The second major step in the development of pecan was a change from wind-dispersed fruits to animal dispersion. [14] Commercial growers are most concerned with the ABI, which describes a cultivar's likelihood to bear on alternating years (index of 1.0 signifies highest likelihood of bearing little to nothing every other year). Since pecan production is limited in the northern states, this is a perfect choice if you live up north and wish to plant a pecan tree… Pecan genus and other classification is necessary information to know for every botanist. As the common name implies, Carya illinoinensis is the tree responsible for producing Pecan nuts commonly used in snacks and cooking recipes, and is the state tree of Texas. Pecan trees are wind pollinated. Cultivar selection is the most important factor in purchasing pecan trees. This was accomplished by a slave called Antoine in 1846 or 1847, who was owned by Jacques Telesphore Roman of the Oak Alley Plantation near the Mississippi river. The pecan (Carya illinoinensis) is a species of hickory native to northern Mexico and the southern United States in the region of the Mississippi River. [6] The most common American pronunciation is /pɪˈkɑːn/. The outer husk is 3–4 mm (1⁄8–5⁄32 in) thick, starts out green and turns brown at maturity, at which time it splits off in four sections to release the thin-shelled seed. We have compiled a collection of pecan pictures for your viewing pleasure. In the Southeastern United States, nickel deficiency in C. illinoinensis produces a disorder called mouse-ear in trees fertilized with urea. Scab is currently the most destructive disease affecting pecan trees untreated with fungicides. Pecan tree fun facts: The Pecan is the State Tree of Texas. Pecan trees originated in central and eastern North America. The common name of this plant in Spanish is Carya illinoinensis. The pecan tree is prevalent in Louisiana as a shade tree in the landscape and also as a source of nuts for home use.

Pecan, (Carya illinoinensis), nut and tree of the walnut family (Juglandaceae) native to temperate North America. Most native or “wild” pecans have been known to have thicker shells and smaller nuts than improved varieties. Plant growth and development resemble a forest tree species rather than a domesticated crop. Most such hybrids are unproductive. Extant examples of Engelhardioideae are generally tropical and evergreen, while those of Juglandioideae are deciduous and found in more temperate zones. If you are planting an orchard, you need to know the eventual height and width of your chosen varieties so the trees are not crowded. & Graebn. Commercial production of pecans was slow because trees are slow to mature and bear fruit. The crops of sweet nuts are abundant and contine regardless of age. A seeping pecan tree is more than likely afflicted with pecan tree aphids. [40] In 1988, Oklahoma enacted an official state meal which included pecan pie.[41]. Pecan fat content consists principally of monounsaturated fatty acids, mainly oleic acid (57% of total fat), and the polyunsaturated fatty acid, linoleic acid (30% of total fat). It responds well to release in all age groups, provided that the trees have good vigor. Nuts are large, of … By the 1700s, American settlers were cultivating pecans, and a pecan export business soon followed. [7], The pecan tree is a large deciduous tree, growing to 20–40 m (66–131 ft) in height, rarely to 44 m (144 ft).

Scientific name is the name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN). Pecan Genus and Other Classification Genus is a group of plants which are related to each other in some or the other way. More importantly, the trees grown from nuts of one tree have very diverse characters. The husks are produced from the exocarp tissue of the flower, while the part known as the nut develops from the endocarp and contains the seed. The Spaniards took the pecan into Europe, Asia, and Africa beginning in the 16th century. These include ambrosia beetles, twig girdlers, pecan nut casebearer, hickory shuckworm, phylloxera, curculio, weevils, and several aphid species. Various other disorders are documented, including canker disease and shuck decline complex. New varieties of pecan trees were introduced when the practice of grafting together two trees with superior characteristics gained popularity in the 1800s. [5] There are many variant pronunciations, some regional and others not. Varieties adapted from the southern tier of states north through some parts of Iowa and even into southern Canada are available from nurseries. [29], A pecan nut is 4% water, 72% fat, 9% protein, and 14% carbohydrates (table). In a 100 g reference amount, pecans provide 691 Calories and a rich source (20% or more of the Daily Value, DV) of total fat, protein, dietary fiber (38% DV), manganese (214% DV), magnesium (34% DV), phosphorus (40% DV), zinc (48% DV), and thiamin (57% DV) (table). Collingwood, G. H., Brush, W. D., & Butches, D., eds. [1] The tree is cultivated for its seed in the southern United States, primarily in Georgia,[2] New Mexico,[3] and Texas,[4] and in Mexico, which produces nearly half of the world total. Pecan trees grow wild in the United States and also are cultivated widely for their fruit, the pecan nut, and wood with its beautiful grain. The ratio of oleic to linoleic acids are inverted between wind- and animal-dispersed seeds. The pecan tree is native to North America, and most pecan tree varieties grow well from Illinois down to Florida and across the south to Texas. By the 1700s, American settlers were cultivating pecans, and a pecan export business soon followed. The husks of walnuts develop from the bracts, bracteoles, and sepals, or sepals only. The nut harvest for growers is typically around mid-October. In North Carolina, pecan … Pecan tree varieties known for stronger branches are more desirable for planting in a landscape because they require less maintenance. Numerous varieties produce well in Texas, but fail in the Southeastern U.S. due to increased disease pressure. Open grown pecan trees have massive trunks and oval or rounded wide spreading crowns of branches that extend far down the trunk. Hybrids are referred to as "hicans" to indicate their hybrid origin. To speed nut production and retain the best tree characteristics, grafting from mature productive trees was the obvious strategy. Your climate plays an important role in whether a pecan tree will be successful. The nuts, or pecans, are produced during the summer and fall from the tree in the autumn. Because of their familiarity with the genus Juglans, these early explorers referred to the nuts as nogales and nueces, the Spanish terms for "walnut trees" and "fruit of the walnut". The scientific name of Pecan is the botanical name or formal name. There is little agreement in the United States, even regionally, as to the "correct" pronunciation. Pecan trees grow to 180 feet tall with large trunks up to 6 feet in diameter.

CAPE26: Carya pecan (Marshall) Engl. Make sure the hardiness zone range of the tree you choose includes your area. Facts about pecan trees may surprise and even astonish you. The seeds of the pecan are edible, with a rich, buttery flavor. Thomas Jefferson planted pecan trees, C. illinoinensis (Illinois nuts), in his nut orchard at his home, Monticello, in Virginia. Native American tribes harvested wild pecans and were the first to cultivate pecan trees. All trees produce both male and female flowers but not at the same time. Pecan trees are not only grown for nut production in large orchards, but also in landscapes for their attractive shape and dense shade. While selection work has been done since the late 19th century, most acreage of pecans grown today is of older cultivars, such as 'Stuart', 'Schley', 'Elliott', and 'Desirable', with known flaws but also with known production potential. Varieties of pecan trees that are protogynous, or flowering first, are Wichita, Kiowa, Elliot, Curtis, Burkett and Candy. [24] The long cycle time for pecan trees plus financial considerations dictate that new varieties go through an extensive vetting process before being widely planted. [citation needed]. They noted the particularly thin shell and acorn-like shape of the fruit, indicating they were indeed referring to pecans. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, and Texas, and in Mexico, which produces nearly half of the world total. On older trees, the bark forms large, flattened, scale-like patches. They are very similar to the Elliott pecans, in that it has great oil content, tastes delicious, and make perfect halves. A 10-year-old sapling grown in optimal conditions will stand about 5 m (16 ft) tall. Trunks mature to 2-4’ in diameter.

Although wild pecans were well known among native and colonial Americans as a delicacy, the commercial growing of pecans in the United States did not begin until the 1880s. [14], Choosing cultivars can be a complex practice, based on the Alternate Bearing Index (ABI) and their period of pollinating. Pecan trees originated in central and eastern North America. However, many plantings do not produce because of poor variety, poor site selection, lack of fertilization, or poor insect and disease control. The pecan is a large tree with a narrow, pyramid-shaped crown in the forest, and a broad and rounded crown in the open.

Pecan tree varieties known for stronger branches are more desirable for planting in a landscape because they require less maintenance. Pecan is a subclimax species [11,18]. These Spanish explorers called the pecan, nuez de la arruga, which roughly translates to "wrinkle nut". Includes extensive resources on pecan growth and pest … Other tree species employing a strong taproot system include hickory, walnut, butternut, white oak and hornbeam. These range from scab to hickory shuckworm to shuck decline. Stuart. Look for trees with cold tolerance and insect and disease resistance. This dispersal strategy coincides with the development of a husk around the fruit and a drastic change in the relative concentrations of fatty acids.

The nuts, known as pecans, are a frequent addition to baked goods and desserts. Differentiation between the subfamilies of Engelhardioideae and Juglandioideae occurred during the early Paleogene, about 64 million years ago. Non-grafted seedlings and native Pecan trees often take 10 to 15 years to begin to produce fruit. [16][17], Native pecans in Mexico are adapted from zone 9 to zone 11. We also offer some varieties that are hardy enough be grown successfully in cooler climates as far north as the upper Midwest (Zones 5-6). Pollination is the exchange of pollen between trees to fertilize the flowers so the tree can produce pecans.
