Defoliation is a natural phenomenon. Generally in autumn, most deciduous plants and trees begin to lose their leaves. The leaves become yellow and curled, falling from the trees and fluttering in the wind. It means that after late autumn, winter is coming.
Northern my country is located in the north temperate zone. In autumn, due to lower temperatures and less rain, the root absorption of plants is reduced, and the water and inorganic salts received by the plants are greatly reduced, so they cannot carry out normal operations. Physiological activities such as photosynthesis, respiration and transpiration. If you continue to retain the leaves, a large amount of water will evaporate, threatening the survival of the plant. After cold and drought, new leaves will grow.
There are two situations of falling leaves:
One: Whenever drought or cold season comes, all the leaves die and fall off, leaving only the branches, making it a deciduous tree, such as a peach. Another type: after new leaves appear in spring and summer, the old leaves gradually fall off, and the whole tree becomes evergreen all year round, such as camphor.
Causes of fallen leaves:
1. Internal causes: After a certain period of physiological activities in the leaves, a large number of metabolic products, such as minerals, accumulate in the cells, causing physiological function decline and death (chlorophyll destroy).
2. External factors: The weather becomes colder, the soil temperature decreases, the rainfall decreases, and the water provided by the root system decreases. Falling leaves can reduce transpiration and water consumption, which is beneficial to the survival of plants in cold and dry seasons.
