Queen Sirikit Botanic Garden
Queen Sirikit Botanic Garden (QSBG) is a botanical garden in Mae Rim District, Chiang Mai Province, Thailand. It was opened in 1993 and is maintained under the auspices of the Botanical Garden Organization (BGO) of the Ministry of Natural Resources and Environment. Originally called the ''Mae Sa Botanic Garden'', it was renamed for Sirikit, Queen of Thailand, in 1994. The site is home to twelve greenhouses, placing the establishment among Thailand's largest glasshouse complexes. QSBG spreads over a vast area, from a hilly region near to the river Mae Sai (at an elevation of approx. ) to the site's highest point, at . Evergreen and dipterocarp trees occupy lower elevations, while pine forest is found in higher areas. QSBG displays plants and flowers year round. It was Thailand’s first botanical garden built according to international standards. It focuses on strengthening ''ex situ'' conservation of valuable Thai flora. The breeding programs for native Thai orchids are some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiang Mai
Chiang Mai (, from th, เชียงใหม่ , nod, , เจียงใหม่ ), sometimes written as Chiengmai or Chiangmai, is the largest city in northern Thailand, the capital of Chiang Mai province and the second largest city in Thailand. It is north of Bangkok in a mountainous region called the Thai highlands and has a population of 1.19 million people as of 2022, which is more than 66 percent of the total population of Chiang Mai province (1.8 million). Chiang Mai (meaning "New City" in Thai) was founded in 1296 as the new capital of Lan Na, succeeding the former capital, Chiang Rai. The city's location on the Ping River (a major tributary of the Chao Phraya River) and its proximity to major trading routes contributed to its historic importance. The city (''thesaban nakhon'', Thesaban#City-municipality, "city municipality") of Chiang Mai officially only covers most parts (40,2 km²) of the Mueang Chiang Mai district in the city centre and has a pop ...

Richard Eric Holttum
Richard Eric Holttum (20 July 189518 September 1990) was an English botanist and writer. Early life Holttum was born 20 July 1895 in Cambridgeshire, England, to English store owners of Quaker faith. He was educated at Bootham School, York. He studied at the University of Cambridge. He served with the Friends' Ambulance Unit on the Western Front during World War I, for which he was awarded the Croix de guerre. Career Having received botanical training, Holttum was given the role of assistant director at the Singapore Botanical Gardens in 1922, with the guidance of Isaac Henry Burkill. In Singapore, he performed some exhaustive studies, and was promoted to director in 1925, following the retirement of Burkill. His areas of expertise were the growth and cultivation of orchids. He continued working at the Singapore Botanical Gardens even during the Japanese occupation of the country. Holttum and Corner (assistant director at the Singapore Botanical Garden) were once detained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Musa (genus)
''Musa'' is one of two or three genera in the family Musaceae. The genus includes flowering plants producing edible bananas and plantains. Around 70 species of ''Musa'' are known, with a broad variety of uses. Though they grow as high as trees, banana and plantain plants are not woody and their apparent " stem" is made up of the bases of the huge leaf stalks. Thus, they are technically gigantic herbaceous plants. ''Musa'' species are used as food plants by the larvae of some Lepidoptera species, including the giant leopard moth and other ''Hypercompe'' species, including '' H. albescens'' (only recorded on ''Musa''), '' H. eridanus'', and '' H. icasia''. Description Banana plants represent some of the largest herbaceous plants existing in the present, with some reaching up to in height (59 feet (18 meters) in the case of '' Musa ingens''). The large herb is composed of a modified underground stem (rhizome), a false trunk of tightly rolled petioles, a netw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peninsular Malaysia
Peninsular Malaysia ( ms, Semenanjung Malaysia; Jawi: سمننجڠ مليسيا), or the States of Malaya ( ms, Negeri-negeri Tanah Melayu; Jawi: نڬري-نڬري تانه ملايو), also known as West Malaysia or the Malaysian Peninsula, is the part of Malaysia that occupies the southern half of the Malay Peninsula in Southeast Asia and the nearby islands. Its area totals , which is nearly 40% of the total area of the country; the other 60% is in East Malaysia. For comparison, it is slightly larger than England (130,395 km2). It shares a land border with Thailand to the north and a maritime border with Singapore to the south. Across the Strait of Malacca to the west lies the island of Sumatra, and across the South China Sea to the east lie the Natuna Islands of Indonesia. At its southern tip, across the Strait of Johor, lies the island country of Singapore. Peninsular Malaysia accounts for the majority (roughly 81.3%) of Malaysia's population and economy; as of 2017, it ... [...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.

Chromosome
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 si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of Peninsular Malaysia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
