The germination of Chinese cabbage should be the bolting phenomenon of Chinese cabbage.

Chinese cabbage is a biennial crop, and the cabbage balls we usually eat belong to the nutrition of Chinese cabbage. Chinese cabbage continues to grow after long sunshine at low temperature, completing the whole life process of flower bud differentiation, bolting, flowering and fruiting, which means that bolting of Chinese cabbage is not a pathological phenomenon, but a necessary stage in the growth cycle of Chinese cabbage.

Cabbages stored in winter are usually sown in early autumn and harvested in the middle of 1 1 month, when the cabbage has completed its vegetative growth.

Chinese cabbage bought by consumers is used to being stored outdoors. After a long period of low temperature, flower buds will appear on the Chinese cabbage. If the cabbage is put indoors again or the temperature rises, it will slowly bolting.

There is no obvious difference in nutritional value and taste between bolting Chinese cabbage and ordinary Chinese cabbage. Some areas in the south even have eating habits of bolting Chinese cabbage (Chinese cabbage), but it is a special variety used to produce Chinese cabbage.

However, it should be noted that if bolting occurs during the vegetative growth period (before heading), it will inevitably consume the nutrition of Chinese cabbage balls and affect the quality of Chinese cabbage, so don't choose bolting Chinese cabbage when buying.

Li Yan, a professor of botany at Northwest A&F University, said:

"Vegetable germination is a very common phenomenon, especially in summer. Our common cabbages and radishes germinate easily. It depends on the nutrients stored in roots and leaves, and will germinate under suitable conditions. After the vegetables germinate, the nutritional value will be reduced and the water will be lost. Therefore, vegetables such as cabbage, garlic and radish can also be eaten, but the nutritional value is not as good as fresh vegetables. "

Moreover, some vegetables are poisonous and inedible when sprouting, such as potatoes, sweet potatoes and peanuts. Professor Li said: "When potatoes germinate, they will produce a toxin called Solanum nigrum, which is harmful to health. If there is less germination, the germinated part can be eaten. If the potato has turned green in a large area, it can't be eaten. "

Extended data:

Chinese cabbage (scientific name: Chinese cabbage? (Lour。 )Rupr。 ) is a biennial herb in Cruciferae.

The height can reach 60 cm, the whole plant is hairless, with many basal leaves, large leaves, obovate oblong to broadly obovate, blunt top, wrinkled edges, white flat petiole, bright yellow flowers, oblong or ovoid-lanceolate sepals, erect, light green to yellow; Petals obovate, pedicels spreading or ascending, seeds spherical and brown. It blooms in May and bears fruit in June.

Originated in North China, it is widely cultivated in various places.

Chinese cabbage is the main vegetable in winter and spring in Northeast China and North China. Raw food, fried, salted, sauce stains can be; Leaves falling off the outer layer can be used as feed.

Chinese cabbage has many varieties, rich nutrition and certain medicinal value.

Cabbage likes cold climate, the average temperature is 18-20℃, and it grows best in sunny conditions. It can safely overwinter at -2~-3℃. The temperature above 25℃ is weak, and it is easy to suffer from virus disease. Only a few heat-resistant varieties can be cultivated in summer.

Germinated seeds and green plants of Chinese cabbage complete vernalization within a certain number of days below 65438 05℃, with flower bud differentiation starting from seedling tip and leaf differentiation stopping. Bolting and flowering under long sunshine and high temperature. But the requirements of different varieties for long sunshine are obviously different.
