Giant Pumpkin
A giant pumpkin is an orange fruit of the squash '' Cucurbita maxima'', commonly weighing from to over .Karl, J. R. 2014. ''Cleaning the Giant Pumpkin'' History Growing giant pumpkins emerged out of the North American agricultural tradition. The Smithsonian notes that "improbably", giant pumpkins trace themselves to Henry David Thoreau, who in 1857 grew a pumpkin weighing , which he detailed in his unfinished work '' Wild Fruits''. The first competition giant pumpkins were grown by William Warnock of Ontario, Canada. His first record was , measured at the 1893 Chicago World's Fair. In 1900, Warnock's pumpkin was exhibited at the Paris World's Fair, and won a bronze medal. He beat his own record four years later, and began to provide advice to other growers on how to achieve large pumpkin yields. Warnock's record stood for some 70 years before a pumpkin growing renaissance emerged, and records were quickly shattered. Growing giant pumpkins remains a mostly North American ...

Cucurbita Maxima 'Atlantic Giant'1
''Cucurbita'' (Latin for gourd) is a genus of Herbaceous plant, herbaceous fruits in the gourd family (biology), family, Cucurbitaceae (also known as ''cucurbits'' or ''cucurbi''), native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, Variety (botany), variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus ''Lagenaria'', which is in the same family and subfamily as ''Cucurbita'', but in a different Tribe (biology), tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the ''Cucurbita'' species. Most ''Cucurbita'' species are herbaceous vines that grow several meters in length and have tendrils, but non-vining "bush" cultivars of ''C. pepo'' and ''C. maxima'' have also been developed. The yellow or orange flowers on a ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Ground Sloth
''Megatherium'' ( ; from Greek () 'great' + () 'beast') is an extinct genus of ground sloths endemic to South America that lived from the Early Pliocene through the end of the Pleistocene. It is best known for the elephant-sized type species ''M. americanum'', sometimes called the giant ground sloth, or the megathere, native to the Pampas through southern Bolivia during the Pleistocene. Various other smaller species belonging to the subgenus ''Pseudomegatherium'' are known from the Andes. ''Megatherium'' is part of the sloth family Megatheriidae, which also includes the similarly giant ''Eremotherium'', comparable in size to ''M. americanum,'' which was native to tropical South America, Central America and North America as far north as the southern United States. Only a few other land mammals equaled or exceeded ''M. americanum'' in size, such as large proboscideans (e.g., elephants) and the giant rhinoceros ''Paraceratherium''. ''Megatherium'' was first discovered in 1788 on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phloem
Phloem (, ) is the living biological tissue, tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as ''photosynthates'', in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark (botany), bark, hence the name, derived from the Ancient Greek word (''phloiós''), meaning "bark". The term was introduced by Carl Nägeli in 1858. Structure Phloem tissue consists of conducting Cell (biology), cells, generally called sieve elements, Ground tissue#Parenchyma, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Conducting cells (sieve elements) Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a Cell nucleus, nucleus and have very few organelles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Hu
David L. Hu (born circa 1979) is an American mathematician, roboticist, and biologist who is currently an associate professor at the engineering department of Georgia Tech. His research centers on animal behavior and movement, and is noted for its eccentricity. Hu was born in Rockville, Maryland. His father was a chemist who enjoyed collecting and dissecting road kill, which inspired his son's curiosity regarding the science of living things. Hu is married to Dr. Jia Fan, a data scientist employed by AT&T with whom he has two children. Hu's children have inspired some of his research projects. "From a diaper change with my son, I was inspired to study urination. From watching my daughter being born, I was inspired by her long eyelashes." Hu is known for focusing on irreverent and whimsical research subjects. In 2016 his work was criticized by Arizona Senator Jeff Flake as one of the twenty most wasteful federally funded research projects. Hu responded to this criticism with a TED ...

Azospirillum
''Azospirillum'' is a Gram-negative, microaerophilic, non- fermentative and nitrogen-fixing bacterial genus from the family of Rhodospirillaceae. ''Azospirillum'' bacteria can promote plant growth. Characteristics The genus ''Azospirillum'' belongs in the alpha-Proteobacteria class of bacteria. ''Azospirillum'' are gram-negative, do not form spores, and have a slightly-twisted oblong-rod shape. ''Azospirillum'' have at least one flagellum and sometimes multiple flagella, which they use to move rapidly. ''Azospirillum'' are aerobic, but many can also function as microaerobic diazotrophs, meaning, under low oxygen conditions, they can change inert nitrogen from the air into biologically useable forms. At least three species, ''A. melinis'', ''A. thiophilum'', and ''A. humicireducens'' are facultative anaerobes, and can live, if necessary, without oxygen. Growth of ''Azospirillum'' is possible between 5 °C and 42 °C and in substrates with a pH of 5 to 9, with optimal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycorrhiza
A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phosp ...

Cloche (agriculture)
In agriculture and gardening, a cloche (from French, ''cloche'' for "bell") is a covering for protecting plants from cold temperatures. The original form of a cloche is a bell-shaped glass cover that is placed over an individual plant; modern cloches are usually made from plastic. The use of cloches is traced back to market gardens in 19th century France, where entire fields of plants would be protected with cloches. In commercial growing, cloches have largely been replaced by row cover, and nowadays are mainly found in smaller gardens. History Parisian market gardens in the 1800s used 18-inch diameter bell-shaped glass jars (cloches) to protect plants in cold weather. They were used to protect everything from young seedlings to mature plants. Notched wooden sticks were used to prop up and vent the jars on sunny days, and were placed back down on the soil before nightfall. "Chase barn cloches", introduced in the early twentieth century by Major L.H. Chase, are constructed wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannula
A cannula (; Latin meaning 'little reed'; plural or ) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 24 gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula (extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Many types of cannulas exist: Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula is a piece of plastic tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intravenous Therapy
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilth
Tilth is a physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, soil biota, rate of water infiltration and drainage. Tilth can change rapidly, depending on environmental factors such as changes in moisture, tillage and soil amendments. The objective of tillage (mechanical manipulation of the soil) is to improve tilth, thereby increasing crop production; in the long term, however, conventional tillage, especially plowing, often has the opposite effect, causing the soil carbon sponge to oxidize, break down and become compacted. Soil with good tilth is spongy with large pore spaces for air infiltration and water movement. Roots only grow where the soil tilth allows for adequate levels of soil oxygen. Such soil also holds a reasonable supply of water and nutrients. Tillage, organic matter amendments, fert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedigree Chart
A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next, most commonly humans, show dogs, and race horses. Definition The word pedigree is a corruption of the Anglo-Norman French ''pé de grue'' or "crane's foot", either because the typical lines and split lines (each split leading to different offspring of the one parent line) resemble the thin leg and foot of a crane or because such a mark was used to denote succession in pedigree charts. A pedigree results in the presentation of family information in the form of an easily readable chart. It can be simply called as a "family tree". Pedigrees use a standardized set of symbols, squares represent males and circles represent females. Pedigree construction is a family history, and details about an earlier generation may be uncertain as memories fade. If the sex of the person is unknown a diamond is used. Someone with the ph ...
