Varieties of bee pollinated cucumbers for the greenhouse

All gardeners know that cucumbers are divided according to the method of pollination into several types. Bee pollinated varieties grow well in temperate climates in open ground. Sudden cold snaps are dangerous for them, which make insects disappear for a while. But more and more questions related to the cultivation of these varieties in greenhouses. As you know, insects are difficult to lure into the greenhouse. Is it possible to grow a rich crop of such varieties in protected ground? More talk about it.

Ways to pollinate cucumbers

To understand how the process of pollination, it is enough to recall a few paragraphs of the textbook on botany. Cucumber flowers are divided into two types:

  • women;
  • man's.

They participate in pollination, without which it is impossible to get a rich harvest. The ovary is formed when the male plant cells reach the female, and this plant cycle is extremely important. Breeders also propose to achieve pollination in a different way, without the participation of male flowers. Thus, according to the method of pollination today, we can divide all cucumbers into three types:

  • pollinated by insects (mostly bees);
  • self-pollinated;
  • parthenocarpic.

Self-pollinated varieties can also be counted among parthenocarpic varieties, the meaning will not change. In such hybrids either predominantly female flowers will be present, or the pistil and stamen will simultaneously have a flower.

Bee pollinated cucumbers can only be pollinated in a natural way, which limits their cultivation in greenhouses. Yes, it is possible, but it will require a little more time and effort from the gardener. But these varieties have several advantages.

Benefits of bee pollinated cucumbers

To date, the selection of seeds is based on:

  • taste;
  • the method of pollination;
  • maturation rates;
  • yield varieties.

And if, during the formation of the ovary, parthenocarpic hybrids are very capricious with temperature drops, then this factor does not play a role for the bee-pollinated. One "but": a temporary cooling can scare off insects. If the process of pollination went smoothly, then the plants pollinated by insects, will give a big harvest.

Growing under greenhouse conditions

Consider the possibility of growing exactly bee-pollinated cucumber varieties in the greenhouse. Not everyone knows that this process is quite possible, although it can be fraught with a number of problems. However, our gardener is not afraid of complexity!

Considering all phases of the process from planting seeds to harvest, it should be noted that the most important step will be the process of pollination.

The process of pollination in the greenhouse

Experienced gardeners know that pollination can be achieved in a greenhouse in two ways (if, of course, non-pollinated varieties are planted):

  1. With the help of insects.
  2. With the help of artificial pollination.

If the weather is warm and sunny, the doors of the greenhouse are flung open, attracting bees, this is the first way. And if he is very doubtful, then the second is preferable. It is difficult to attract insects to the greenhouse. They are reluctant to fly open doors even to the open. Moreover, even if several bees get inside, no one can guarantee that they will cope with their task perfectly. Therefore, more often resort to the second method. Cucumbers will give a rich harvest, if done correctly.

Some theory

So, as mentioned earlier, the flowers are divided into male and female. In order to conduct artificial pollination, you will need to take a brush for drawing and spend enough time.

Important! For artificial pollination in the greenhouse, you must have both female and a sufficient number of male flowers.

Learn in advance to distinguish two inflorescences from each other. Make it very easy. Below the photo shows two flowers, and immediately catches the eye, what is the difference between them.

  • Male-type flowers are usually located in the leaf sinuses in the lower part of the plant and grow in groups;
  • female flowers grow separately, under each of them you can see a small ovary, similar to a small cucumber.

For clarity, we offer to see a short video. It will help you to finally understand how to distinguish one species from another.

Possible problems

Not everything can always go smoothly. Remember that bee-pollinated cucumbers, regardless of the variety, need both the presence of male flowers and the presence of female flowers. Sometimes it happens that men have already grown, and women have not had time to take shape. There is a real problem, which is called empty land.

To deal with this problem can and should be! Cucumber flowers open just a day, and pollination must be done as soon as possible. The cause of barren flowers can be:

  • poor quality of purchased seeds;
  • improper cultivation (cucumbers love moisture, sun and heat);
  • lack of top dressing;
  • rejection of pinching;
  • improper selection of varietal seeds yourself.

If you buy seeds in a store, give preference to proven producers. If you select seeds yourself, remember:

  • From hybrids of a new high-quality harvest will not work;
  • one must be able to distinguish the male fruits of cucumbers from the female ones.

A female cucumber of any kind has four seed-chambers, and a male cucumber has three. For the harvest to be of high quality, the seeds must lie down for at least 2-3 years before planting.

If you create a seedling of the right climatic conditions, in time to pinch and feed, the empty color does not threaten you.

Topping

Regardless of whether you grow bee pollinated cucumbers in open ground or in a greenhouse, you must give an impetus to the growth of lateral shoots. This rule applies to both early varieties and later varieties. The difference is insignificant:

  • for early varieties, pinch the main shoot through 8-10 leaves;
  • For later varieties, it is necessary to do this after 6-8 leaves.

Additionally, you remove the thick growths and allow the plant to give all its strength to the offspring, and this is also a big plus.

Bee pollinated varieties for greenhouses

Among the bee-pollinated varieties there are those that are very loved by gardeners. Try to plant such cucumbers in a greenhouse and go through the whole process from beginning to end. Consider several varieties that are considered sales hits:

  • early ripe variety "Competitor" (you can get offspring from it yourself);
  • early hybrid "Murashka";
  • hybrid Springwell;
  • ultra-fast hybrid Ajax.

We have listed them in a small comparison table for detailed information. Check it out.

Conclusion

Growing bee-pollinated cucumbers on their own in a greenhouse is a big job that will be rewarded with a rich harvest. Cucumbers have always been the number one vegetable in Russia, their popularity is only growing every year. Of course, it will be a little easier with parthenocarpic varieties, but what you choose in the end is up to you.
