Self-pollination is a form of pollination in which pollen arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms) of the same plant. The term cross-pollination is used for the opposite case, where pollen from one plant moves to a different plant.
The zucchini (/ z u ˈ k iː n i / ⓘ; pl.: zucchini or zucchinis), [1] courgette (/ k ʊər ˈ ʒ ɛ t /) or baby marrow (Cucurbita pepo) [2] is a summer squash, a vining herbaceous plant whose fruit are harvested when their immature seeds and epicarp (rind) are still soft and edible.
Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [1] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives ...
Pollination also requires consideration of pollenizers, the plants that serve as the pollen source for other plants. Some plants are self-compatible (self-fertile) and can pollinate and fertilize themselves. Other plants have chemical or physical barriers to self-pollination.
Hand-Pollinate Flowers. Fruiting plants like tomatoes, cucumbers, and peppers are pollinated by insects or the wind in outdoor gardens. But if you want to grow these plants indoors, ...
Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell present. Self-pollination can either be done completely autogamously or geitonogamously. In the former, the egg and sperm ...
Cucurbita female flower with pollinating squash bees. All species of Cucurbita have 20 pairs of chromosomes. [15] 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 ...
Growing marrow Flower of marrow. A marrow is the mature fruit of certain Cucurbita pepo cultivars used as a vegetable. The immature fruit of the same or similar cultivars is called courgette (in Britain, Iran, Ireland, France, the Netherlands, Singapore, Malaysia and New Zealand) or zucchini (in North America, Japan, Australia, the Czech Republic, Italy, Germany and Austria).
