Parthenocarpic cucumber

Many truck farmers have heard about parthenocarpic hybrids and would like to know what this means.

What does "parthenocarpic cucumber" mean?

Parthenocarpic varieties of cucumbers tie fruit without pollination. If you cut along such a cucumber, you can see that there are no seeds in it. Along with seedless forms there are also plants where parthenocarpic fruits have a pear-shaped or hooked form, thickened in the place where the seeds are concentrated.

Advantages of parthenocarpic cucumbers

Parthenocarpic cucumbers have a number of advantages:

In the light of recent changes in nature, a significant plus is that the culture does not need pollination by bees and bumblebees, which is becoming less and less.

Growing parthenocarpic cucumbers

Parthenocarpic cucumbers are recommended to grow in a greenhouse . The matter is that hybrids grow in curves in the open ground. So, for growing on beds and in open greenhouses, where pollinators can freely fly, it is better to choose bee pollinated varieties.

Seeds of parthenocarpic cucumbers are sown in early December. Preliminary it is recommended to conduct thermal disinfection: warm up for 3 days at a temperature of +50 degrees, and then a day - at a temperature of +75 degrees. To accelerate growth, the seeds are soaked in an aqueous solution, to which 100 mg of boric acid, copper sulfate, manganese and zinc sulphates, and 20 mg of ammonium molybdate are added. Microelements are diluted in 1 liter of water, and the seeds are placed in the solution for 12 hours, after which they are well dried. The seeding depth is 2 - 2.5 cm. It is desirable to grow seedlings in peat pots without picks. 650 - 750 g of seeds are necessary for a greenhouse with an area of ​​1 hectare.

With the emergence of seedlings, it is necessary to provide electrical illumination. The temperature regime before emergence should be +27 degrees, after their appearance, a temperature of + 19 ... + 23 degrees in the daytime and not below +16 degrees at night is desirable. Watering is carried out with warm water by means of a sprinkler system.

In January, planting seedlings. By this time, the shoots should have 5 to 6 leaflets, a height of 25 to 32 cm and sufficiently developed roots. Plant the seedlings vertically. At the end of planting, watering the crops is performed. A few days later the bushes are tied to the trellis, so that the plant receives enough light. Regularly remove and pinch the side shoots. As the bushes outgrow the trellis, they form the top of the bush. For this, the plant is bent and fastened to the trellis , also without fail by pinching. Norm of watering Cucumber is at least 2 liters per 1 m2. Feed cucumbers under the root of complex water-soluble fertilizers. In the daytime, the air temperature should be +22 ... + 24 degrees, at night + 17 ... + 20 degrees. Low temperature and cold water cause death of the ovaries. The harvest of cucumbers begins to be harvested for 40 - 45 days from the time of transplanting. In a week usually spend 2 - 3 gathering of vegetables.

Almost all parthenocarpic varieties of cucumbers for greenhouses are not suitable for canning and pickling for the winter. But recently breeders brought out a new parthenocarpic hybrid F1 Zador, which is great for winter harvesting.

Recently, other parthenocarpic vegetables have become more popular: tomatoes, zucchini, etc., for the formation of ovaries, which do not require pollinators.
