Recently, when buying seeds, you can often see the inscription "parthenocarpic hybrid" on the package. Many people wonder what this concept means. Some gardeners claim that these are plants that self-pollinate. This is not true. Such plants produce fruits without pollination at all.
The concept of "parthenocarpic hybrid"
Customers at the seed shop often ask what a parthenocarpic hybrid means. When self-pollinating, a plant has both a pistil and a stamen, and it pollinates itself for the ovary of the fruit (for example, a tomato). In such a plant, the fruit has seeds. AND the fetus of the parthenocarpic hybrid has no seeds.
Such hybrids are convenient to grow in greenhouses, because insects do not fly there to pollinate flowers. Parthenocarpic cucumbers are most often grown.

Before planting, the seeds must be soaked in a special water solution saturated with useful trace elements. Then the seeds are thoroughly dried and placed in the soil no deeper than 2.5 cm. First, the seedlings germinate in peat cups.
As soon as the first shoots appear, you need to increase the amount of light. The air temperature should be at least +27 ⁰ C before the shoots appear, and after their germination, it must be lowered to +18 +23 ⁰ C. At night, the temperature should be reduced to +16 ⁰C.

When the seedlings have at least 6 leaves, they can be transplanted into the ground, most often after the New Year holidays. After a couple of days, the shoots should be tied to the trellis, since the plant is already in height reaches about 30 cm... Side shoots should be periodically thinned and pinched. This is necessary in order for the bushes to have good growth conditions.
Common cucumbers are pinched along the main stem in the region of 5-6 leaves. This cannot be done with a parthenocarpic plant, since it is along the main stem that the flower ovaries are located. Therefore, pinching should be done on the shoots.
