Mauritia Flexuosa
''Mauritia flexuosa'', known as the moriche palm, ''ité'' palm, ''ita'', ''buriti'', ''muriti'', ''miriti'' (Brazil), ''canangucho'' (Colombia), ''morete or acho'' (Ecuador), ''palma real'' (Bolivia), or ''aguaje'' (Peru), is a Arecaceae, palm tree. It grows in and near swamps and other wet areas in tropical South America. ''Mauritia flexuosa'' can reach up to in height. Henderson and McBride both give a height of 165 feet (fifty meters). The trunk can be up to diameter at breast height The large leaves form a rounded crown. The tree produces Pneumatophores which can develop as much as from the trunk. suggesting a very extensive root system. The flowers are yellowish and appear from December to April. The fruit, which grows from December to June, is a chestnut color and is covered with shiny scales. The yellow flesh covers a hard, oval nut. The seeds float, and this is the means by which the palm tree propagates. In natural populations, the tree reaches very high densities. D ...

Carolus Linnaeus The Younger
Carl Linnaeus the Younger, Carolus Linnaeus the Younger, Carl von Linné den yngre (Swedish language, Swedish; abbreviated Carl von Linné d. y.), or ''Linnaeus filius'' (Latin for ''Linnaeus the son''; abbreviated L.fil. (outdated) or L.f. (modern) as a botanical authority; 20 January 1741 – 1 November 1783) was a Swedish natural history, naturalist. His names distinguish him from his father, the pioneering taxonomist Carl Linnaeus (1707–1778). Biography Carl Linnaeus the Younger was enrolled at the University of Uppsala at the age of 9 and was taught science by his father's List of students of Linnaeus, students, including Pehr Löfling, Daniel Solander, and Johan Peter Falk. In 1763, aged just 22, he succeeded his father as the head of Practical Medicine at Uppsala. His promotion to professor — without taking exams or defending a thesis — caused resentment among his colleagues. His work was modest in comparison to that of his father. His best-known work is the ''Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germinate
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an flowering plant, angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of Fungus, fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or conifer cone, cone after the union of male and female gamete, reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Dormant seeds are viable seeds that do not germinate because they require specific internal or environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-bellied Macaw
The red-bellied macaw (''Orthopsittaca manilatus''), also known as ''Guacamaya manilata'', is a medium-sized, mostly green parrot, a member of a group of large Neotropical parrots known as macaws. It is the largest of what are commonly called " mini-macaws". The belly has a large maroon patch which gives the species its name. It is endemic to tropical Amazonian South America (as well as the Caribbean island of Trinidad), from Colombia south to Amazonian Peru and Bolivia, and central Brazil as far as the northwestern cerrado. Its habitat is moriche (or buriti) palm (''Mauritia flexuosa'') swamp forests and sandy savannahs with palm groves. They are critically dependent on the Moriche palm for roosting, feeding and nesting. Although the bird is locally common, in places it has been adversely affected by clearing of the palms for use as posts, or to allow cattle ranching; also by capture for the pet trade. Not to be confused with the African red-bellied parrot (''Poicephalus rufi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carotenoids
Carotenoids () are yellow, orange, and red organic compound, organic pigments that are produced by plants and algae, as well as several bacteria, archaea, and Fungus, fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, maize, corn, tomatoes, Domestic Canary, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons and contain no oxygen). All are derivative (chemistry), derivatives of tetraterpenes, meaning that they are produced from 8 isoprene units and contain 40 carbon atoms. In general, carotenoids absorb wavelengths ranging from 400 to 550 nanometers (violet to green light). This causes the compounds to be deeply colored yellow, orange, or red. Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species, but many plant colors, especially reds and purpl ...

Tocopherols
Tocopherols (; TCP) are a class of organic compounds comprising various Methyl group, methylated phenols, many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was named ''tocopherol'', from Greek wiktionary:τόκος, τόκος ''tókos'' 'birth' and wiktionary:φέρειν, φέρειν ''phérein'' 'to bear or carry', that is 'to carry a pregnancy', with the ending ''-ol'' signifying its status as a chemical Alcohol (chemistry), alcohol. Α-tocopherol, α-Tocopherol is the main source found in supplements and in the European diet, where the main dietary sources are olive and sunflower oils, while G-tocopherol, γ-tocopherol is the most common form in the American diet due to a higher intake of soybean and corn oil. Forms Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to re ...

Oleic Acid
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 ''cis''-9, and a main product of Δ9-desaturase. It has the formula . The name derives from the Latin word '' oleum'', which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. It is a common component of oils, and thus occurs in many types of food, as well as in soap. Occurrence Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (trigl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhynchophorus Palmarum
The South American palm weevil, ''Rhynchophorus palmarum'', is a species of snout beetle. The adults are relatively large black beetles of approximately one and a half inch in length, and the larvae may grow to two inches in length. Biology and behavior These insects are attracted to the release of volatile compounds produced by injured palm trees. The larvae burrow through the hearts of palms, and their feeding can potentially kill an infested palm or serve as an avenue for secondary infections of bacterial disease. It is considered an important pest of cultivated coconut, date and oil palms, attacking thirty-five different species in twelve different families.Griffith, R. 1987"Red ring disease of coconut palm" ''Plant Disease'' 71: 193–196.Sanchez, P and H.

Palm Wine
Palm wine, known by several #Names, local names, is an alcoholic beverage created from the sap of various species of palm trees such as the Borassus, palmyra, date palms, and coconut palms. It is known by various names in different regions and is common in various parts of Africa, the Caribbean, South America, South Asia, Southeast Asia, and Micronesia. The word "toddy" traces back to the Proto-Dravidian language, Proto-Dravidian root "''tāẓ-'' (DED number: 3180)," which means palmyra/toddy palm and gave rise to forms like "tāḍi" or "tāṭi" in Telugu language, Telugu, Gondi language, Gondi, and Kolami, Kolami-Gadba; "tāri" or "tāḷi" in Kannada and Tulu language, Tulu. The Sanskrit word "tāḍi," which refers to an extract from palm trees, is a loanword from Dravidian. Palm wine production by smallholders and individual farmers may promote conservation as palm trees become a source of regular household income that may economically be worth more than the value of tim ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1,000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton ( United States customary units) and the long ton ( British imperial units). It is equivalent to approximately 2,204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (Mg), a less common way to express the same amount. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
