Why do trees shed leaves?

With the onset of autumn, the trees undergo many different changes. Meanwhile, leaf shedding is a major feature of trees. The trees undergo a number of unique changes with the onset of the winter season. Trees that were active become inactive. As a result of that pose a plethora of eye-catching color patterns. It varies in different colors such as purple, yellow, and red.

No matter how much the trees change color, even large trees lose their leaves, none of these actions are artificial. This is because of the hypersensitivity of the trees.

Changes in the color and pH of a tree depend on the health of the tree. After spring and summer, the chlorophyll, a chemical pigment, is deposited on the cells of its leaves. This gives the leaves a green color and acts as an energy source for the plant. Photosynthesis is important for trees to absorb the energy they need from the sun. It also provides water, carbon dioxide, and chlorophyll to a tree. That is why green is the predominant part of the life cycle of a tree. In addition, there are pigments of carotenes, anthocyanin, and xanthophyll. The tree is green during the active period, but when it becomes inactive, other colors begin to shine. With the beginning of winter, the production of green color ceases and other colors appear. As the pH level of the plant rises, the pigment darkens. This is similar to the color found on ripe cherry and red maple.

Adaptation of trees to Winter

Many changes in the plant occur with a drop in temperature. The green color of the trees is reduced due to the inability of the trees to get the required energy. Therefore, the health level of the tree is reduced and the nutritional process is impaired. At the same time, the color green of the trees erased and reflects the other colors stored by the green color. In this process, the tree uses its energy to produce red instead of green. The red color is produced naturally to block sunlight. This is also the most common color in autumn.

The anthocyanin and chlorophyll are very helpful in changing these colors. Anthocyanin and chlorophyll produce brown and anthocyanin and carotenoid produce orange. These components combine to form a red color. These include orange, purple and yellow. It creates colorful patterns that delight viewers. No matter how many investigations have been done, the cause has not been found yet. During this tropical period, deciduous trees are abundant in the northern part of the earth and slightly less in the southern part. The color of the trees in these areas is green. Also in some areas, these color changes are ignored and produce magical color-changing leaves. In temperate climates, the red color is very low, but in England, it is 70% red during this time of year.

Common deciduous trees in the Northern Hemisphere include several species of ash, aspen, beech, birch, cherry, elm, hickory, hornbeam, maple, oak, poplar, and willow. In tropical and subtropical regions, deciduous trees include several species of acacia, baobab, roble, ceiba, chaca, and guanacaste.

Sayings about leaf fall

“The leaf starts healthy and you will look more flamboyant in the fall,” said Allen Smith.
“It really depends on the tree and the ecosystem. We have wonderful foliage here, but we do not have forest cover. Every tree has a chemical that is produced. It helps the tree to benefit and survive.” – Sam Rhodea
All of these pigments produce the chemical constituents that the plant needs. Carotene and xanthophyll help the tree produce the energy it needs. This energy is used to delay the leaf shedding of trees with the onset of the season.
