requirements)

    Cherries have a short growing season and can grow in most temperate latitudes.[13] Cherries blossom in April (in the Northern Hemisphere) and the peak season for the cherry harvest is in the summer. In southern Europe in June, in North America in June, in England in mid-July, and in southern British Columbia (Canada) in June to mid-August. In many parts of North America, they are among the first tree fruits to flower and ripen in mid-Spring.

    In the Southern Hemisphere, cherries are usually at their peak in late December and are widely associated with Christmas. ‘Burlat’ is an early variety which ripens during the beginning of December, ‘Lapins’ ripens near the end of December, and ‘Sweetheart’ finish slightly later.[14]

    Pests and diseases

    Cherries with Monilinia laxa

    Generally, the cherry can be a difficult fruit tree to grow and keep alive.[12] In Europe, the first visible pest in the growing season soon after blossom (in April in western Europe) usually is the black cherry aphid (“cherry blackfly,” Myzus cerasi), which causes leaves at the tips of branches to curl, with the blackfly colonies exuding a sticky secretion which promotes fungal growth on the leaves and fruit. At the fruiting stage in June/July (Europe), the cherry fruit fly (Rhagoletis cingulata and Rhagoletis cerasi) lays its eggs in the immature fruit, whereafter its larvae feed on the cherry flesh and exit through a small hole (about 1 mm diameter), which in turn is the entry point for fungal infection of the cherry fruit after rainfall.[15] In addition, cherry trees are susceptible to bacterial cankercytospora canker, brown rot of the fruitroot rot from overly wet soil, crown rot, and several viruses.[12]

    Europe

    Major commercial cherry orchards in Europe are in TurkeyItalySpain and other Mediterranean regions, and to a smaller extent in the Baltic States and southern Scandinavia.

    In France since the 1920s, the first cherries of the season come in April/May from the region of Céret (Pyrénées-Orientales),[41] where the local producers send, as a tradition since 1932, the first crate of cherries to the president of the Republic.[42]

    North America

    In the United States, most sweet cherries are grown in WashingtonCaliforniaOregonWisconsin, and Michigan.[43] Important sweet cherry cultivars include BingUlsterRainier, Brooks, Tulare, King, and Sweetheart.[44] Both Oregon and Michigan provide light-colored ‘Royal Ann’ (‘Napoleon’; alternately ‘Queen Anne’) cherries for the maraschino cherry process. Most sour (also called tart) cherries are grown in Michigan, followed by UtahNew York, and Washington.[43] Sour cherries include ‘Nanking’ and ‘Evans.’ Traverse City, Michigan is called the “Cherry Capital of the World”,[45] hosting a National Cherry Festival and making the world’s largest cherry pie. The specific region of northern Michigan known for tart cherry production is referred to as the “Traverse Bay” region.

    Most cherry varieties have a chilling requirement of 800 or more hours, meaning that in order to break dormancy, blossom, and set fruit, the winter season needs to have at least 800 hours where the temperature is below 7 °C (45 °F). “Low chill” varieties requiring 300 hours or less are Minnie Royal and Royal Lee, requiring cross-pollinization, whereas the cultivar, Royal Crimson, is self-fertile.[46] These varieties extend the range of cultivation of cherries to the mild winter areas of southern US. This is a boon to California producers of sweet cherries, as California is the second largest producer of sweet cherries in the US.[47]

    Native and non-native sweet cherries grow well in Canada’s provinces of Ontario and British Columbia where an annual cherry festival has been celebrated for seven consecutive decades in the Okanagan Valley town of Osoyoos.[48] In addition to the Okanagan, other British Columbia cherry growing regions are the Similkameen Valley and Kootenay Valley, all three regions together producing 5.5 million kg annually or 60% of total Canadian output.[49] Sweet cherry varieties in British Columbia include ‘Rainier’, ‘Van’, ‘Chelan’, ‘Lapins’, ‘Sweetheart’, ‘Skeena’, ‘Staccato’, ‘Christalina’ and ‘Bing.’

    Australia

    In Australia, cherries are grown in all the states except for the Northern Territory. The major producing regions are located in the temperate areas within New South Wales, Victoria, South Australia and Tasmania. Western Australia has limited production in the elevated parts in the southwest of the state. Key production areas include YoungOrange and Bathurst in New South WalesWandin, the Goulburn and Murray valley areas in Victoria, the Adelaide Hills region in South Australia, and the Huon and Derwent Valleys in Tasmania.

    Key commercial varieties in order of seasonality include ‘Empress’, ‘Merchant’, ‘Supreme’, ‘Ron’s seedling’, ‘Chelan’, ‘Ulster’, ‘Van’, ‘Bing’, ‘Stella’, ‘Nordwunder’, ‘Lapins’, ‘Simone’, ‘Regina’, ‘Kordia’ and ‘Sweetheart’. New varieties are being introduced, including the late season ‘Staccato’ and early season ‘Sequoia’. The Australian Cherry Breeding program is developing a series of new varieties which are under testing evaluation.[50]

    The New South Wales town of Young is called the “Cherry Capital of Australia” and hosts the National Cherry Festival.

    Nutritional value

    Raw sweet cherries are 82% water, 16% carbohydrates, 1% protein, and negligible in fat (table). As raw fruit, sweet cherries provide little nutrient content per 100 g serving, as only dietary fiber and vitamin C are present in moderate content, while other vitamins and dietary minerals each supply less than 10% of the Daily Value (DV) per serving, respectively (table).[51]

    Compared to sweet cherries, raw sour cherries contain 50% more vitamin C per 100 g (12% DV) and about 20 times more vitamin A (8% DV), beta-Carotene in particular (table).[52]

    Health risks

    The cherry kernels, accessible by chewing or breaking the hard-shelled cherry pits, contain amygdalin, a chemical that releases the toxic compound hydrogen cyanide when ingested. The amount of amygdalin in each cherry varies widely, and symptoms would show only after eating several crushed pits (3–4 of the Morello variety or 7–9 of the red or black varieties). Swallowing the pits whole normally causes no complications.[55]

    Other uses

    Cherry wood is valued for its rich color and straight grain in manufacturing fine furniture, particularly desks, tables and chairs.[56][57]

  • Pine Nuts

    Pine nuts, also called piñón (Spanish: [piˈɲon]), pinoli (Italian: [piˈnɔːli]), or pignoli, are the edible seeds of pines (family Pinaceae, genus Pinus). According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally[1] owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food.[1][2][3][4] The biggest producers of pine nuts are ChinaRussiaNorth KoreaPakistan and Afghanistan.[5]

    As pines are gymnosperms, not angiosperms (flowering plants), pine nuts are not “true nuts“; they are not botanical fruits, the seed not being enclosed in an ovary which develops into the fruit, but simply bare seeds—”gymnosperm” meaning literally “naked seed” (from Ancient Greekγυμνόςromanizedgymnoslit.‘naked’ and σπέρμαsperma, ‘seed’). The similarity of pine nuts to some angiosperm fruits is an example of convergent evolution.

    Species and geographic spread

    [edit]

    In Asia, two species, in particular, are widely harvested: Korean pine (Pinus koraiensis) in northeast Asia (the most important species in international trade) and chilgoza pine (P. gerardiana) in the western Himalaya. Four other species, Siberian pine (P. sibirica), Siberian dwarf pine (P. pumila), Chinese white pine (P. armandii) and lacebark pine (P. bungeana), are also used to a lesser extent. Russia is the largest producer of P. sibirica nuts in the world,[6] followed by either Mongolia or Afghanistan. They each produce over 10,000 metric tons (9,800 long tons; 11,000 short tons) annually, most of it exported to China.[7][8][9]

    Pine nuts produced in Europe mostly come from the stone pine (P. pinea), which has been cultivated for its nuts for over 5,000 years. Pine nuts have been harvested from wild trees for far longer. The Swiss pine (P. cembra) is also used, to a very small extent.

    In North America, the main species are three of the pinyon pinesColorado pinyon (P. edulis), single-leaf pinyon (P. monophylla), and Mexican pinyon (P. cembroides). The other eight pinyon species are used to a small extent, as is gray pine (P. sabineana), Coulter pine (P. coulteri), Torrey pine (P. torreyana), sugar pine (P. lambertiana) and Parry pinyon (P. quadrifolia). Here, the nuts themselves are known by the Spanish name for the pinyon pine, piñón (plural: piñones).

    In the United States, pine nuts are mainly harvested by Native American and Hispano communities, particularly in the Western United States and Southwestern United States, by the ShoshonePaiuteNavajoPuebloHopiWashoe, and Hispanos of New Mexico.[10] Certain treaties negotiated by tribes and laws in Nevada guarantee Native Americans’ right to harvest pine nuts,[11] and the state of New Mexico protects the use of the word piñon for use with pine nuts from certain species of indigenous New Mexican pines.[12]

    Pollination and seed development

    [edit]

    Pine nuts will not reach full maturity unless the environmental conditions are favorable for the tree and the cone. The time to maturity varies depending on the species.

    For some American species, development begins in early spring with pollination. A tiny cone, about the size of a small marble, will form from mid-spring through the end of summer; this immature cone will temporarily cease growing and remain dormant until the following spring, then grow again until it reaches maturity near the end of its second summer. The mature piñon pine cone is ready to harvest ten days before the green cone begins to open. A cone is harvested by placing it in a burlap bag and exposing it to a heat source such as the sun to begin drying. It takes about 20 days until the cone fully opens. Once it is fully open and dry, the seed can be easily extracted in various ways. The most common and practical extraction method used is the repeated striking of the burlap bag containing the cone(s) against a rough surface to cause the cone(s) to shatter, leaving just the job of separating by hand the seed from the residue within the bag.

    Another option for harvesting is to wait until the cone opens on the tree (as it naturally will) and harvest the cone from the piñon pine, followed by the extracting process mentioned above. Fallen seeds can also be gathered beneath the trees.

    Ecology and status

    [edit]

    Because pine nuts are an important food source for many animals, overharvesting of pine nuts threatens local ecosystems, an effect occurring during the early 21st century with increased culinary uses for pine nuts.[13] In the United States, millions of hectares of productive pinyon pine woods have been destroyed due to conversion of lands, and in China and Russia, destructive harvesting techniques (such as breaking off whole branches to harvest the cones) and removal of trees for timber have led to losses in production capacity.[3][13]

    Elevation and pinecone production

    [edit]

    Some growers claim that the elevation of the pinyon pine is an important determinant of the quantity of pine cone production and, therefore, will largely determine the number of pine nuts the tree will yield.[14] The US Department of Agriculture notes that variation in cone production between trees growing on identical sites is often observed.[15]

    American pinyon pine cone production is most commonly found at an elevation between 1,800 and 2,600 m (6,000 and 8,500 ft), and ideally at 2,100 m (7,000 ft). This is due to higher temperatures at elevations lower than 1,800 m (6,000 ft) during the spring, which dry up humidity and moisture content (particularly snow packs) that provide for the tree throughout the spring and summer, causing little nourishment for pine cone maturity.

    Although several other environmental factors determine the conditions of the ecosystem (such as clouds and rain), the trees tend to abort cones without sufficient water. High humidity encourages cone development.[16] There are certain topographical areas found in lower elevations, such as shaded canyons, where the humidity remains constant throughout the spring and summer, allowing pine cones to fully mature and produce seed.

    At elevations above 2,600 m (8,500 ft), the temperature substantially drops, drastically affecting the state of the dormant cone. During the winter, frequent dramatic changes in temperature, drying, and gusty winds make the cones susceptible to freeze-drying that permanently damages them; in this case, growth is stunted, and the seeds deteriorate.[17]

    Physical characteristics

    [edit]

    Korean pine and Armand pine nut distinctions

    When first extracted from the pine cone, they are covered with a hard shell (seed coat), thin in some species and thick in others. The nutrition is stored in the embryo (sporophyte) in the center. Although a nut in the culinary sense, in the botanical sense, pine nuts are seeds; being a gymnosperm, they lack a carpel (fruit) outside.

    The shell must be removed before the pine nut can be eaten. Unshelled pine nuts have a long shelf life if kept dry and refrigerated (−5 to 2 °C or 23 to 36 °F); shelled nuts (and unshelled nuts in warm conditions) deteriorate rapidly, becoming rancid within a few weeks or even days in warm, humid conditions. Pine nuts are commercially available in the shelled form, but due to poor storage, they can have poor flavor and may already be rancid at the time of purchase. Consequently, pine nuts are often frozen to preserve their flavor.[18]

    European pine nuts may be distinguished from Asian ones by their greater length than girth; Asian pine nuts are stubbier, shaped somewhat like long kernels of corn. The American piñon nuts are known for their large size and ease of shelling. In the United States, Pinus edulis, the hard shell of New Mexico and Colorado, became a sought-after species due to the trading post system and the Navajo people who used the nuts as a means of commerce. The Italian pine nut (P. pinea) was brought to the United States by immigrants and became a favored treat along the East Coast in the early 1930s, when bumper crops of American pine nuts were readily available at low prices.

    When dried for eating, pine nuts are 2% water, 13% carbohydrates, 14% protein, and 68% fat (table). In a 100-gram (3+12-ounce) reference serving, dried pine nuts supply 2,815 kilojoules (673 kilocalories) of food energy and are a rich source (20% or more of the Daily Value, DV) of numerous micronutrients, particularly manganese (419% DV), phosphorus (82% DV), magnesium (71% DV), zinc (67% DV), copper (65% DV), vitamin E (62% DV), vitamin K (51% DV), and the B vitaminsthiamin and niacin (29–35% DV), among others (table).

    Culinary uses

    [edit]

    Pine nuts have been eaten in Europe and Asia since the Paleolithic period.[citation needed] They are frequently added to meat, fish, salads, and vegetable dishes or baked into bread.

    In Italian, they are called pinoli (in the US, they are often called pignoli, but in Italy, pignolo is actually a word far more commonly used to describe a fussy, overly fastidious or extremely meticulous person)[21] and are an essential component of Italian pesto sauce; the upsurge in the popularity of this sauce since the 1990s has increased the visibility of the nut in America, primarily on the West Coast. Torta della nonna (literally “granny’s cake”) is a generic Italian dish name that in most families indicates an old family recipe for any cake but often is used for a tart or a pie filled with custard, topped with pine nuts and optionally dusted with icing sugarPignoli cookies, an Italian American specialty confection (in Italy, these would be called biscotti ai pinoli), are made of almond flour formed into a dough similar to that of a macaroon and then topped with pine nuts.

    In Catalonia, a sweet is made of small marzipan balls covered with pine nuts, painted with egg, and lightly cooked, and those are called “panellets”. Pine nuts are also featured in the salade landaise of southwestern France. Nevada, or Great Basin, pine nut has a sweet fruity flavor and is promoted for its large size, sweet flavor, and ease of peeling.

    Pine nuts are also widely used in Levantine cuisine, reflected in a diverse range of dishes such as kibbehsambusakfatayer, and Maqluba, desserts such as baklavameghli, and many others.[22]

    Throughout Europe, the Levant, and West Asia, the pine nuts used are traditionally from Pinus pinea (stone pine).[dubious – discuss] They are easily distinguished from the Asian pine nuts by their more slender shape and more homogeneous flesh. Because of the lower price, Asian pine nuts are also often used, especially in cheaper preparations.

    Pine nut oil is added to foods for flavor.[23]

    Taste disturbances

    [edit]

    Some raw pine nuts can cause pine mouth syndrome, a taste disturbance lasting from a few days to a few weeks after consumption. A bitter, metallic, unpleasant taste is reported. There are no known lasting effects, with the United States Food and Drug Administration reporting that there are “no apparent adverse clinical side effects”.[24] Raw nuts from Pinus armandii, mainly in China, may be the cause of the problem.[25][1] Metallic taste disturbance is typically reported 1–3 days after ingestion, being worse on day two and typically lasting up to two weeks.[24] Cases are self-limited and resolve without treatment.[26][27]

    Food fraud

    [edit]

    In the United States, from 2008 to 2012, some people reported a bitter metallic taste (“pine mouth”) that sometimes lasted for weeks after they ate pine nuts. After an international investigation, the FDA found that some manufacturers substituted a non-food species of pine nuts in place of more expensive edible pine nut species as a form of food fraud.[28]

    Other uses

    [edit]

    Some Native American tribes use the hard outer shell of the pine nut as a bead for decorative purposes in traditional regalia and jewelry. In the Great Basin area of the US, collecting pine nuts is a protected right through state law and treaty.[29]

    In northern California, pine nuts are collected from the grey pine or bull pine. Tribes burn designs into the hard shell, reflecting the same design they use in baskets; however, they are often left blank or burned to blacken. These are more often used in women’s regalia and jewelry.[30]
