Abnormal depression: After entering winter, the temperature begins to drop, the growth of plants almost stops, and most plants enter the dormant period. As people have concluded based on experience, winter is the season when all things sleep. In winter, the temperature becomes very low and the cold wind blows. The leaves of the plants turn yellow and fall off, leaving only bare branches. Compared with other seasons, it will appear very lack of vitality and vitality, and extremely depressed. Because most plants have poor cold resistance, they may even freeze to death if they are outdoors, but this is considered a relatively normal phenomenon.

Improved cold resistance: After entering winter, plants enter depth During the sleep period, respiration weakens,reduces the consumption of nutrients, and the metabolic intensity of the entire plant also weakens A lot,helps in the accumulation of nutrients such as sugar,can enhance stress resistance sex. In addition, the concentration of plant cell fluid will also increase, which can lower the freezing point and play a role in self-protection. During the cold resistance exercise year after year, the amino acid content of plants gradually increases, and the content of proline also increases significantly, which can play an anti-freeze role and play a certain role in the plants themselves adapting to adversity.

Autumn is the season of falling leaves. After entering autumn, the leaves of some perennial plants will turn yellow and gradually wither and fall. Annual plants may enter the end of their lives and slowly wither and die. Most plants will lose their leaves in autumn because after entering autumn, the temperature drops, the light weakens, and there is less rain. The water and nutrients that the roots of the plants can absorb are greatly reduced, which is not conducive to their normal photosynthesis and transpiration. In this case, if you continue to retain the leaves, the plant's water will be consumed faster, which is not conducive to survival. Therefore, the most obvious change in plants after entering autumn is the withering and falling of leaves.
