Flowering of cucumbers occurs in several ways: female, male and hermaphroditic. Yield depends on flowering, so you need to distinguish between flowering types.

Female flowering type
Note that the flowers of a female type of cucumber are characterized by an ovary, or rather a small cucumber. from the male type even before the onset of flowering. Parthenocarpic form an ovary of green leaves, without signs of pollination. It is safe to say that this type of flowering does not need the help of bees or other pollinated insects.
In order for bee pollinated cucumbers to form ovaries and formed a fetus, pollination by pollen of the peasant type should be performed. The following moments of flower formation exist:
- long-fruited hybrids are characterized by the fact that no more than 2 female flowers can form in their 1 node;
- bunch cucumbers can form about 10 in 1 node female flowers.
Causes of developmental disruption
Quite often you can observe a situation when female flowers develop longer than male flowers.There are several reasons for this.
- These are the characteristics of the variety. Most of the varieties of cucumbers initially form a male flower, located on the main stem and only then on the side shoots of a female appearance. This threatens that fertilization will be delayed indefinitely and the crop will have to be harvested much later.
- The reason lies in the seed quality. Young seeds always form the girlish type first and only then the male type. If the seeds are characterized by an age of about 2 years, then the formation of flowering of both sexes occurs simultaneously. This allows you to speed up the process of fetal formation.
Male flowering type
The stamen flowering type is characterized by the fact that it does not contain ovaries. A description of their appearance indicates that the flowers are yellow and are located on a peduncle of large length. If we consider male flowers from the point of view of the biological component, then their main purpose is pollination of female flowers, after which the formation of the fetus occurs. Pollination is necessary so that the fruits can form. This means that the crop will ripen in a short time.
Parthenocarpic cucumber grows without pollination. But, in this case, they completely lack seeds. In order to be able to collect seeds, parthenocarpic inflorescences must be constantly pollinated by male pollen.
The description indicates that male inflorescences most often begin to form on the main stem or lateral shoots. It is believed that most of this formation occurs in beams. The pollen of the male inflorescence is quite heavy. Despite this, it does not fall out of the main flower, because the stickiness characteristic very strongly holds it in place. For this reason, the wind cannot spread pollen, and pollination is possible only with the help of bees or other insects.
Hermaphroditic type of flowering
The hermaphroditic look is the male and female flowers of a cucumber in one inflorescence. It is characterized by ovaries of short length. From such an ovary, most often, cucumbers appear, presented in a spherical shape. The description indicates the fact that hermaphrodite contains both pistils and stamens. Such inflorescences can be either self-pollinated or pollinated by insects. Same-sex flowers can also be my characteristics.
- Andromonotius type. It includes bisexual features, where the male type prevails.
- Gynomono-type type. It is characterized by the fact that it contains hermaphroditic inclinations, in most of the female structure.
The main feature of this type is that its flowers are bisexual.Some experts convince farmers with confidence that the first varieties of cucumbers were hermaphrodites. It was from them that the division into female and male types of flowering began to occur. Most people try not to use plants of this type for growing for sale. Such plants gained great popularity only among breeders who are trying to create new varieties of cucumbers.
How the flowers look
The male inflorescence has cups, stamens and a corolla. If you are wondering how many stamens this species contains, there are only 5. There is anther on each of them, in which pollen is stored.
Female inflorescences have a pistil. They do not possess stamens. Pestle consists of several main parts: ovary, pillar and stigma. The lower part usually has 3 slots.
The pollination process
The formula for the pollination process is simple. Pollen must necessarily get into the eggs that are located in the ovules. After this, there is little time before of how the ovaries begin to form.The parthenocarpic species can form the ovaries without percent pollination poll.
Pollen has ideal parameters for pollination only before lunchtime. After this period, it begins to lose its vitality. If the color of the female inflorescence has a saturated color, then it is completely ready for pollination. If the process has not occurred, then after a few days the color becomes paler.
After describing all the features, it is clear that the type of flowering determines not only the external type of bush, but also the timing for which the fruit ripens. As the experience of many experts shows, one should give preference to parthenocarpic female plants, because in this case it is possible to harvest much earlier.
