In a seed batch with 90 percent germination rate, over 90 percent of the plants had sprouted after 29 days from planting.
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.
The typical cultivated Cucurbita species has five-lobed or palmately divided leaves with long petioles, with the leaves alternately arranged on the stem. All of the above-ground parts may be hairy with various types of trichomes, which are often hardened and sharp. The leaves of all four of these species may or may not have white spots. pedatifolia species groups are xerophytes, arid zone perennials with storage roots; the remainder, including the five domesticated species, are all mesophytic annuals or short-life perennials with no storage roots.
Spring-like tendrils grow from each node and are branching in some species. argyrosperma has ovate-cordate (egg-shaped to heart-shaped) leaves. There are male (staminate) and female (pistillate) flowers (unisexual flowers) on a single plant (monoecious), and these grow singly, appearing from the leaf axils. citrullus (watermelon, now Citrullus lanatus) and C. The taxonomy by Nee closely matches the species groupings reported in a pair of studies by a botanical team led by Rhodes and Bemis in 19 based on statistical groupings of several phenotypic traits of 21 species.
There is debate about the taxonomy of the genus, as the number of accepted species varies from 13 to 30. The fruits of the genus Cucurbita are good sources of nutrients, such as vitamin A and vitamin C, among other nutrients according to species.
The five domesticated species are Cucurbita argyrosperma, C. The fruits have many culinary uses including pumpkin pie, biscuits, bread, desserts, puddings, beverages, and soups. The first group are annual or short-lived perennial vines and are mesophytic, i.e.
pepo germinate best with eight hours of sunlight daily and a planting depth of 1.2 centimeters (0.47 in).
Seeds planted deeper than 12.5 centimeters (4.9 in) are not likely to germinate. foetidissima, a weedy species, plants younger than 19 days old are not able to sprout from the roots after removing the shoots.Most Cucurbita species are herbaceous vines that grow several meters in length and have tendrils, but non-vining "bush" cultivars of C. The female flowers produce the fruit and the male flowers produce pollen. All of these can be treated as winter squash because the full-grown fruits can be stored for months; however, C.Many North and Central American species are visited by specialist bee pollinators, but other insects with more general feeding habits, such as honey bees, also visit. pepo includes some cultivars that are better used only as summer squash.Within the United States, the states producing the largest amounts are Florida, New York, California, and North Carolina.As an example of Curcubita, raw summer squash is 94% water, 3% carbohydrates, and 1% protein, with negligible fat content (table).By 2012, Iran had moved into the 5th slot, with Egypt falling to 6th.
