African Blackwood
''Dalbergia melanoxylon'' (African blackwood, grenadilla, or mpingo) in French ''Granadille d'Afrique'' is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea, to southern regions of Tanzania to Mozambique and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments, sculptures vinyago in Swahili language and fine furnitures. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates. African blackwood is a small tree, reaching 4–15 m tall, with grey bark and spiny shoots. The leaves are deciduous in the dry season, alternate, 6–22 cm long, pinnately compound, with 6–9 alternately arranged leaflets. The flowers are white and produced in dense ...

Jean Baptiste Antoine Guillemin
Jean Baptiste Antoine Guillemin (20 January 1796 in Pouilly-sur-Saône – 15 January 1842 in Montpellier) was a French botanist. He studied at the municipal college in Seurre, where he was considered one of the most distinguished pupils. Upon leaving school he was placed with a lawyer. He worked there for eighteen months, but his interest in chemistry and desire to obtain a commission as a military pharmacist, at a time when it was difficult to avoid conscription, caused him to abandon the study of law. In 1812, he was apprenticed to a pharmacist in Dijon. After two years in that city, he went to Geneva, where he studied with Jean Pierre Étienne Vaucher (1763–1841) and Augustin Pyramus de Candolle (1778–1841). One day, while collecting plants in the Alps, he fell and broke his right arm. The injury was slow to heal, and the accident left him with permanent stiffness in the elbow joint. In 1820 he relocated to Paris, where he became curator of the herbarium and library ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Recorder (musical Instrument)
The recorder is a family of woodwind musical instruments in the group known as ''internal duct flutes'': flutes with a whistle mouthpiece, also known as fipple flutes, although this is an archaic term. A recorder can be distinguished from other duct flutes by the presence of a thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition. Recorders are made in various sizes with names and compasses roughly corresponding to various vocal ranges. The sizes most commonly in use today are the soprano (also known as descant, lowest note C5), alto (also known as treble, lowest note F4), tenor (lowest note C4), and bass (lowest note F3). Recorders were traditionally constructed from wood or ivory. Modern professional instruments are almost invariably of wood, often boxwood; student and scholastic recorders are commonly of moulded plastic. The recorders' internal and ext ...

Piccolo
The piccolo ( ; ) is a smaller version of the western concert flute and a member of the woodwind family of musical instruments. Sometimes referred to as a "baby flute" or piccolo flute, the modern piccolo has the same type of fingerings as the standard transverse flute, but the sound it produces is an octave higher. This has given rise to the name ottavino (), by which the instrument is called in Italian and thus also in scores of Italian composers. Piccolos are often orchestrated to double the violins or the flutes, adding sparkle and brilliance to the overall sound because of the aforementioned one-octave transposition upwards. The piccolo is a standard member in orchestras, marching bands, and wind ensembles. History Since the Middle Ages, evidence indicates the use of octave transverse flutes as military instruments, as their penetrating sound was audible above battles. In cultured music, however, the first piccolos were used in some of Jean Philippe Rameau's works i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flute
The flute is a member of a family of musical instruments in the woodwind group. Like all woodwinds, flutes are aerophones, producing sound with a vibrating column of air. Flutes produce sound when the player's air flows across an opening. In the Hornbostel–Sachs classification system, flutes are edge-blown aerophones. A musician who plays the flute is called a flautist or flutist. Paleolithic flutes with hand-bored holes are the earliest known identifiable musical instruments. A number of flutes dating to about 53,000 to 45,000 years ago have been found in the Swabian Jura region of present-day Germany, indicating a developed musical tradition from the earliest period of modern human presence in Europe.. Citation on p. 248. * While the oldest flutes currently known were found in Europe, Asia also has a long history with the instrument. A playable bone flute discovered in China is dated to about 9,000 years ago. The Americas also had an ancient flute culture, with instrumen ...

Oboe
The oboe ( ) is a type of double-reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic, resin, or hybrid composites. The most common type of oboe, the soprano oboe pitched in C, measures roughly long and has metal Key (instrument), keys, a conical Bore (wind instruments), bore and a flared bell. Sound is produced by blowing into the Reed (instrument), reed at a sufficient air pressure, causing it to vibrate with the air column. The distinctive tone is versatile and has been described as "bright". When the word ''oboe'' is used alone, it is generally taken to mean the soprano member rather than other instruments of the family, such as the bass oboe, the cor anglais (English horn), or oboe d'amore. Today, the oboe is commonly used as orchestral or solo instrument in Orchestra, symphony orchestras, concert bands and chamber music, chamber ensembles. The oboe is especially used in classical music, film music, some ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarinet
The clarinet is a Single-reed instrument, single-reed musical instrument in the woodwind family, with a nearly cylindrical bore (wind instruments), bore and a flared bell. Clarinets comprise a Family (musical instruments), family of instruments of differing sizes and pitches. The clarinet family is the largest woodwind family, ranging from the contrabass clarinet, BB♭ contrabass to the A-flat clarinet, A♭ piccolo. The B soprano clarinet is the most common type, and is the instrument usually indicated by the word "clarinet". German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime around 1700 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and airtight pads were added to improve the tone and playability. Today the clarinet is a standard fixture of the orchestra and concert band and is used in classical music, military bands, klezmer, jazz, and other styles. Etymol ...

Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legume
Legumes are plants in the pea family Fabaceae (or Leguminosae), or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure. Legumes produce a botanically unique type of fruit – a simple fruit, simple Dry fruits, dry fruit that develops from a simple carpel and usually Dehiscence (botany) , dehisces (opens along a seam) on two sides. Most legumes have Symbiosis , symbiotic nitrogen fixation , nitrogen-fixing bacteria, Rhizobia, in structures called root nodules. Some of the fixed nitrogen becomes available to later crops, so legumes play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and Pea , green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
