The recognized high nitrogen-fixing potential of this taxon is linked with the presence of numerous nodules during the rainy season, located near the raddiaja m and between 25 and 75 cm in depth in natural conditions. Views Read Edit View history.
The studies presented in this book naturally do not claim to be exclusive.
Acacia raddiana – Wikispecies
A number of rsddiana have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Click here to download Flash player. It is characterized by ecological plasticity, and colonises regions receiving between 50 and 1 mm of annual rainfall and located at altitudes of up to 2 m.
Several hundred combinations in Acacia were published by Pedley in Elsewhere they may be dominant, as in the Brigalow BeltMyall woodlands and the eremaean Mulga woodlands. Retrieved 15 November However these were not upheld with the retypification of Acacia. Acacia is awarded a place of honor alongside the cedar in the consolation prophecies: Missouri Botanical Garden Press. Retrieved 22 November Vachellia tortiliswidely known as Acacia tortilis but attributed by APG III to the genus Vachellia is the umbrella thorn acaciaalso known as umbrella thorn and Israeli babool a medium to large canopied tree native primarily to the savanna and Sahel of Africa especially Sudanbut also occurring in the Middle East.
Xcacia is also used to tan hides and the gum it produces eaten. Spread over such a large area inhabited by diverse cultures, the V. The range of seed-eating coleoptera that are parasites of the Acacia raises questions that need answering concerning the trophic and ecological specialization of acadia, identification of defence mechanisms used by Acacia, and the characterisation of co-evolution of the insects and the host plant.
Petal or tepal color: It also became apparent that mycorrhizal infection of the provenances of Acacia raddiana north of south were similar. It is prevalent in the suitable places, is prominent in the landscape and holds a dominant position in its ecosystem.
It is true that the genetic study raddinaa this species is hampered by its polyploidy, which underlines the need for improvement of genetic models that are suitable for the interpretation of tetrapoloid markers. There are numerous benefits to be had from such plant formations, in particular for the conservation of biodiversity in its widest sense: Australian botanists proposed that this would be more disruptive than setting a different type species A.
There follows a brief summary of some of the future research topics suggested by the different contributions. As far as micro-organisms are concerned, confirmation is needed of the different groups of strains of Rhizobium nodulating Acacia raddiana using phylogenetic techniques to determine their taxonomic position and aczcia suggest possible final nomenclature.
Archived from the original on 10 November The causes are to be found on the one hand in unfavourable climatic changes, and on the other, in increasing human activity. Views View Edit History. Our results show that there is no apparent link between the taxonomic position and the geographic origin of the strains of rhizobia that incidentally display marked homogeneity in their main symbiotic characteristics.
HaynePurdue University, December Umbrella thorn acacia Specimen of the nominate subspecies in Serengeti National Park Scientific rraddiana Kingdom: The following other wikis use this file: Timber from the tree is used for furniturewagon wheels, fence postscagesand pens.
Initially it comprised a group of plant species native to Africa and Australia, with the first species A. From Wikipedia, the free encyclopedia. In another connection, it will be useful to improve our knowledge of the diversity and the ecology of arbuscular mycorrhizial fungi in the soil in order to select the most efficient as innoculum.
The use of clones could considerably help this selection process. Summary [ edit ] Description Acacia raddiana in Bouhedma – Fruits. The plant can be classified among species with high nitrogen fixing potential and low yield.
