<p>The <b>avocado</b> (<i>Persea americana</i>) is a tree, long thought to have originated in South Central Mexico,<span style="font-size: xx-small;"> </span>classified as a member of the flowering plant family Lauraceae. The fruit of the plant, also called an avocado (or <b>avocado pear</b> or <b>alligator pear</b>), is botanically a large berry containing a single large seed.</p>
<p>Avocados are commercially valuable and are cultivated in tropical and Mediterranean climates throughout the world.<sup id="cite_ref-morton_4-1" class="reference">[4]</sup> They have a green-skinned, fleshy body that may be pear-shaped, egg-shaped, or spherical. Commercially, they ripen after harvesting. Avocado trees are partially self-pollinating and are often propagated through grafting to maintain a predictable quality and quantity of the fruit.</p>

<h2><span class="mw-headline" id="Etymology">Etymology</span></h2>
<p>The word "avocado" comes from the Spanish <i title="Spanish language text" xml:lang="es" lang="es">aguacate</i>, which in turn comes from the Nahuatl word <i title="Classical Nahuatl language text" xml:lang="nci" lang="nci">āhuacatl</i> <small></small><span title="Representation in the International Phonetic Alphabet (IPA)" class="IPA">[aːˈwakat͡ɬ]</span>,<sup id="cite_ref-22" class="reference">[21]</sup> which goes back to the proto-Aztecan *<i title="Nahuatl languages collective text" xml:lang="nah" lang="nah">pa:wa</i> which also meant "avocado".<sup id="cite_ref-23" class="reference">[22]</sup> Sometimes the Nahuatl word was used with the meaning "testicle", probably because of the likeness between the fruit and the body part.<sup id="cite_ref-24" class="reference">[23]</sup></p>
<p>The modern English name comes from an English rendering of the Spanish <i title="Spanish language text" xml:lang="es" lang="es">aguacate</i> as <i title="Spanish language text" xml:lang="es" lang="es">avogato</i>. The earliest known written use in English is attested from 1697 as "avogato pear", a term which was later corrupted as "alligator pear".<sup id="cite_ref-25" class="reference">[24]</sup> Because the word <i title="Spanish language text" xml:lang="es" lang="es">avogato</i> sounded like "advocate", several languages reinterpreted it to have that meaning. French uses <i title="French language text" xml:lang="fr" lang="fr">avocat</i>, which also means <i>lawyer</i>, and "advocate" — forms of the word appear in several Germanic languages, such as the (now obsolete) German <i title="German language text" xml:lang="de" lang="de">Advogato-Birne</i>, the old Danish <i title="Danish language text" xml:lang="da" lang="da">advokat-pære</i> (today it is called <i title="Danish language text" xml:lang="da" lang="da">avocado</i>) and the Dutch <i title="Dutch language text" xml:lang="nl" lang="nl">advocaatpeer</i>.<sup id="cite_ref-26" class="reference">[25]</sup></p>
<h3><span class="mw-headline" id="Regional_names">Regional names</span></h3>
<p>In other Central American and Caribbean Spanish-speaking countries, it is known by the Mexican name, while South American Spanish-speaking countries use a Quechua-derived word, <i title="Spanish language text" xml:lang="es-419" lang="es-419">palta</i>. In Portuguese, it is <i title="Portuguese language text" xml:lang="pt" lang="pt">abacate</i>. The fruit is sometimes called an <i>avocado pear</i> or <i>alligator pear</i> (due to its shape and the rough green skin of some cultivars).<sup id="cite_ref-morton_4-3" class="reference">[4]</sup> The Nahuatl <i title="Nahuatl languages collective text" xml:lang="nah" lang="nah">āhuacatl</i> can be compounded with other words, as in <i title="Nahuatl languages collective text" xml:lang="nah" lang="nah">ahuacamolli</i>, meaning avocado soup or sauce, from which the Spanish word <i title="Spanish language text" xml:lang="es" lang="es">guacamole</i> derives.<sup id="cite_ref-27" class="reference">[26]</sup></p>

<h2><span class="mw-headline" id="Cultivation">Cultivation</span></h2>
<p>The subtropical species needs a climate without frost and with little wind. High winds reduce the humidity, dehydrate the flowers, and affect pollination. When even a mild frost occurs, premature fruit drop may occur, although the 'Hass' cultivar can tolerate temperatures down to −1 °C. Several cold-hardy varieties are planted in the region of Gainesville, Florida, which survive temperatures as low as −6.5 °C (20 °F) with only minor leaf damage. The trees also need well-aerated soils, ideally more than 1 m deep. Yield is reduced when the irrigation water is highly saline. These soil and climate conditions are available in southern and eastern Spain, Morocco, the Levant, South Africa, Venezuela, Colombia, Peru, parts of central and northern Chile, Vietnam, Indonesia, parts of southern India, Sri Lanka, Australia, New Zealand, the Philippines, Malaysia, Central America, the Caribbean, Mexico, southern California, Arizona, Puerto Rico, Texas, Florida, Hawaii, Ecuador, and Rwanda. Each region has different cultivars.<sup class="noprint Inline-Template Template-Fact">[<i><span title="This claim needs references to reliable sources.

<h3><span class="mw-headline" id="Harvest_and_postharvest">Harvest and postharvest</span></h3>
<p>Commercial orchards produce an average of seven tonnes per hectare each year, with some orchards achieving 20 tonnes per hectare.<sup id="cite_ref-30" class="reference">[29]</sup> Biennial bearing can be a problem, with heavy crops in one year being followed by poor yields the next.</p>
<p>Like the banana, the avocado is a climacteric fruit, which matures on the tree, but ripens off the tree. Avocados used in commerce are picked hard and green and kept in coolers at 3.3 to 5.6 °C (37.9 to 42.1 °F) until they reach their final destination. Avocados must be mature to ripen properly. Avocados that fall off the tree ripen on the ground. Generally, the fruit is picked once it reaches maturity; Mexican growers pick 'Hass' avocados when they have more than 23% dry matter, and other producing countries have similar standards. Once picked, avocados ripen in one to two weeks (depending on the cultivar) at room temperature (faster if stored with other fruits such as apples or bananas, because of the influence of ethylene gas). Some supermarkets sell ripened avocados which have been treated with synthetic ethylene to hasten ripening.<sup id="cite_ref-31" class="reference">[30]</sup> The use of an ethylene gas "ripening room", which is now an industry standard, was pioneered in the 1980s by farmer Gil Henry of Escondido, California, in response to footage from a hidden supermarket camera which showed shoppers repeatedly squeezing hard, unripe avocados, putting them "back in the bin," and moving on without making a purchase.<sup id="cite_ref-32" class="reference">[31]</sup> In some cases, avocados can be left on the tree for several months, which is an advantage to commercial growers who seek the greatest return for their crop, but if the fruit remains unpicked for too long, it falls to the ground.</p>

<p>The species is only partially able to self-pollinate because of dichogamy in its flowering. This limitation, added to the long juvenile period, makes the species difficult to breed. Most cultivars are propagated by grafting, having originated from random seedling plants or minor mutations derived from cultivars. Modern breeding programs tend to use isolation plots where the chances of cross-pollination are reduced. That is the case for programs at the University of California, Riverside, as well as the Volcani Centre and the Instituto de Investigaciones Agropecuarias in Chile.</p>
<p>The avocado is unusual in that the timing of the male and female flower phases differs among cultivars. The two flowering types are A and B. A-cultivar flowers open as female on the morning of the first day and close in late morning or early afternoon. Then they open as male in the afternoon of the second day. B varieties open as female on the afternoon of the first day, close in late afternoon and reopen as male the following morning.</p>
<ul>
<li>A cultivars: 'Hass', 'Gwen', 'Lamb Hass', 'Pinkerton', 'Reed'</li>
<li>B cultivars: 'Fuerte', 'Sharwil', 'Zutano', 'Bacon', 'Ettinger', 'Sir Prize', 'Walter Hole'<sup id="cite_ref-33" class="reference">[32]</sup><sup id="cite_ref-34" class="reference">[33]</sup></li>
</ul>
<p>Certain cultivars, such as the 'Hass', have a tendency to bear well only in alternate years. After a season with a low yield, due to factors such as cold (which the avocado does not tolerate well), the trees tend to produce abundantly the next season. In addition, due to environmental circumstances during some years, seedless avocados may appear on the trees.<sup id="cite_ref-35" class="reference">[34]</sup> Known in the avocado industry as "cukes", they are usually discarded commercially due to their small size.<sup id="cite_ref-36" class="reference">[35]</sup></p>

<p>Avocados can be propagated by seed, taking roughly four to six years to bear fruit, although in some cases seedlings can take 10 years to come into bearing.<sup id="cite_ref-37" class="reference">[36]</sup> The offspring is unlikely to be identical to the parent cultivar in fruit quality. Prime quality varieties are therefore propagated by grafting to rootstocks that are propagated by seed (seedling rootstocks) or by layering (clonal rootstocks). After about a year of growing in a greenhouse, the young rootstocks are ready to be grafted. Terminal and lateral grafting is normally used. The scion cultivar grows for another 6–12 months before the tree is ready to be sold. Clonal rootstocks are selected for tolerance of specific soil and disease conditions, such as poor soil aeration or resistance to the soil-borne disease (root rot) caused by <i>Phytophthora</i>.</p>
<p>Commercial avocado production is limited to a small fraction of the vast genetic diversity in the species. Conservation of this genetic diversity has relied largely on field collection, as avocado seeds often do not survive storage in seed banks. This is problematic, as field preservation of living cultivars is expensive, and habitat loss threatens wild cultivars. More recently, an alternate method of conservation has been developed based on cryopreservation of avocado somatic embryos with reliable methods for somatic embryogenesis and reconstitution into living trees.<sup id="cite_ref-38" class="reference">[37]</sup></p>
<h3><span class="mw-headline" id="Growing_indoors">Growing indoors</span></h3>
<p>Indoors, an avocado tree is usually grown from the pit of an avocado fruit. This is often done by removing the pit from a ripe, unrefrigerated avocado fruit. The pit is then stabbed with three or four toothpicks, about one-third of the way up from the flat end. The pit is placed in a jar or vase containing tepid water. It should split in four to six weeks and yield roots and a sprout. If there is no change by this time, the avocado pit is discarded. Once the stem has grown a few inches, it is placed in a pot with soil. It should be watered every few days. Avocados have been known to grow large, so owners must be ready to re-pot the plant several times.</p>

<p>The avocado tree can be grown domestically and used as a (decorative) houseplant. The pit germinates in normal soil conditions or partially submerged in a small glass (or container) of water. In the latter method, the pit sprouts in four to six weeks, at which time it is planted in standard houseplant potting soil. The plant normally grows large enough to be prunable; it does not bear fruit unless it has ample sunlight. Home gardeners can graft a branch from a fruit-bearing plant to speed maturity, which typically takes four to six years to bear fruit.<sup id="cite_ref-72" class="reference"></sup></p>
