To learn more about the meaning of various cancer classification descriptors listed in this fact sheet, please visit the appropriate reference, or call NPIC. It comes from Old French, and was originally applied to all plants; the word is still used in this sense in biological contexts. By c.8,000 years BP the C.pepo peduncles found are consistently more than 10 millimeters (38in) thick. [69] Modern-day cultivated Cucurbita are not found in the wild. Many cultivars of Cucurbita maxima have been developed. [5] At the time of the Spanish invasion, it was found growing in these areas and has never since been found elsewhere except as evidently carried by humans. [6] Genetic studies of the mitochondrial gene nad1 show there were at least six independent domestication events of Cucurbita separating domestic species from their wild ancestors. Most species do not readily root from the nodes; a notable exception is C.ficifolia, and the four other cultivated mesophytes do this to a lesser extent. [101], Cucurmosin is a ribosome inactivating protein found in the flesh and seed of Cucurbita,[102][103] notably Cucurbita moschata. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo.They also generally display a greater resistance to disease and insects, especially to the squash vine borer. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo.They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Summer squash, shrubby plant, with yellow or golden fruit and verrucose rind, similar to var. [144], Cucurbita have been used in various cultures as folk remedies.

Ce sont tous deux des cucurbitaces, autrement dit, des courges. The shape of the fruit can be tear-drop or round, and they are colored in a Cucurbita pepo is a cultivated plant of the genus Cucurbita.It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp.

[24] Within C. pepo, the pumpkins, scallops, and possibly crooknecks are ancient and were domesticated separately. Some authors maintain that C. pepo is derived from C. texana, while others suggest that C. [78][79] Solid evidence of domesticated C.pepo was found in the Guil Naquitz cave in the form of increasing rind thickness and larger peduncles in the newer stratification layers of the cave. Random amplified polymorphic DNA has proven useful in sorting out the relationships of the C. pepo species, varieties, and cultivars, showing that few, if any, modern cultivars have their origins with C. texana. Le ptisson se distingue des autres courges par son fruit de forme aplatie, circulaire, plus ou moins conique et prsentant sa priphrie des bosses plus ou moins marques, formant parfois des sortes de cornes redresses.. Il en existe plusieurs varits. The family Cucurbitaceae has many species used as human food. CuGenDBv2 is up running.Version 1 of CuGenDB will be still live but will not be updated [Apr, 2022] SNPs called from GBS data of 2083 melon accessions are now freely available. Other kinds of gourd, also called Lagenaria is a genus of gourd-bearing vines in the squash family (Cucurbitaceae). Sixteen of the 21 species were grouped into five clusters with the remaining five being classified separately:[27][28], The full phylogeny of this genus is unknown, and research was ongoing in 2014. It comes from Old French, and was originally applied to all plants; the word is still used in this sense in biological contexts. Seeds planted deeper than 12.5 centimeters (5in) are not likely to germinate. [16][19] All but a few C. pepo cultivars can be included in these groups. Histoire. [5], C.foetidissima contains a saponin that can be obtained from the fruit and root. [3][61][106] Ingesting too much cucurbitacin can cause stomach cramps, diarrhea and even collapse. The best-known species, the calabash or bottle gourd, L. siceraria, has been domesticated by humans, and has spread beyond Africa.The other species are not cultivated. [135] Also, in 2001 depictions of this genus were identified in Grandes Heures of Anne of Brittany (Les Grandes Heures d'Anne de Bretagne), a French devotional book, an illuminated manuscript created between 1503 and 1508. The paper describing these data is published in Molecular Horticulture. Changes in fruit shape and color indicate that intentional breeding of C.pepo had occurred by no later than 8,000 years BP. The paper describing these data is published in Molecular Horticulture. [4] Only long-vining plants are known in this species. It has been domesticated in the Americas for thousands of years. [31] Species native to North America include C.digitata (calabazilla),[74] and C.foetidissima (buffalo gourd),[75] C.palmata (coyote melon), and C. It is grown in a wide altitudinal range: from sea level to as high as 1,800 meters (5,900ft) in dry areas, usually with the use of irrigation, or in areas with a defined rainy season, where seeds are sown in May and June. pepo. A stem is one of two main structural axes of a vascular plant, the other being the root.It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
