Bonsai Cultivation And Care
Bonsai cultivation and care involves the long-term cultivation of small trees in containers, called ''bonsai'' in the Japanese tradition of this art form. Similar practices exist in other Japanese art forms and in other cultures, including ''saikei'' (Japanese), ''penjing'' (Chinese), and Hòn Non Bộ, ''hòn non bộ'' (Vietnamese). Trees are difficult to cultivate in containers, which restrict root growth, nutrition uptake, and resources for transpiration (primarily soil moisture). In addition to the root constraints of containers, bonsai trunks, branches, and foliage are extensively shaped and manipulated to meet Bonsai aesthetics, aesthetic goals. Specialized tools and techniques are used to protect the health and vigor of the subject tree. Over time, the artistic manipulation of small trees in containers has led to a number of cultivation and care approaches that successfully meet the practical and the artistic requirements of bonsai and similar traditions.

Trident Maple Bonsai 202, October 10, 2008
A trident (), () is a three-tine (structural), pronged spear. It is used for spear fishing and historically as a polearm. As compared to an ordinary spear, the three tines increase the chance that a fish will be struck and decrease the chance that a fish will be able to dislodge itself if struck badly. On the other hand, they are not so many as to overly reduce the spear's Pressure#Examples, concentration of force for piercing. The trident is the tool of Poseidon (Greek mythology, Greek) or Neptune (mythology), Neptune (Roman mythology, Roman) used for the protection of the sea realms, the god of the sea in classical mythology. Other sea deities such as Amphitrite or Triton (mythology), Triton were also often depicted with a trident in classical art. Later, tridents were used in medieval heraldry, sometimes held by a merman or Triton (mythology)#Tritons, triton. In Hindu mythology, Hinduism, it is the weapon of Shiva and is known as a ''trishula'' (Sanskrit for "triple-spear"). It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snag (ecology)
In forest ecology, a snag is a standing dead or dying tree, often missing a top or most of the smaller branches. In freshwater ecology the term ''snag'' refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris. Snags provide habitat for a wide variety of wildlife but pose hazards to river navigation. When used in manufacturing, especially in Scandinavia, they are often called dead wood and in Finland, kelo wood. Forest snags Snags are an important structural component in forest communities, making up 10–20% of all trees present in old-growth tropical, temperate, and boreal forests. Snags and downed coarse woody debris represent a large portion of the woody biomass in a healthy forest. In temperate forests, snags provide critical habitat for more than 100 species of bird and mammal, and snags are often called 'wildlife trees' by foresters. Dead, decaying wood supports a rich comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acer Buergerianum
''Acer buergerianum'' (trident maple; ) is a species of maple native to eastern China (from Shandong west to southeastern Gansu, south to Guangdong, and southwest to Sichuan), Taiwan and Japan. The specific epithet is a patronym honoring Dutch plant hunter J. Buerger (1804-1858). Description It is a small to medium-sized deciduous tree reaching a height of 5–20 m with a trunk up to 50 cm diameter. The leaves are in opposite pairs, 2.5–8 cm long (excluding the 2–5 cm petiole) and 3.5–6.5 cm broad, hard, glossy dark green above, paler below, usually with three lobes; on mature trees the lobes forward-pointing and with smooth margins, on young trees with more spreading lobes and serrated margins. The flowers are produced in spring, yellow-green, in pendulous corymbs; they are small, with five greenish sepals and five yellow-white petals about 2 mm long, and eight stamens. The fruit is a samara with two winged seeds, each seed 4–7 mm diameter, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.

Grafting
Grafting or graftage is a horticulture, horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion () while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together. The natural equivalent of this process is inosculation. The technique is most commonly used in asexual reproduction, asexual plant propagation, propagation of commercially grown plants for the horticultural and agricultural trades. The scion is typically joined to the rootstock at the soil line; however, top work grafting may occur far above this line, leaving an understock consisting of the lower part of the trunk and the root system. In most cases, the stock or rootstock is selected for its roots and the scion is selected for its Plant stem, stems, Leaf, leaves, flowers, or fruits. The scion contains the desired genes to be duplicated in future production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignin
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are polymers made by cross-linking phenolic precursors. History Lignin was first mentioned in 1813 by the Swiss botanist A. P. de Candolle, who described it as a fibrous, tasteless material, insoluble in water and alcohol but soluble in weak alkaline solutions, and which can be precipitated from solution using acid. He named the substance "lignine", which is derived from the Latin word '' lignum'', meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose and chitin. Lignin constitutes 30% of terrestrial non-fossil organic carbon on Earth, and 20 to 35% of the dry mass of wood. Lignin is present in red algae, which suggest that the common ancestor ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Bonsai IMG 6394
Bonsai (; , ) is the Japanese art of growing and shaping miniature trees in containers, with a long documented history of influences and native Japanese development over a thousand years, and with unique aesthetics, cultural history, and terminology derived from its evolution in Japan. Similar arts exist in other cultures, including Korea's ''bunjae'', the Chinese art of ''penjing'', and the miniature living landscapes of Vietnamese . The loanword ''bonsai'' has become an umbrella term in English, attached to many forms of diminutive potted plants, and also on occasion to other living and non-living things. According to Stephen Orr in ''The New York Times'', " the West, the word is used to describe virtually all miniature container trees, whether they are authentically trained bonsai or just small rooted cuttings. Technically, though, the term should be reserved for plants that are grown in shallow containers following the precise tenets of bonsai pruning and training, resulti ...

Ramification (botany)
In botany, ramification is the divergence of the stem and limbs of a plant into smaller ones, i.e., trunk into branches, branches into increasingly smaller branches, and so on. Gardeners stimulate the process of ramification through pruning, thereby making trees, shrubs, and other plants bushier and denser. Short internodes (the section of stem between nodes, i.e., areas where leaves are produced) help increase ramification in those plants that form branches at these nodes. Long internodes (which may be the result of over-watering, the over-use of fertilizer, or a seasonal "growth spurt") decrease a gardener's ability to induce ramification in a plant. A high degree of ramification is essential for the creation of topiary as it enables the topiary artist to carve a bush or hedge into a shape with an even surface. Ramification is also essential to practitioners of the art of bonsai as it helps re-create the form and habit of a full-size tree in a small tree grown in a containe ...
