Hans M. Heybroek
Hans M. Heybroek (born 1927, Bussum, died 2022, Wassenaar) (in Dutch) was a Dutch botanist best known for his research into the genus ''Ulmus'' at the Dorschkamp Research Institute for Forestry & Landscape Planning. Until his retirement in 1992, he was responsible for the raising and release of numerous elm hybrid cultivars, notably Columella (elm cultivar), 'Columella'. Specializing in phytopathology, Heybroek also investigated the Coral Spot fungus ''Nectria cinnabarina'' in elm. In 1960 he travelled to the Kashmir to search for a frost-hardy form of the Himalayan Elm ''Ulmus wallichiana'' as a source of anti-fungal genes for use in the Dutch elm research programme.

Bussum
Bussum () is a commuter town and former municipality in the Gooi region in the south east of the province of North Holland in the Netherlands near Hilversum. Since 2016, Bussum has been part of the new municipality of Gooise Meren. Bussum had a population of 33,595 in 2019 and covered an area of . History For a long time Bussum was not more than a hamlet situated amongst the heathlands of the Gooi and was first mentioned in 1306. In this time, Bussum was a large heathland with many small farms, sheep pens and forests as is shown on old maps. Since Bussum is situated near the fortified town Naarden it was governed by Naarden from 1369 onward. In 1470 Bussum was inhabited by about 250 people, which made it the smallest village in the Gooi. Bussum became independent from Naarden in 1817, yet it was not until the arrival of a railway line in 1874 that Bussum began to flourish. Two train stations were built in the town, that still exist today: Naarden-Bussum and Bussum Zuid (Dutch l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronald Melville (botanist)
Ronald Melville (12 March 1903 – 6 August 1985) He was an English botanist, based at the Royal Botanic Gardens Kew. He is chiefly remembered for his wartime research into rosehips as a source of vitamin C, prompted by the epidemic of scurvy amongst children owing to the reduced importation of fresh fruit. His research concluded that hips from the common Dog Rose ''Rosa canina'' held the highest concentration of the vitamin. In later years, he challenged the two-species taxonomy of the British elms proposed by Richens,Richens, R. H. (1984) ''Elm'', Cambridge University Press. identifying five distinct species, several varieties and numerous complex hybrids.Melville, R. (1978). On the discrimination of species in hybrid swarms with special reference to ''Ulmus'' and the nomenclature of ''U. minor'' (Mill.) and ''U. carpinifolia'' (Gled.). ''Taxon'' 27: 345-351, 1978.

People From Bussum
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ulmus Wallichiana
''Ulmus wallichiana'' Planch., the Himalayan elm, also known as the Kashmir elm and Bhutan elm, is a mountain tree ranging from central Nuristan in Afghanistan, through northern Pakistan and northern India to western Nepal at elevations of 800–3000 m. Although dissimilar in appearance, its common name is occasionally used in error for the cherry bark elm ''Ulmus villosa'', which is also endemic to the Kashmir, but inhabits the valleys, not the mountain slopes. The species is closely related to the wych elm ''U. glabra''. Description The Himalayan elm grows to 30 m tall, with a broad crown featuring several ascending branches. The bark of the trunk is greyish brown and longitudinally furrowed. The leaves are elliptic-acuminate, < 13 cm long by 6 cm broad on petioles 5–10 mm long. The samarae are usually orbicular, < 13 mm in diameter, on 5mm pedic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wassenaar long remained an unremarkable little town, known only as the home of the House of Wassenaer. It only began to gain notoriety in the 19th century when Louis Bonaparte ordered the co ...

Kashmir () is the northernmost geographical region of the Indian subcontinent.

Nectria Cinnabarina
''Nectria cinnabarina'', also known as coral spot, is a plant pathogen that causes cankers on broadleaf trees. This disease is polycyclic and infects trees in the cool temperate regions of the Northern Hemisphere. ''N. cinnabarina'' is typically saprophytic, but will act as a weak parasite if presented with an opportunity via wounds in the tree or other stressors that weaken the tree’s defense to the disease. A study published in 2011 showed that this complex consists of at least 4 distinct species. There are only a few ways to manage this disease with techniques such as sanitation and pruning away branches that have the cankers. ''N. cinnabarina'' is not as significant a problem as other ''Nectria'' spp., some of which are the most important pathogens to infect hardwood trees. Hosts and symptoms ''Nectria cinnabarina'', also known as coral spot, is a weak pathogen of broadleaf trees. While beech is the main host, the parasite can also affect Sycamore, Horse Chestnut, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
