Why cucumbers are bitter: the main reasons

Studying the question, for what reason, the taste characteristics of cucumbers have changed, it is impossible to indicate for sure only one factor that influenced this, as a rule, this is a complex phenomenon. Did you know? Similar to how cucumber produces cucurbitacin for protection and survival, gourds secrete saponin - a substance that gives melons, pumpkins and watermelons a bitter taste. Answering the question of why the cucumber gains a bitter taste, we can say that the substance cucurbitacin is the reason for this. This is a toxic compound of organic elements that, with maximum accumulation, gives the fetus bitterness.

Its leaves are synthesized, after which it is distributed throughout the plant, accumulating in the peel and on the tips of the fruit, concentrating as much as possible in the roots. Cucurbitacin is necessary for the plant to naturally protect it from being eaten by animals until it stops bearing fruit and its seeds mature.

Under stress, the plant significantly increases the production of this substance. Most often, cucumber varieties with black spikes are bitter, while in white this effect is less pronounced.

How to remove bitterness from cucumbers

  1. Violation of the timing of sowing. The wrong planting period creates a stressful situation for the plant.

  3. The temperature of water for irrigation should not be cold, approximately + 25˚C and higher.
  4. In order for cucumbers to grow tasty, they must be fertilized by feeding with organic or complex additives, including potash, phosphorus and nitrogen (the latter should be brought with care, since their excess is also undesirable).
  5. You should not plant cucumbers in the garden too tightly, since a heap planting will not allow the fruits to get enough nutrients and they will be forced to survive.
  6. In the heat and under the scorching rays of the sun, it is difficult for a plant to grow, especially if it did not manage to adapt to such weather conditions gradually as a result of late planting. To create conditions for growth under diffused light, you can plant corn or sunflowers next to cucumbers, which will give a little desirable shadow.
  7. Low humidity as a result of dry, suffocating weather.

  11. It is not recommended to water the cucumbers from the hose, since under the influence of a strong pressure of water the roots of the bush can be exposed. It is better to use drip irrigation or irrigate a bed from a watering can under the root.
  12. As a result of pest control, a plant can begin to produce cucurbititacin to scare them away, so preventive spraying is necessary.

As a rule, bitter vegetables are more hollow and voluminous due to the abundance of tubercles.
