The old people in the countryside say that the cucumber that has been stepped on will be bitter, but in fact, there is a basis for this. The cucumber is stepped on, and the melon vine is harmed, so the cucumber will become bitter.
The main reasons for the bitterness of cucumbers are as follows:
The first is atavism. At first, cucumbers were bitter, and for this reason, the ancestors of cucumbers were also known as bitter cucumbers. The bitter taste of cucumber is due to the fact that it contains - glucoside, which is a bitter substance, and it is also present to protect its seeds from being eaten by other animals, which is conducive to reproduction.
During the long-term cultivation process of humans, the bitter taste of cucumbers is gradually reduced by artificial selection until the bitterness disappears. However, cucumbers are still bitter when they are not ripe, especially in cucumber stems, where the bitterness is still very strong because there are more glycosides. Cucumbers are also a domesticated species.
Sometimes the cucumber seeds purchased by farmers are not pure enough or the generations are not separated enough, and the cucumbers may also have atavism, resulting in the bitter taste of the cucumber.
The second is the temperature, humidity, fertilizer and other problems of growing cucumbers. During cucumber growing, too much moisture, insufficient light, or persistently cold and rainy weather can cause cucumbers to develop a bitter taste, but when the weather improves, the bitterness disappears. In addition, hot weather and excessive application of nitrogen fertilizer may also cause cucumbers to produce more bitter substances, resulting in bitter cucumbers.
Thirdly, because of external reasons, the root of the cucumber is damaged, which can also lead to the bitter taste of the cucumber. Cucumber stems contain more cellulose and lignin. The stem is relatively brittle and has some toughness, and there are many hollow structures on the stem.
Once you step on the vine of the cucumber, the melon vine is injured, and the cucumber will accumulate a lot of nutrients and organic matter to heal the wound, resulting in a bitter taste of the cucumber. In this way, it is really possible to grow cucumbers with a bitter taste, which shows that there is a certain scientific basis for the elderly in rural areas to say that cucumbers that have been stepped on will be bitter.

There is also a popular saying that young people in rural areas do not take care of the elderly, and many young people have acquiesced in their hearts, that is: in order to serve the elderly at home, they are forced to live in the countryside, resulting in a mess of their lives, and may even be dragged down by the old people in the family, which is not worth it and cannot be done. Nowadays, the practice of many young people in rural areas is to have spare money, give it to their parents, and if they have no spare money, they can be considered very competitive if they don't find their parents. >>>More
