Autumn is the quietest and softest season of the year. Different from the bright spring, the freshness of summer and the icy cold of winter, autumn gives a feeling of softness and tranquility. Maple leaves are red, and the sun is not as hot as summer. Very warm to people. The autumn sun brings warmth to people, and everything is covered with a furry brilliance under the autumn sun. Autumn is beautiful, autumn is yellow, red, and autumn is the color of maple leaves.
The leaves of maple trees are generally called maple leaves. The shape of the maple leaf is about the size of the palm and is palm-shaped. Maple leaves generally have five lobes, and some varieties are three-lobed, about 13 cm long. Generally speaking, maple leaves are green in spring and summer, fall leaves in winter, and slowly turn red in autumn. Why do maple leaves turn red in the fall?
This is because all leaves contain green chlorophyll, which trees use to absorb light energy and store it in the form of chemicals with the help of other substances in the leaves. In addition to chlorophyll, many leaves also contain carotene, yellow pigment, red pigment and other pigments. While these pigments do not photosynthesize like chlorophyll, some are sufficient to convert captured light energy into chlorophyll. In spring and summer, chlorophyll in leaves is much richer than other pigments, so leaves appear green because of chlorophyll, and the color of other pigments cannot be seen.
In autumn, the days are shorter, the nights are longer, and the trees are dropping their leaves. Trees no longer produce as much chlorophyll as they do in spring and summer, and existing chlorophyll, like chlorophyll, gradually breaks down before leaves fall. In this way, as the amount of chlorophyll gradually decreases, the colors of other pigments also gradually appear on the leaves, producing colors such as yellow and red.
Among the many red leaf trees in the world, the maple tree is the most attractive. This beautiful tree and its beautiful shape of leaves are much loved. Can be used as a shade tree, street tree or companion tree in gardens. It can be combined with other fall foliage or evergreens to enhance fall beauty.
However, there are many types of maple trees, and not all maple trees will turn red, some will not change color, and some will turn purple or yellow. In general, the most ornamental and representative maple leaf species are Acer with chicken feet, Maple with tea strips, Maple with bloodskin, Maple with light leaves and so on. In fact, we can see their characteristics from their names. For example, the blood-skinned maple is a typical discolored maple leaf. It will become blood-red and very strong; while the light-leaf maple will become bare and only straight. The trunk of the tree, but this is another kind of beauty.
