Pod Corn
Pod corn or wild maize is a variety of maize. It is not a wild ancestor of maize but rather a mutant that forms leaves around each kernel. Pod corn (''tunicata'' Sturt) is not grown commercially, but it is preserved in some localities. Pod corn forms glumes around each kernel which is caused by a mutation at the Tunicate locus. Because of its bizarre appearance, pod corn has had a religious significance to certain Native American tribes. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn Sweet corn (''Zea mays'' convar. ''saccharata'' var. ''rugosa''), also called sugar corn and pole corn, is a variety of maize grown for human consumption with a high sugar content. Sweet corn is the result of a naturally occurring recessive muta ....Linda Campbell Franklin, "Corn," in Andrew F. Smith (ed.), ''The Oxford Encyclopedia of Food and Drink in America''. 2nd ed.

Zea Mays
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and corn ...

EOLSS
The Encyclopedia of Life Support Systems (EOLSS) is an integrated compendium of twenty one encyclopedias. The first Earth Summit of 1992, held in Rio de Janeiro, issued a document that is now famous as Agenda 21. This document refers to the Earth's life support systems, considering the whole of our planet as a grand intensive care unit that supports all forms of life (both natural and human-engineered systems). The Encyclopedia of Life Support Systems (EOLSS) is based on this concept and the above definition of 'life support systems'. It is intended to be a source of knowledge conveniently accessible at a single location, knowledge that could be useful in providing an understanding of global systems and issues with the potential to render decisions well informed to ensure the ability of our planet to support life. Unlike most encyclopedias, the contents of which are alphabetically arranged, EOLSS has a thematic organization (Theme Level, Topic Level and Article Level where Theme ...

Glume
In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and palea. In grasses, two bracts known as "glumes" form the lowermost organs of a spikelet (there are usually two but one is sometimes reduced; or rarely, both are absent). Glumes may be similar in form to the lemmas, the bracts at the base of each floret This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary o ....

Tunica (biology)
In biology, a tunica (, ; ) is a layer, coat, sheath, or similar covering. The word came to English from the New Latin of science and medicine. Its literal sense is about the same as that of the word ''tunic'', with which it is cognate. In biology one of its senses used to be the taxonomic name of a genus of plants, but the nomenclature has been revised and those plants are now included in the genus ''Petrorhagia''. In modern biology in general, ''tunica'' occurs as a technical or anatomical term mainly in botany and zoology. It usually refers to membranous structures that line or cover particular organs. In many such contexts ''tunica'' is used interchangeably with ''tunic'' according to preference. An organ or organism that has a tunic(a) may be said to be ''tunicate'', as in a ''tunicate bulb''. This adjective ''tunicate'' is not to be confused with the noun ''tunicate'', which refers to a member of the subphylum '' Tunicata''. Botanical and related usages In botany there are s ...

Dent Corn
Dent corn, also known as grain corn, is a type of field corn with a high soft starch content. It received its name because of the small indentation, or "dent", at the crown of each kernel on a ripe ear of corn. Reid's Yellow Dent is a variety developed by central Illinois farmer James L. Reid. Reid and his father, Robert Reid, moved from Brown County, Ohio to Tazewell County, Illinois in 1846 bringing with them a red corn variety known as "Johnny Hopkins", and crossed it with varieties of flint corn and flour corn. Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair. Most of the corn grown in the United States today is yellow dent corn or a closely related variety derived from it. Dent corn is the variety used in food manufacturing as the base ingredient for cornmeal flour (used in the baking of cornbread), corn chips, tortillas, and taco shells. Starch derived from this high-starch content variety is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint Corn
Flint corn ('' Zea mays'' var. ''indurata''; also known as Indian corn or sometimes calico corn) is a variant of maize, the same species as common corn. Because each kernel has a hard outer layer to protect the soft endosperm, it is likened to being hard as flint; hence the name. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn. History With less soft starch than dent corn ('' Zea mays indentata''), flint corn does not have the dents in each kernel from which dent corn gets its name. This is one of the three types of corn cultivated by Native Americans, both in New England and across the northern tier, including tribes such as the Pawnee on the Great Plains. Archaeologists have found evidence of such corn cultivation in what is now the United States before 1000 BC. Corn was originally domesticated in Mexico by native peoples about 9,000 years ago. They used many generations of selective breeding to transform a wild teosin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popcorn
Popcorn (also called popped corn, popcorns or pop-corn) is a variety of corn kernel which expands and puffs up when heated; the same names also refer to the foodstuff produced by the expansion. A popcorn kernel's strong hull contains the seed's hard, starchy shell endosperm with 14–20% moisture, which turns to steam as the kernel is heated. Pressure from the steam continues to build until the hull ruptures, allowing the kernel to forcefully expand, to 20 to 50 times its original size, and then cool. Some strains of corn ( taxonomized as ''Zea mays'') are cultivated specifically as popping corns. The ''Zea mays'' variety ''everta'', a special kind of flint corn, is the most common of these. Popcorn is one of six major types of corn, which includes dent corn, flint corn, pod corn, flour corn, and sweet corn. History Corn was domesticated about 10,000 years ago, in what is now Mexico. Archaeologists discovered that people have known about popcorn for thousands of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flour Corn
Flour corn (''Zea mays'' var. ''amylacea'') is a variety of corn with a soft starchy endosperm and a thin pericarp. It is primarily used to make corn flour. This type, frequently found in Aztec and Inca graves, is widely grown in the drier parts of the United States, western South America and South Africa. The large-seeded corns of Peru are used in the preparation of ''chicha''. In South Africa they are known as ''bread mealies''. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn Sweet corn (''Zea mays'' convar. ''saccharata'' var.

Sweet Corn
Sweet corn (''Zea mays'' convar. ''saccharata'' var. ''rugosa''), also called sugar corn and pole corn, is a variety of maize grown for human consumption with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Sweet corn is picked when still in the immature (milk stage) and prepared and eaten as a vegetable, rather than field corn, which is harvested when the kernels are dry and mature (dent stage). Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy. It is one of the six major types of maize, the others being dent corn, flint corn, pod corn, popcorn, and flour corn. According to the USDA, 100 grams of raw yellow sweet corn contains 3.43 g glucose, 1.94 g fructose, and 0.89 g sucrose. Hist ...
