Annona Squamosa
''Annona squamosa'' is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar-apples or . It tolerates a tropical lowland climate better than its relatives ''Annona reticulata'' and ''Annona cherimola'' (whose fruits often share the same name) helping make it the most widely cultivated of these species. ''Annona squamosa'' is a small, semi-(or late) deciduous, much-branched shrub or small tree tall similar to soursop ('' Annona muricata''). Description The fruit of ''A. squamosa'' (sugar-apple) has sweet whitish pulp, and is popular in tropical markets. Stems and leaves Branches with light brown bark and visible leaf scars; inner bark light yellow and slightly bitter; twigs become brown with light brown dots (lenticels – small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue). Thin, simple, alternate leaves occur singly, long and wide; rounded at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleoethnobotany
Paleoethnobotany (also spelled palaeoethnobotany), or archaeobotany, is the study of past human-plant interactions through the recovery and analysis of ancient plant remains. Both terms are synonymous, though paleoethnobotany (from the Greek words ''palaios'' αλαιόςmeaning ancient, ''ethnos'' θνοςmeaning race or ethnicity, and ''votano'' ότανοmeaning plants) is generally used in North America and acknowledges the contribution that ethnographic studies have made towards our current understanding of ancient plant exploitation practices, while the term archaeobotany (from the Greek words ''archaios'' ρχαίοςmeaning ancient and ''votano'') is preferred in Europe and emphasizes the discipline's role within archaeology. As a field of study, paleoethnobotany is a subfield of environmental archaeology. It involves the investigation of both ancient environments and human activities related to those environments, as well as an understanding of how the two co-evolv ...

Acetogenin
Acetogenins are a class of polyketide natural products found in plants of the family Annonaceae. They are characterized by linear 32- or 34-carbon chains containing oxygenated functional groups including hydroxyls, ketones, epoxides, tetrahydrofurans and tetrahydropyrans. They are often terminated with a lactone or butenolide. Over 400 members of this family of compounds have been isolated from 51 different species of plants. Many acetogenins are characterized by neurotoxicity. Examples include: * Annonacin * Annonins * Bullatacin * Uvaricin Structure Structurally, acetogenins are a series of C-35/C-37 compounds usually characterized by a long aliphatic chain bearing a terminal methyl-substituted α,β-unsaturated γ-lactone ring, as well as one to three tetrahydrofuran (THF) rings. These THF rings are located along the hydrocarbon chain, along with a number of oxygenated moieties (hydroxyls, acetoxyls, ketones, epoxides) and/or double bonds. Research Acetogenins have ...

Eating
Eating (also known as consuming) is the ingestion of food, typically to provide a heterotrophic organism with energy and to allow for growth. Animals and other heterotrophs must eat in order to survive — carnivores eat other animals, herbivores eat plants, omnivores consume a mixture of both plant and animal matter, and detritivores eat detritus. Fungi digest organic matter outside their bodies as opposed to animals that digest their food inside their bodies. For humans, eating is an activity of daily living. Some individuals may limit their amount of nutritional intake. This may be a result of a lifestyle choice, due to hunger or famine, as part of a diet or as religious fasting. Eating practices among humans Many homes have a large kitchen area devoted to preparation of meals and food, and may have a dining room, dining hall, or another designated area for eating. Most societies also have restaurants, food courts, and food vendors so that people may eat when away f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soursop
Soursop (also called ''graviola, guyabano'', and in Hispanic America, ''guanábana'') is the fruit of ''Annona muricata'', a broadleaf, flowering, evergreen tree. It is native to the tropical regions of the Americas and the Caribbean and is widely propagated. It is in the same genus, '' Annona'', as cherimoya and is in the Annonaceae family. The soursop is adapted to areas of high humidity and relatively warm winters; temperatures below will cause damage to leaves and small branches, and temperatures below can be fatal. The fruit becomes dry and is no longer good for concentrate. With an aroma similar to pineapple, the flavor of the fruit has been described as a combination of strawberries and apple with sour citrus flavor notes, contrasting with an underlying thick creamy texture reminiscent of banana. Soursop is widely promoted (sometimes as "graviola") as an alternative cancer treatment, but there is no reliable medical evidence it is effective for treating cancer or an ...

Sugar-apple
The sugar-apple or sweet-sop is the edible fruit of ''Annona squamosa'', the most widely grown species of '' Annona'' and a native of tropical climate in the Americas and West Indies. Spanish traders aboard the Manila galleons docking in the Philippines brought it to Asia. The fruit is spherical-conical, in diameter and long, and weighing , with a thick rind composed of knobby segments. The color is typically pale green through blue-green, with a deep pink blush in certain varieties, and typically has a bloom. It is unique among ''Annona'' fruits in being segmented; the segments tend to separate when ripe, exposing the interior. The flesh is fragrant and sweet, creamy white through light yellow, and resembles and tastes like custard. It is found adhering to seeds forming individual segments arranged in a single layer around a conical core. It is soft, slightly grainy, and slippery. The hard, shiny seeds may number 20–40 or more per fruit and have a brown to black coat, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
