Cucumbers may also be pollinated via bumblebees and several other bee species. Most cucumbers that require pollination are self-incompatible, thus requiring the pollen of another plant in order to form seeds and fruit. [10] Some self-compatible cultivars exist that are related to the 'Lemon cucumber' cultivar. [10]
Similar to some types of cucumber, [10] these plants are monoecious, producing both male and female flowers on the same plant. [9] [11] Flowers are small and yellow, and are approximately 4 mm (0.2 in) in diameter. [5] Unusually for the cucurbits, the female flowers appear before the male flowers. [6]
Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [clarification needed] Differences in growth were detected early in ontogeny. The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by ...
Or, with bisexual and at least one of male and female flowers on the same plant. [2] Protandrous: (of dichogamous plants) having male parts of flowers developed before female parts, e.g. having flowers that function first as male and then change to female or producing pollen before the stigmas of the same plant are receptive. [6]
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.
The yellow or orange flowers on a Cucurbita plant are of two types: female and male. The female flowers produce the fruit and the male flowers produce pollen. 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.
The sole species is E. lobata, commonly called wild cucumber and prickly cucumber. It is an annual, sprawling plant that is native to North America . Sicyos angulatus , common name "bur cucumber", is an annual plant with a similar clinging vine growth but different-appearing flowers and seed pods.
In dimorphic sexual systems, individual plants within a species only produce one sort of flower, either hermaphrodite or male, or female. Dimorphic sexual systems include dioecy, gynodioecy, androdioecy, and trioecy. [7] Male (a.k.a. staminate) flowers have a stamen but no pistil and produce only male gametes. Female (a.k.a. pistillate) flowers ...
