Friedrich Markgraf
Friedrich Markgraf (1 February 1897 in Berlin-Friedenau – 8 March 1987 in Zurich) was a German botanist. Life and work After secondary school, Markgraf studied biology at the Friedrich Wilhelm University Berlin. In 1922 he was awarded a Ph.D. for a thesis on the subject of a botanic-ecological study of the Bredower forest near Berlin. After his habilitation he became first a professor of botany at the Friedrich Wilhelm University in Berlin and then at the Ludwig Maximilian University of Munich and director of the Botanical Garden Munich-Nymphenburg (1956-1958). Markgraf was also visiting professor of botany at the University of Zurich. During his teaching and research activities, he was primarily concerned with questions of botanical systematics, plant morphology and phytogeography and he also undertook research while travelling in the Mediterranean. In particular he made an important start on the study of the local flora of Albania. He acted as the Regional Adviser o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Botanischer Garten München-Nymphenburg
The Botanischer Garten München-Nymphenburg (21.20 hectares) is a botanical garden and arboretum located at Menzinger Str. 65, Munich, Bavaria, Germany. It is open daily, except on 24 and 31 December; an admission fee is charged. History Munich's first botanical garden, now called the "old botanical garden", was established in 1809 to designs by Friedrich Ludwig von Sckell near Karlsplatz, where its remains are still visible. The old botanical garden was replaced by a new garden created next to the park of Schloss Nymphenburg in 1912/13 and officially opened on 10 May 1914. The garden was designed by Peter Holfelder (1878–1936) who worked closely with Walter Kupper (1874–1953) and Leonhard Dillis (1871–1946). Description Today the garden cultivates about 19,600 species and subspecies on approximately 18 hectares. Its mission is to provide a beautiful and restful environment as well as educate the public about plants and nature more broadly. Major collections in ...

Alpine Garden
An alpine garden (or alpinarium, alpinum) is a domestic or botanical garden, or more often a part of a larger garden, specializing in the collection and cultivation of alpine plants growing naturally at high altitudes around the world, such as in the Caucasus, Pyrenees, Rocky Mountains, Alps, Himalayas and Andes. It is one of the most common types of rock garden. An alpine garden tries to imitate the conditions of the plants' place of origin. One example of this is using large stones and gravel beds, rather than the soil that naturally grows there. Though the plants can cope with low temperatures, they dislike standing in damp soil during the winter months. The soil used is typically poor (sandy) but extremely well-drained. One of the main obstacles in developing an alpine garden is the unsuitable conditions which exist in some areas, particularly mild or severe winters and heavy rainfall, such as those present in the United Kingdom and Ireland. This can be avoided by growing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Schacht
Wilhelm Schacht (born 11 December 1903 in Munich; died 17 February 2001 in Frasdorf) was a German botanist, gardener, photographer and author. He became known for being senior staff member of Botanischer Garten München-Nymphenburg, whose open air department he took care of for 21 years. The gardener Born in Munich as son of German art painter In 1927 Schacht became an inspector for park areas of Tsar Boris III of Bulgaria along the coast of the Black Sea. In 1936 Schacht became director of all royal nurseries of Bulgaria. With support of the monarch, who was interested in botany by himself, Schacht shaped and took care of the royal gardens. He worked in Bulgaria until 1944. Shortly before the end of the Second World War, Schacht returned to Germany and attended the gardens of former Tsar Ferdinand I of Bulgaria, father of Boris III, in Coburg.

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetraploid
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by meio ...

Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.
