The pineapple (Ananas comosus) is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae.

The pineapple is indigenous to South America, where it has been cultivated for many centuries. The introduction of the pineapple to Europe in the 17th century made it a significant cultural icon of luxury. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations.

Pineapples grow as a small shrub; the individual flowers of the unpollinated plant fuse to form a multiple fruit. The plant normally propagates from the offset produced at the top of the fruit or from a side shoot, and typically matures within a year

History

Etymology

The first reference in English to the pineapple fruit was the 1568 translation from the French of André Thevet’s The New Found World, or Antarctike where he refers to a Hoyriri, a fruit cultivated and eaten by the Tupinambá people, living near modern Rio de Janeiro, and now believed to be a pineapple. Later in the same English translation, he describes the same fruit as a “Nana made in the manner of a Pine apple”, where he used another Tupi word nanas, meaning ‘excellent fruit’. This usage was adopted by many European languages and led to the plant’s scientific binomial Ananas comosus, where comosus ‘tufted’, refers to the stem of the plant. Purchas, writing in English in 1613, referred to the fruit as Ananas, but the Oxford English Dictionary’s first record of the word pineapple itself by an English writer is by Mandeville in 1714

Precolonial cultivation

The wild plant originates from the Paraná–Paraguay River drainages between southern Brazil and Paraguay. Little is known about its domestication, but it spread as a crop throughout South America. Archaeological evidence of use is found as far back as 1200 – 800 BC (3200–2800 BP) in Peru and 200BC – AD700 (2200–1300 BP) in Mexico, where it was cultivated by the Mayas and the Aztecs. By the late 1400s, cropped pineapple was widely distributed and a staple food of Native Americans. The first European to encounter the pineapple was Columbus, in Guadeloupe on 4 November 1493. The Portuguese took the fruit from Brazil and introduced it into India by 1550. The ‘Red Spanish [es]’ cultivar was also introduced by the Spanish from Latin America to the Philippines, and it was grown for textile use from at least the 17th century.

Columbus brought the plant back to Spain and called it piña de Indes, meaning “pine of the Indians”. The pineapple was documented in Peter Martyr’s Decades of the New World (1516) and Antonio Pigafetta’s Relazione del primo viaggio intorno al mondo (1524-1525), and the first known illustration was in Oviedo’s Historia General de Las Indias (1535)

Old World introduction

The pineapple fascinated Europeans as a fruit of colonialism. But it was not successfully cultivated in Europe until Pieter de la Court developed greenhouse horticulture near Leiden from about 1658. Pineapple plants were distributed from the Netherlands to English gardeners in 1719 and French ones in 1730. In England, the first pineapple was grown at Dorney Court, Dorney in Buckinghamshire, and a huge “pineapple stove” to heat the plants was built at the Chelsea Physic Garden in 1723. In France, King Louis XV was presented with a pineapple that had been grown at Versailles in 1733. In Russia, Peter the Great imported de le Court’s method into St. Petersburg in the 1720s; in 1730, 20 pineapple saplings were transported from there to a greenhouse at Empress Anna’s new Moscow palace.

Because of the expense of direct import and the enormous cost in equipment and labour required to grow them in a temperate climate, in greenhouses called “pineries”, pineapple became a symbol of wealth. They were initially used mainly for display at dinner parties, rather than being eaten, and were used again and again until they began to rot. In the second half of the 18th century, the production of the fruit on British estates became the subject of great rivalry between wealthy aristocrats. John Murray, 4th Earl of Dunmore, built a hothouse on his estate surmounted by a huge stone cupola 14 metres tall in the shape of the fruit; it is known as the Dunmore Pineapple. In architecture, pineapple figures became decorative elements symbolizing hospitality.

Since 19th century: mass commercialization

Many different varieties, mostly from the Antilles, were tried for European glasshouse cultivation. The most significant was “Smooth Cayenne”, imported to France in 1820, subsequently re-exported to the United Kingdom in 1835, and then from the UK via Hawaii `to Australia and Africa. “Smooth Cayenne” is now the dominant cultivar in world production. Jams and sweets based on pineapple were imported to Europe from the West Indies, Brazil, and Mexico from an early date. By the early 19th century, fresh pineapples were transported direct from the West Indies in large enough quantities to reduce European prices. Later pineapple production was dominated by the Azores for Europe, and Florida and the Caribbean for North America, because of the short trade routes.

The Spanish had introduced the pineapple into Hawaii in the 18th century where it is known as the hala kahiki (“foreign hala”), but the first commercial plantation was established in 1886. The most famous investor was James Dole, who moved to Hawaii in 1899 and started a 24-hectare (60-acre) pineapple plantation in 1900 which would grow into the Dole Food Company. Dole and Del Monte began growing pineapples on the island of Oahu in 1901 and 1917, respectively, and the Maui Pineapple Company began cultivation on Maui in 1909. James Dole began the commercial processing of pineapple, and Dole employee Henry Ginaca invented an automatic peeling and coring machine in 1911.

Hawaiian production started to decline from the 1970s because of competition and the shift to refrigerated sea transport. Dole ceased its cannery operations in Honolulu in 1991, and in 2008, Del Monte terminated its pineapple-growing operations in Hawaii. In 2009, the Maui Pineapple Company reduced its operations to supply pineapples only locally on Maui, and by 2013, only the Dole Plantation on Oahu grew pineapples in a volume of about 0.1 percent of the world’s production. Despite this decline, the pineapple is sometimes used as a symbol of Hawaii. Further, foods with pineapple in them are sometimes known as “Hawaiian” for this reason alone.

In the Philippines, “Smooth Cayenne” was introduced in the early 1900s by the US Bureau of Agriculture during the American colonial period. Dole and Del Monte established plantations in the island of Mindanao in the 1920s; in the provinces of Cotabato and Bukidnon, respectively. Large scale canning had started in Southeast Asia, including in the Philippines, from 1920. This trade was severely damaged by World War II, and Hawaii dominated the international trade until the 1960s.

The Philippines remain one of the top exporters of pineapples in the world.

      What does this do that a regular bus cannot do? What does this do that a tram cannot do? Sorry but this is getting classified as “weird bus” in my head, which is neat, but definitely not a train.

        The central government wanted a system for the fast growing cities which are small or medium sized. This system is a good way to build a system which can be afforded, built, used right away but the things which are built are not a waste when bigger system is needed. Station and right-of-way lane are easily converted into true tram system. Capacity is high like the tram and it is accessible like tram with boarding at level. For city which is growing it is also good that it is flexible. If route plan is not good (slow, no rider, other problem) it is not as expensive to change as tram. When the demand is ready and the route is good, it can easily become a tram or light rail and some of the cost is already paid. It can also detour and the software is aware of when it is needed. Useful for fast growing city.

          Thank you, this is a really in-depth answer! I have some more questions if you don’t mind.

          1. This project is pretty clearly a gadgetbahn which is why I am so skeptical. This doesn’t mean that the project is doomed or not useful, there have been many systems classified as gadgetbahns that have more than proved their worth, like VAL or monorails in some cases like the one in Chongqing. How do you make sure that this ends up being the next VAL and not the next Hyperloop or Transit Elevated Bus?

          2. Is this the ARRT system or a different semi-related system?

          3. Can the entire bus be extended to be very long and steered with computer help or are the only steerable wheels at the ends?

          4. Is there completely level boarding onto the bus without ramps so wheelchair users can get on and off effectively and quickly?

          5. How automated is the bus and how does it work?

            • The project was requested to solve a real problem. There was a lot of studying done to find the problem of fast growing cities which do not have a large transit system. I think the way to make it succed is to continue to listen to the operator feedback and adjust. CRRC is a state company so solving the problem is most important. It is helpful that the goal is to be replaced eventually and even then it can be used as a bus.

            • Is that. The one in use right now is the basic version which there has been a lot of development from. Development process is iterative because this has worked for trains for a long time.

            • It can! Three, four, five cars length currently. Steering is by hydraulic control on each unit. It can also connect to another vehicle in front and follow behind with no driver. Computer assisted steering is used. It is intended that it should be easy to train for articulated bus driver. The driver does not normally steer but must know how to do it.

            • It does.

            • The bus is half automated. The paint two paint line on the ground serve as “track” and it will stay inside. There is a driver inside but they do not do much in normal day. LiDAR and cameras detect the environment and warn the driver. I am working on increasing the automation of the system but CRRC and the government are very conservative about this.

              Thanks for answering the questions of a skeptic! I think I’m seeing a niche for this project, which is BRT that needs higher capacity that needs to be built very quickly. Long, long buses can do more than even bi-articulated buses and the completely level boarding will make getting on and off easier. I still think it’s a very small niche but I see some of the benefits of such a project. I’m imagining a 5-car version of this thing whooshing through a turn in a very narrow street in some hilly city, made possible by the semi-automation. This should allow any city to paint some lines on their streets and have a BRT-like thing whooshing in a matter of weeks. One more compliment I would like to make are the interiors, which are proper rapid transit interiors. The niche I see this filling is similar to the niche that BRT systems fill in South American cities but with a bit more capacity.

      Very cool, what part of the software are you working on specifically?

      I’m a shit coder but I generally understand high level concepts if you wanna use some jargon

        Sensor and control system for driver assistance, lane keeping (using lines on the road), automation. It is a real time system which uses the LiDAR and cameras to make deterministic quick backul decision about behavior, communicate with seperate module with more complicated image recognition.

      Looks pretty cool. Is there a driver or is it fully automated? How does it deal with dumb drivers entering its right of way? Why not have a catenary?

        Version in China uses a driver for now. This is safer in traffic. It could be fully automated but this is in development. My work is actually doing this as well as driver assistance. There are cameras and LiDAR sensors which can see things in the right of way to stop. The car will also get a traffic ticket automatically 😂.

        It would be very easy to put pantograph on it, could probably be requested by purchaser. The reason it does not have one is because the central government want it for the small and medium fast growing cities and so they request: low cost to install, easy to upgrade and reuse the station, do not limit which type of upgrade can be made. Charge at the station requires enough power at the station for any upgrade.
