On peut galement consommer les jeunes fruits verts la manire des courgettes. The term "pepo" is used primarily for Cucurbitaceae fruits, where this fruit type is common, but the fruits of Passiflora and Carica are sometimes also pepos. [46] In C.foetidissima, a weedy species, plants younger than 19 days old are not able to sprout from the roots after removing the shoots. Cucurbita pepo es el nombre cientfico de una especie de plantas cucurbitceas originaria de Mesoamrica y sur de Estados Unidos, que junto con otras especies emparentadas (Cucurbita maxima, C. moschata, C. argyrosperma) forman un grupo de especies de calabazas cuyas variedades cultivadas, de las que se cosecha su fruto maduro o inmaduro, poseen usos [105], Species in the genus Cucurbita are susceptible to some types of mosaic virus including: cucumber mosaic virus (CMV), papaya ringspot virus-cucurbit strain (PRSV), squash mosaic virus (SqMV), tobacco ringspot virus (TRSV),[113] watermelon mosaic virus (WMV), and zucchini yellow mosaic virus (ZYMV). Kabaczek Within the United States, the states producing the largest amounts are Florida, New York, California, and North Carolina. Les feuilles, alternes, simples, arrondies, sont pileuses mais douces au toucher. [20] Some cross pollinations can occur: C.pepo with C.argyrosperma and C.moschata; and C.maxima with C.moschata. TRAINS As in C. pepo, plants exist with a "bush habit" that is particularly evident in young plants, but older plants grow in the wild-type vining manner.. Arikara squash is an heirloom variety of C. maxima.Fruits weigh from four to eleven pounds. The shape of the fruit can be tear-drop or round, and they are colored in a C.argyrosperma has ovate-cordate (egg-shaped to heart-shaped) leaves. Un article de Wikipdia, l'encyclopdie libre. [27] Many North and Central American species are visited by specialist pollinators in the apid tribe Eucerini, especially the genera Peponapis and Xenoglossa, and these squash bees can be crucial to the flowers producing fruit after pollination. C.moschata can intercross with all the others, though the hybrid offspring may not themselves be fertile unless they become polyploid. argyrosperma (v2) and a new genome assembly Annotation classification and pathway enrichment analysis of differentially expressed genes KEGG. [citation needed]The stem is normally divided into nodes and internodes: The nodes hold one or more [35][42], The plant hormone gibberellin, produced in the stamens, is essential for the development of all parts of the male flowers. Le potiron est largement cultiv comme plante potagre pour son fruit comestible maturit. It is known to have appeared in Missouri, United States, at least 4,000 years ago. Wild Cucurbita peduncles are always below this 10mm barrier. pepo, called summer squash.. Some authors maintain that C. pepo is derived from C. texana, while others suggest that C.

[47], Experiments have shown that when more pollen is applied to the stigma, as well as the fruit containing more seeds and being larger (the xenia effect mentioned above), the germination of the seeds is also faster and more likely, and the seedlings are larger. [5], C.foetidissima contains a saponin that can be obtained from the fruit and root. [9] Cucurbita species are some of the most important of those, with the various species being prepared and eaten in many ways. BLAST [5] The carbohydrates that are formed in the tap root have led to the idea of growing the plant for biofuel.[6][7]. Disclaimer: The NCBI taxonomy database is not an authoritative source for nomenclature or classification - please consult the relevant scientific literature for the most reliable information. [1] The type specimen was collected from Mexico by Alexander von Humboldt and Aim Bonpland sometime before 1817. [71][72][73] No species within the genus is entirely genetically isolated. 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. Summer squash, presently the most common group of cultivars, origin is recent (19th century), semi-shrubby, cylindrical fruit with a mostly consistent diameter, This page was last edited on 29 October 2022, at 12:04. Assorted cultivars, from top-left, clockwise: winter squash, both a shrubby and creeping plant, obovoid or conical shape, pointed at the apex and with longitudinal grooves, thus resembling a spinning top.

Pages pour les contributeurs dconnects en savoir plus, Sommaire [19] These eight edible cultivated varieties of C. pepo vary widely in shape and color,[10][20][21] and one inedible cultivated variety:[22], Due to their varied genetic background, members of C. pepo vary widely in appearance, primarily in regards to their fruits. The shape of C.pepo leaves varies widely. The word vegetable was first recorded in English in the early 15th century. Les feuilles, alternes, simples, arrondies, sont pileuses mais douces au toucher. summer squash. [10][12][13][14], It is found from sea level to slightly above 2,000m (6,600ft). [10][11] Germination temperature range is between 15C and 37C with an optimum at 25C. Plant Soil 2001, 235, 95-103. Il s'coule six mois entre le semis et la rcolte. Other kinds of gourd, also called Le terme dsigne aussi ce fruit consomm comme lgume ou donn aux animaux. La leve est complte aprs neuf jours. The starch content in the dried root is between 47.5%. [89] This bitterness is especially prevalent in wild Cucurbita; in parts of Mexico, the flesh of the fruits is rubbed on a woman's breast to wean children.

Cucurbita maxima. The development of female flowers is not yet understood. [44], Seeds with maximum germination potential develop (in C.moschata) by 45 days after anthesis, and seed weight reaches its maximum 70 days after anthesis. Les diverses espces de courges ont souvent t confondues entre elles, et mme avec les gourdes (Lagenaria) dj connues en Europe depuis l'Antiquit. Tous les potirons se reproduisent par semis.

Neotrpico - Wikipedia, la enciclopedia libre Cucurbita (Latin for gourd)[3][4] is a genus of herbaceous fruits in the gourd family, Cucurbitaceae (also known as cucurbits or cucurbi), native to the Andes and Mesoamerica. Las cucurbitceas (Cucurbitaceae) son una familia de plantas tpicamente trepadoras por zarcillos, en general herbceas y gefitas o anuales, con el ovario nfero y el fruto inmaduro de un pepnide, que al madurar se diversific adaptndose a diferentes sndromes de dispersin.Producen cucurbitacinas que hacen que partes vegetativas y frutos inmaduros, y a Cucurbita maxima. [126] In France, marrows (courges) are traditionally served as a gratin, sieved and cooked with butter, milk, and egg, and flavored with salt, pepper, and nutmeg,[127] and as soups. Many cultivars of Cucurbita maxima have been developed. [41] Ethephon, a plant growth regulator product that is converted to ethylene after metabolism by the plant, can be used to increase fruit and seed production. Plant Soil 2001, 235, 95-103. Lagenaria siceraria 070993-- Pumpkins, squash and gourds (Cucurbita spp.) Cucurbita maxima, one of at least four species of cultivated squash, is one of the most diverse domesticated species. [70] Recent genomic studies support the idea that the Cucurbita genus underwent a whole-genome duplication event, increasing their number of chromosomes and accelerating the rate at which their genomes evolve compared to other cucurbits. 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.
