Lobo Apple Tree

This article is about the fruit and the tree. For the technology company, see For other uses, see , , and. An apple is a sweet, edible produced by an apple tree Malus pumila. Apple are worldwide, and are the most widely grown species in the. The tree originated in , where its wild ancestor, , is still found today. Apples have been grown for thousands of years in and , and were brought to North America by. Apples have religious and significance in many cultures, including , and. Apple Fruit Flowers Kingdom: Clade: Clade: Clade: Order: Family: Genus: Species: M. Generally apple are propagated by onto , which control the size of the resulting tree. There are more than 7,500 known , resulting in a range of desired characteristics. Different cultivars are bred for various tastes and uses, including , eating raw and production. Trees and fruit are prone to a number of , bacterial and pest problems, which can be controlled by a number of and non-organic means. In 2010, the fruit's was as part of research on disease control and selective breeding in apple production. Worldwide production of apples in 2014 was 84. An apple's side, stem end, and interior The apple is a tree, generally standing 6 to 15 ft 1. When cultivated, the size, shape and branch density are determined by selection and trimming method. The are dark green-colored simple ovals with serrated margins and slightly downy undersides. Apple blossom are produced in spring simultaneously with the budding of the leaves, and are produced on spurs and some long shoots. The fruit matures in late summer or autumn, and cultivars exist with a wide range of sizes. The skin of ripe apples is generally red, yellow, green, pink, or although many bi- or tri-colored cultivars may be found. The skin may also be wholly or partly russeted i. The skin is covered in a protective layer of. The exocarp flesh is generally pale yellowish-white, though pink or yellow exocarps also occur. Wild ancestors Main article: The original wild of Malus pumila was Malus sieversii, found growing wild in the in southern , , , and , China. Cultivation of the species, most likely beginning on the forested flanks of the mountains, progressed over a long period of time and permitted secondary of genes from other species into the open-pollinated seeds. Significant exchange with , the crabapple, resulted in current populations of apples being more related to crabapples than to the more similar progenitor Malus sieversii. In strains without recent admixture the contribution of the latter predominates. Genome In 2010, an Italian-led consortium announced they had sequenced the complete of the apple in collaboration with horticultural genomicists at , using ''. It had about 57,000 genes, the highest number of any plant genome studied to date and more genes than the human genome about 30,000. This new understanding of the apple genome will help scientists in identifying genes and gene variants that contribute to resistance to disease and drought, and other desirable characteristics. Understanding the genes behind these characteristics will allow scientists to perform more knowledgeable selective breeding. The genome sequence also provided proof that Malus sieversii was the wild ancestor of the domestic apple—an issue that had been long-debated in the scientific community. Wild Malus sieversii apple in The center of diversity of the genus is in eastern present-day. The apple tree was perhaps the earliest tree to be cultivated, and its fruits have been improved through selection over thousands of years. Winter apples, picked in late autumn and stored just above freezing, have been an important food in Asia and Europe for millennia. Of the many Old World plants that the Spanish introduced to in the , apple trees became particularly well adapted. Apples were introduced to North America by colonists in the , and the first apple orchard on the North American continent was planted in by Reverend in 1625. Apple cultivars brought as seed from Europe were spread along Native American trade routes, as well as being cultivated on colonial farms. In the 20th century, irrigation projects in began and allowed the development of the multibillion-dollar fruit industry, of which the apple is the leading product. Until the 20th century, farmers stored apples in during the winter for their own use or for sale. Improved transportation of fresh apples by train and road replaced the necessity for storage. Controlled atmosphere facilities use high humidity, low oxygen, and controlled carbon dioxide levels to maintain fruit freshness. They were first used in the United States in the 1960s. English scholar links apples to religious practices in , from which developed. She points out that buckets of apples were found in the burial site in Norway, and that fruit and nuts Iðunn having been described as being transformed into a nut in have been found in the early graves of the in England and elsewhere on the continent of Europe, which may have had a symbolic meaning, and that nuts are still a recognized symbol of in southwest England. Davidson also notes a further connection between fertility and apples in Norse mythology in chapter 2 of the when the major goddess sends King an apple after he prays to Odin for a child, Frigg's messenger in the guise of a crow drops the apple in his lap as he sits atop a. Rerir's wife's consumption of the apple results in a six-year pregnancy and the birth of their son—the hero. She states this may imply that the apple was thought of by Brúnarson as the food of the dead. Further, Davidson notes that the potentially Germanic goddess is sometimes depicted with apples and that parallels exist in early Irish stories. Davidson asserts that while cultivation of the apple in Northern Europe extends back to at least the time of the and came to Europe from the , the native varieties of apple trees growing in Northern Europe are small and bitter. For instance, in , the , as a part of his , was required to travel to the Garden of the Hesperides and pick the golden apples off the growing at its center. The Greek goddess of discord, , became disgruntled after she was excluded from the wedding of and. Three goddesses claimed the apple: , , and. After being bribed by both Hera and Athena, Aphrodite tempted him with the most beautiful woman in the world, of. He awarded the apple to Aphrodite, thus indirectly causing the. The apple was thus considered, in ancient Greece, to be sacred to Aphrodite, and to throw an apple at someone was to symbolically declare one's love; and similarly, to catch it was to symbolically show one's acceptance of that love. An epigram claiming authorship by Plato states: I throw the apple at you, and if you are willing to love me, take it and share your girlhood with me; but if your thoughts are what I pray they are not, even then take it, and consider how short-lived is beauty. Hippomenes knew that he could not win in a fair race, so he used three golden apples gifts of Aphrodite, the goddess of love to distract Atalanta. It took all three apples and all of his speed, but Hippomenes was finally successful, winning the race and Atalanta's hand. Christian art by 1507 , showcasing the apple as a symbol of sin. Though the forbidden fruit of in the is not identified, popular Christian tradition has held that it was an apple that coaxed to share with her. The origin of the popular identification with a fruit unknown in the Middle East in biblical times is found in confusion between the words mālum an apple and mălum an evil , each of which is normally written malum. As a result, in the story of Adam and Eve, the apple became a symbol for knowledge, immortality, temptation, the fall of man into sin, and sin itself. The apple as symbol of sexual has been used to imply human sexuality, possibly in an ironic vein. Main article: There are more than 7,500 known of apples. Cultivars vary in their and the ultimate size of the tree, even when grown on the same. Different cultivars are available for and climates. The UK's National Fruit Collection, which is the responsibility of the Department of Environment Food and Rural Affairs, includes a collection of over 2,000 cultivars of apple tree in Kent. The University of Reading, which is responsible for developing the UK national collection database, provides access to search the national collection. Most of these cultivars are bred for eating fresh dessert apples , though some are cultivated specifically for cooking or producing. Commercially popular apple cultivars are soft but crisp. Other desired qualities in modern commercial apple breeding are a colorful skin, absence of , ease of shipping, lengthy storage ability, high yields, disease resistance, common apple shape, and developed flavor. Modern apples are generally sweeter than older cultivars, as popular tastes in apples have varied over time. Most North Americans and Europeans favor sweet, subacid apples, but tart apples have a strong minority following. Extremely sweet apples with barely any acid flavor are popular in Asia and especially. Old cultivars are often oddly shaped, russeted, and have a variety of textures and colors. A few old cultivars are still produced on a large scale, but many have been preserved by home gardeners and farmers that sell directly to local markets. Many unusual and locally important cultivars with their own unique taste and appearance exist; apple conservation campaigns have sprung up around the world to preserve such local cultivars from extinction. In the United Kingdom, old cultivars such as '' and '' are still commercially important even though by modern standards they are low yielding and susceptible to disease. However, more than with most perennial fruits, apples must be propagated asexually by to obtain the sweetness and other desirable characteristics of the parent. Even in the case when a triploid plant can produce a seed apples are an example , it occurs infrequently, and seedlings rarely survive. Because apples do not when planted as seeds, is generally used to produce new apple trees. The used for the bottom of the graft can be selected to produce trees of a large variety of sizes, as well as changing the winter hardiness, insect and disease resistance, and soil preference of the resulting tree. Dwarf rootstocks can be used to produce very small trees less than 3. Dwarf rootstocks for apple trees can be traced as far back as 300 BC, to the area of and. Dwarf rootstocks became common by the 15th century, and later went through several cycles of popularity and decline throughout the world. The majority of the rootstocks used today to control size in apples were developed in England in the early 1900s. Most new apple cultivars originate as seedlings, which either arise by chance or are bred by deliberately crossing cultivars with promising characteristics. Apples can also form mutations on a single branch. Some bud sports turn out to be improved strains of the parent cultivar. Some differ sufficiently from the parent tree to be considered new cultivars. Since the 1930s, the Excelsior Experiment Station at the has introduced a steady progression of important apples that are widely grown, both commercially and by local orchardists, throughout and. Its most important contributions have included '' which is the most widely cultivated apple in Minnesota , '', 'Honeygold', and ''. Apples have been acclimatized in Ecuador at very high altitudes, where they can often, with the needed factors, provide crops twice per year because of constant temperate conditions year-round. Pollination on apple bloom, , Canada Apples are self-incompatible; they must to develop fruit. During the flowering each season, apple growers often utilize to carry pollen. Cultivars are sometimes classified by the day of peak bloom in the average 30-day blossom period, with pollenizers selected from cultivars within a 6-day overlap period. Maturation and harvest See also: and Cultivars vary in their yield and the ultimate size of the tree, even when grown on the same rootstock. Some cultivars, if left unpruned, will grow very large, which allows them to bear much more fruit, but makes harvesting very difficult. Depending on the tree density number of trees planted per unit surface area , mature trees typically bear 40—200 kg 90—440 lb of apples each year, though productivity can be close to zero in poor years. Apples are harvested using three-point ladders that are designed to fit amongst the branches. Trees grafted on dwarfing rootstocks will bear about 10—80 kg 20—180 lb of fruit per year. Farms with apple orchards may open them to the public, so consumers may themselves pick the apples they will purchase. Crops ripen at different times of the year according to the cultivar. Cultivar that yield their crop in the summer include 'Gala', 'Golden Supreme', 'McIntosh', 'Transparent', 'Primate', '', and 'Duchess'; fall producers include 'Fuji', 'Jonagold', 'Golden Delicious', 'Red Delicious', 'Chenango', 'Gravenstein', 'Wealthy', 'McIntosh', 'Snow', and 'Blenheim'; winter producers include 'Winesap', 'Granny Smith', 'King', 'Wagener', '', 'Greening', and 'Tolman Sweet'. Storage Different kinds of apple in a wholesale food market Commercially, apples can be stored for some months in chambers to delay -induced ripening. Apples are commonly stored in chambers with higher concentrations of and high air filtration. This prevents ethylene concentrations from rising to higher amounts and preventing ripening from occurring too quickly. For home storage, most cultivars of apple can be held for approximately two weeks when kept at the coolest part of the refrigerator i. Some can be stored up to a year without significant degradation. Non-organic apples may be sprayed with blocking the apples' ethylene receptors, temporarily preventing them from ripening. Pests and diseases See also: Apple trees are susceptible to a number of and diseases and insect pests. Many commercial orchards pursue a program of chemical sprays to maintain high fruit quality, tree health, and high yields. These prohibit the use of synthetic pesticides, though some older pesticides are allowed. The flowers will turn a creamy yellow color and will not develop correctly. This can be treated in a manner not dissimilar from treating ; eliminating the conditions which caused the disease in the first place and burning the infected plants are among the recommended actions to take. The aphid species can be identified by their color, the time of year when they are present and by differences in the cornicles, which are small paired projections from the rear of aphids. Aphids feed on foliage using needle-like mouth parts to suck out plant juices. When present in high numbers, certain species reduce tree growth and vigor. The disease also affects the fruit, which also develops similar brown spots with velvety or cork-like textures. Apple scab is spread through fungus growing in old apple leaves on the ground and spreads during warm spring weather to infect the new year's growth. Among the most serious disease problems are , a bacterial disease; and rust, and , two fungal diseases. Young apple trees are also prone to mammal pests like mice and deer, which feed on the soft bark of the trees, especially in winter. The larvae of the burrow through the bark and into the phloem of apple trees, potentially causing significant damage. An apple core, part of an apple not usually eaten, containing the seeds All parts of the fruit, including the skin, except for the seeds, are suitable for human consumption. The core, from stem to bottom, containing the seeds, is usually not eaten and is discarded. Apples can be consumed various ways: , raw in salads, baked in , cooked into and spreads like , and other. Several techniques are used to preserve apples and apple products. Apples can be canned, dried or frozen. Canned or frozen apples are eventually baked into pies or other cooked dishes. Apple juice or cider is also bottled. Apple juice is often concentrated and frozen. Popular uses Apples are often eaten raw. Cultivars bred for raw consumption are termed dessert or. Similar treats in the U. Apples are an important ingredient in many desserts, such as , apple , and. When cooked, some apple cultivars easily form a puree known as. Apples are also made into and apple jelly. They are often or and are also cooked in some meat dishes. Dried apples can be eaten or reconstituted soaked in water, alcohol or some other liquid. Apples are milled or pressed to produce , which may be drunk unfiltered called in North America , or filtered. Filtered juice is often concentrated and frozen to be reconstituted later and consumed. Apple juice can be to make called hard cider in North America , , and vinegar. Through , various alcoholic beverages can be produced, such as , , and. Sliced apples turn brown with exposure to air due to the conversion of natural phenolic substances into upon exposure to. Different cultivars vary in their propensity to brown after slicing and the do not brown. Sliced fruit can be treated with to prevent this effect. Sliced apple consumption tripled in the US from 2004 to 2014 to 500 million apples annually due to its convenience. Organic production apples are commonly produced in the United States. Due to infestations by key insects and diseases, organic production is difficult in Europe. The use of pesticides containing chemicals, such as sulfur, copper, microorganisms, viruses, clay powders, or plant extracts , has been approved by the EU Organic Standing Committee to improve organic yield and quality. A light coating of , which forms a physical barrier to some pests, also may help prevent apple sun scalding. Phytochemicals Apples are a rich source of various including e. Phenolic compounds, such as polyphenol oxidase, are the main driving force behind browning in apples. Polyphenol oxidase catalyzes the reaction of phenolic compounds to o-quinones causing the pigment to turn darker and therefore brown. Other products and can be produced. Allergy One form of apple allergy, often found in northern Europe, is called birch-apple syndrome, and is found in people who are also allergic to. Allergic reactions are triggered by a protein in apples that is similar to birch pollen, and people affected by this protein can also develop allergies to other fruits, nuts, and vegetables. Reactions, which entail OAS , generally involve itching and inflammation of the mouth and throat, but in rare cases can also include life-threatening. This reaction only occurs when raw fruit is consumed—the allergen is neutralized in the cooking process. The variety of apple, maturity and storage conditions can change the amount of allergen present in individual fruits. Long storage times can increase the amount of proteins that cause birch-apple syndrome. In other areas, such as the Mediterranean, some individuals have adverse reactions to apples because of their similarity to peaches. This form of apple allergy also includes OAS, but often has more severe symptoms, such as vomiting, abdominal pain and , and can be life-threatening. Individuals with this form of allergy can also develop reactions to other fruits and nuts. Cooking does not break down the protein causing this particular reaction, so affected individuals can eat neither raw nor cooked apples. Freshly harvested, over-ripe fruits tend to have the highest levels of the protein that causes this reaction. Breeding efforts have yet to produce a fruit suitable for either of the two forms of apple allergy. Toxicity of seeds The seeds of apples contain small amounts of , a sugar and compound known as a. Ingesting small amounts of apple seeds will cause no ill effects, but consumption of extremely large doses can cause. It may take several hours before the poison takes effect, as cyanogenic glycosides must be before the cyanide ion is released. The United States 's records no cases of amygdalin poisoning from consuming apple seeds. In Flora of North America Editorial Committee.
