Gyrinops
''Gyrinops'' is a genus of nine species of tree In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are ...s, called lign aloes or lign-aloes trees, in the ''Thymelaeaceae'' family. They are native to Southeast Asia and the Indian Subcontinent. The genus ''Gyrinops'' is closely related to ''Aquilaria'' and in the past all species were considered to belong to ''Aquilaria.'' Agarwood production Together with ''Aquilaria'' the genus is best known as the principal producer of the resin-suffused agarwood.Barden, Angela (2000) ''Heart of the Matter: Agarwood Use and Trade and CITES Implementation for Aquilaria malaccensis'' TRAFFIC International, Cambridge, Ng, L.T., Chang Y.S. and Kadir, A.A.

Agarwood
Agarwood, aloeswood, eaglewood or gharuwood is a fragrant dark resinous wood used in incense, perfume, and small carvings. This resinous wood is most commonly referred to as "Oud" or "Oudh". It is formed in the heartwood of aquilaria trees when the Acquilara Tree becomes infected with a type of mold (''Phialophora parasitica'') and secretes a resin to combat the mold. Prior to infection, the heartwood is odourless, relatively light and pale coloured; however, as the infection progresses, the tree produces a dark aromatic resin, called aloes (not to be confused with ''Aloe ferox'', the succulent commonly known as the bitter aloe) or agar (not to be confused with the edible, algae-derived agar) as well as ''gaharu'', ''jinko'', ''oud'', or ''oodh'' ''aguru'' (not to be confused with bukhoor), in response to the attack, which results in a very dense, dark, resin-embedded heartwood. The resin-embedded wood is valued in East and South Asian cultures for its distinctive fragrance, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyrinops Walla
''Gyrinops walla'' is a species in the genus '' Gyrinops'' of the family Thymelaeaceae. It was described by Joseph Gaertner. The tree grows up to 15 m high. Its bark is thin and brownish-grey color. Leaves are 1–6 mm long and yellowish-white flower's pedicels are 3–4 mm long. ''Gyrinops walla'' is found in wet zone of Sri Lanka and very rarely in southwest India. It uses as agarwood and agarwood resin In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on n .... The tree has commercial value that resulted to smuggling. In Sri Lanka, it is known as "Walla patta". Due to the demand of the tree, Sadaharitha Plantations Limited released a study on growing Gyrinops walla in home gardens. Some organizations conducted the research with the support of the Sri Lankan government. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, '' De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
