Marigoule (hybrid)
Marigoule is the name of a french hybrid of chestnut (synonym M.15 or CA 15), cross between a European chestnut (Castanea sativa) and Japanese (Castanea crenata). In 1986, it originated from a Migoule orchard in Ussac in Corrèze. Marigoule (a contraction of Marron of Migoule) is a very tasty chestnut. It should be planted in rather low altitude in very sunny areas and protected from the wind (up to 300 m elevation for South-West orchard orientation or up to 400 m elevation in South-East orchard orientation). Otherwise its productivity remains small. In France, it is grown mainly South of the Dordogne and Lot-et-Garonne for the fresh market production because of the nuts beautiful appearance. Culture As rootstock, it is graft incompatible with many varieties but compatible with Precoce Migoule, Maridonne, Bournette, Fertil, Sauvage Marron, Precoce Monteil and Sucquette. Marigoule has medium quality pollen. This cultivar can be a pollinator for most of the pollen sterile chest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanea Sativa
''Castanea sativa'', the sweet chestnut, Spanish chestnut or just chestnut, is a species of tree in the family Fagaceae, native to Southern Europe and Asia Minor, and widely cultivated throughout the temperate world. A substantial, long-lived deciduous tree, it produces an edible seed, the chestnut, which has been used in cooking since ancient times. Description ''C. sativa'' attains a height of with a trunk often in diameter. Around 20 trees are recorded with diameters over including one in diameter at breast height. A famous ancient tree known as the Hundred Horse Chestnut in Sicily was historically recorded at in diameter (although it has split into multiple trunks above ground). The bark often has a net-shaped (retiform) pattern with deep furrows or fissures running spirally in both directions up the trunk. The trunk is mostly straight with branching starting at low heights. The oblong-lanceolate, boldly toothed leaves are long and broad. The flowers of both sexe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canker
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium '' Pseudomonas savastanoi'', rather than ''Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytophthora
''Phytophthora'' (from Greek language, Greek (''phytón''), "plant" and (), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental degradation, environmental damage in natural ecosystems. As well as impacting large scale agriculture, ''Phytophthora'' is a nuisance to garden and indoor plant hobbyists as well as bonsai artists. The cell wall of ''Phytophthora'' is made up of cellulose. The genus was first described by Anton de Bary, Heinrich Anton de Bary in 1875. Approximately 170 species have been described, although 100–500 undiscovered ''Phytophthora'' species are estimated to exist. Pathogenicity ''Phytophthora'' species, spp. are mostly pathogens of dicotyledons, and many are relatively host-specific parasites. ''Phytophthora cinnamomi'', though, infects thousands of species ranging from club mosses, ferns, cycads, coni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castanea Crenata
''Castanea crenata'', the Japanese chestnut, also known as the Korean chestnut is a species of chestnut native to Japan and Korea. ''Castanea crenata'' exhibits resistance to ''Phytophthora cinnamomi'', the fungal pathogen that causes ink disease in several Castanea species. The mechanism of resistance of ''Castanea crenata'' to ''Phytophthora cinnamomi'' may derive from its expression of the Cast_Gnk2-like gene. Description ''Castanea crenata'' is a small to medium-sized deciduous tree growing to 10–15 m tall. The leaves are similar to those of the sweet chestnut, though usually a little smaller, 8–19 cm long and 3–5 cm broad. The flowers of both sexes are borne in 7–20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3–7 brownish nuts that are shed during October. Cultivation and uses ''Castanea crenata'' is ...

Precoce Migoule (chestnut)
The Precoce Migoule is a chestnut hybrid (CA 48), a natural cross between a European chestnut (Castanea sativa) and a Japanese chestnut (Castanea crenata). It was discovered by J. Dufrenoy at the orchard of Migoule in Brive-la-Gaillarde. The tree is vigorous and erect growing with growth of a metre (3 ft) or more in a season if the conditions are right. It is a large sized chestnut tree with height reaching 20 m (60 ft) or more and 7.5-10 m (25-35 ft) wide. Trees start to bear after 3 to 5 years. Full nut production in 12 - 20 years depending on the location. This hybrid can be grown in many areas where grapes are grown. It is cold hardy to -28C (-20F In an orchard with South West orientation it can be grown up to 500 m (1640 ft) elevation. It is an early ripening variety - great for northern climates where late ripening varieties can get damaged by frost - a very dependable producer in cool region It blooms early and is frost sensitive but can produce nuts from secondary ...
