Actinidia Valvata
''Actinidia valvata'' is a species of flowering plant in the Chinese gooseberry family Actinidiaceae, native to southern China. A deciduous climbing shrub, it is found in open woodlands and in thickets, preferring mountain valley bottoms, around above sea level. As a crop wild relative of kiwifruit, it is being studied for its resistance to waterlogging, with an eye towards using it as a rootstock.

Stephen Troyte Dunn
Stephen Troyte Dunn (26 August 1868, Bristol - 18 April, 1938, Sheen, Surrey, England) was a British botanist. He described and systematized a significant number of plants around the world, his input most noticeable in the Taxonomy (biology), taxonomy of the flora of China. Among the plants he first scientifically described was ''Bauhinia blakeana'', now the national flower of Hong Kong. Biography Born in Bristol in the family of Rev. James Dunn, of Northern Irish descent, S. T. Dunn was educated at Radley College, Radley, and at Merton College, Oxford, where he earned his BA in classics. He was private secretary to liberal politician Sir Thomas Dyke Acland, 11th Baronet, Thomas Acland in 1897, and the next year (as in 1898 Thomas Acland died) he first joined Royal Botanic Gardens, Kew, Kew as private secretary to the director, William Turner Thiselton-Dyer, W. T. Thiselton-Dyer. He was then assistant for India in the herbarium from 1901 until his departure for Hong Kong in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinidiaceae
The Actinidiaceae are a small family (biology), family of flowering plants. The family has three genus, genera and about 360 species and is a member of the order Ericales. Distribution They are temperate and subtropical woody plant, woody vines, shrubs, and trees, native to Asia (''Actinidia'' or kiwifruit, ''Clematoclethra'', and ''Saurauia'') and Central America and South America (''Saurauia'' only). ''Saurauia'', with its 300 species, is the largest genus in this family. Although now confined to Asia and tropical Central and South America, evidence indicates in the past the family had a wider distribution. The now extinct genus ''Parasaurauia'' is thought to have belonged to the Actinidiaceae and lived in North America during the early Campanian. Characteristics The plants are usually small trees or shrubs, or sometimes vines (''Actinidia''). The alternate, simple, spiral Leaf, leaves have serrated or entire margins. They lack stipules or are minutely stipulated. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop Wild Relative
A crop wild relative (CWR) is a wild plant closely related to a domesticated plant. It may be a wild ancestor of the domesticated (cultivated) plant or another closely related taxon. Overview The wild relatives of crop plants constitute an increasingly important resource for improving agricultural production and for maintaining sustainable agro-ecosystems. Their natural selection in the wild accumulates a rich set of useful traits that can be introduced into crop plants by crossing. With the advent of anthropogenic climate change and greater ecosystem instability CWRs are likely to prove a critical resource in ensuring food security for the new millennium. It was Nikolai Vavilov, the Russian botanist who first realized the importance of crop wild relatives in the early 20th century. Genetic material from CWRs has been utilized by humans for thousands of years to improve the quality and yield of crops. Farmers have used traditional breeding methods for millennia, wild maize ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiwifruit
Kiwifruit (often shortened to kiwi), or Chinese gooseberry, is the edible berry (botany), berry of several species of woody vines in the genus ''Actinidia''. The most common cultivar group of kiwifruit (Actinidia chinensis var. deliciosa, ''Actinidia chinensis'' var. ''deliciosa'' 'Hayward') is oval, about the size of a large Egg (food), hen's egg: in length and in diameter. Kiwifruit has a thin, fuzzy, fibrous, tart but edible, light brown skin and light green or golden flesh with rows of tiny, black, edible seeds. The fruit has a soft texture with a sweet and unique flavour. Kiwifruit is native to central and eastern China, with the first recorded description dating back to the 12th century during the Song dynasty. In the early 20th century, cultivation of kiwifruit spread from China to New Zealand, where the first commercial plantings took place. It gained popularity among British and American servicemen stationed in New Zealand during World War II, and later became c ...

Actinidia
''Actinidia'' is a genus of woody and, with a few exceptions, dioecious plants native to temperate eastern Asia, occurring throughout most of China, Taiwan, Korea, and Japan, and extending north to southern areas of Russian Far East and south into Indochina. The genus includes shrubs growing to tall, and vigorous, strong-growing vines, growing up to in tree canopies. They mostly tolerate temperatures down to around , and some are much hardier. The leaves are alternate and simple, with a dentated margin and a long petiole. The flowers are solitary or in axillary cymes, usually white, with five small petals. Most of the species are dioecious with separate male and female plants, but some are monoecious. The fruit is a large berry containing numerous small seeds; in most species, the fruit is edible. In particular, this genus is known for the taxon ''Actinidia chinensis'' var. ''deliciosa'', one of the most common cultivated kiwifruits, and for the hardy ornamental '' Act ...

Endemic Flora Of China
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a la ...

Flora Of Hubei
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...
