Edmond Albius
Edmond Albius (1829 – 9 August 1880) was a horticulturalist from Réunion. Born into slavery, Albius became an important figure in the cultivation of vanilla. At the age of 12, he invented a technique for pollinating vanilla orchids quickly and profitably. Albius's technique revolutionized the cultivation of vanilla and made it possible to profitably grow vanilla beans away from their native Mexico. Early life Albius was born in St. Suzanne, Réunion. His mother, a slave, died during his birth. The colonist keeping Edmond in slavery was Féréol Bellier Beaumont. Vanilla pollination French colonists brought vanilla beans to Réunion and nearby Mauritius in the 1820s with the hope of starting production there. However, the vines were sterile because no insect would pollinate them.

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horticulturists From Réunion
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes. In order to conserve the science of horticultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slaves From Réunion
Slavery and enslavement are both the state and the condition of being a slave—someone forbidden to quit one's service for an enslaver, and who is treated by the enslaver as property. Slavery typically involves slaves being made to perform some form of work while also having their location or residence dictated by the enslaver. Many historical cases of enslavement occurred as a result of breaking the law, becoming indebted, or suffering a military defeat; other forms of slavery were instituted along demographic lines such as race. Slaves may be kept in bondage for life or for a fixed period of time, after which they would be granted freedom. Although slavery is usually involuntary and involves coercion, there are also cases where people voluntarily enter into slavery to pay a debt or earn money due to poverty. In the course of human history, slavery was a typical feature of civilization, and was legal in most societies, but it is now outlawed in most countries of the w ...

People Of African Descent From Réunion
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Vanilla
Vanilla is a spice derived from orchids of the genus ''Vanilla (genus), Vanilla'', primarily obtained from pods of the Mexican species, flat-leaved vanilla (''Vanilla planifolia, V. planifolia''). Pollination is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old enslaved child who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollination, hand-pollinated. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier. By the end of the 20th century, Albius was considered the true discoverer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint-Denis, Réunion
Saint-Denis (, , unofficially Saint-Denis de La Réunion for disambiguation; ) is the prefecture (administrative capital) of the French overseas department and region of Réunion, in the Indian Ocean. It is located at the island's northernmost point, close to the mouth of the Rivière Saint-Denis. Saint-Denis is the most populous commune in the French overseas departments and the nineteenth most populous in all of France. At the 2019 census, there were 314,880 inhabitants in the metropolitan area of Saint-Denis (as defined by INSEE), 153,810 of whom lived in the city (commune) of Saint-Denis proper and the remainder in the neighbouring communes of La Possession, Sainte-Marie, Sainte-Suzanne, Saint-André, and Bras-Panon. History Foundation Saint-Denis was founded in 1669 by Étienne Regnault, first governor of Bourbon Island (as La Réunion was then called), on the northern side of the island, where a larger and more fertile plain was deemed more propitious for the deve ...

Plantation
A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on. The crops that are grown include cotton, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use the term is usually taken to refer only to large-scale estates, but in earlier periods, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northwards. It was used in most British colonies, but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantations, a ...

Jean Michel Claude Richard
Jean Michel Claude Richard (16 August 1787 – 1868) was a noted French botanist and plant collector active in Senegal, Madagascar, Mauritius, and Réunion, and a Chevalier of the Légion d'honneur. Richard was born in Volon, Haute-Saône. He was sent to Senegal in 1816 as the colony's gardener-in-chief, but served without obvious distinction until the arrival in 1822 of Baron Jacques-François Roger (1787–1849) who entrusted to Richard the creation of an experimental garden on the left bank of the Sénégal River, near the village of Nghiao, and named it ''Richard Toll'' (toll means "garden" in the Wolof language). Richard was responsible for all plants, buildings, and facilities, and under his direction a number of new species were introduced to Senegal, including bananas, manioc, oranges, sugar cane, and coffee. In February 1824 Richard was sent to Cayenne. Directed on 30 July 1824 to keep a diary of his experiences, he developed a catalog of the garden's species, and left S ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...
