Unusually for the cucurbits, the female flowers appear before the male flowers. [6] These plants can pollinate themselves, but the individual flowers are not self-fertile. Each plant can produce hundreds of fruits, [8] which develop at the base of the female flowers (the ovaries are inferior). [12] Fruits are olive-shaped, [5] grow to 2.5–4 ...
Few plants self-pollinate without the aid of pollen vectors (such as wind or insects). The mechanism is seen most often in some legumes such as peanuts. In another legume, soybeans, the flowers open and remain receptive to insect cross pollination during the day. If this is not accomplished, the flowers self-pollinate as they are closing.
The cucumber (Cucumis sativus) is a widely-cultivated creeping vine plant in the family Cucurbitaceae that bears cylindrical to spherical fruits, which are used as culinary vegetables. [1] Considered an annual plant, [ 2 ] there are three main types of cucumber—slicing, pickling , and seedless —within which several cultivars have been created.
Self-pollinating, self-fertilizing – in flowering plants awn 1. Any long, bristle-like appendage. 2. In the Poaceae, an appendage terminating or on the back of glume s or lemma s of some grass spikelet s. 3. In the Geraniaceae, the part of the style that remains attached to the carpel that separates from the carpophore (column). 4.
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 ...
About 10–15% of flowering plants are predominantly self-fertilizing. [9] 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 ...
Three kinds of cucumbers: Sikkim, Armenian, and lemon. This is a list of varieties or cultivars of cucumber, a widely cultivated vine in the gourd family, Cucurbitaceae. The cucumber vine bears edible fruit. A lemon cucumber
One particularly interesting case is the Prunus SI systems, which functions through self-recognition [15] (the cytotoxic activity of the S-RNAses is inhibited by default and selectively activated by the pollen partner SFB upon self-pollination), [where "SFB" is a term that stands "for S-haplotype-specific F-box protein", as explained ...
