What changes do maple trees have throughout the year?

The changing process of maple throughout the year;

In spring, the temperature of maple leaves rises and the tender leaves are light green. In the later stage, maple leaves slowly grow into pinnate or palmately compound leaves. In summer, the leaves will widen and become dark green. When the temperature drops in autumn, the leaves will gradually turn red, which is also the most beautiful moment. Deciduous leaves began to fall in early winter, turned crimson when they fell to the ground, and basically fell out in June+February of 5438.

The flowering period is April-May, and the fruiting period is 9-65438+1October. Branches are brownish red to brown, with small holes, and winter branches are dark brown or gray.

The maple leaves turned red.

Leaves contain a lot of chlorophyll, so the color is green. In autumn, the weather gets cold, the growth rate of trees slows down, and the chlorophyll in leaves is gradually decreasing. Finally, only lutein is left, and the leaves turn yellow. Maple leaf contains a special substance-anthocyanin, which is just the opposite of chlorophyll. As the weather turns cold, the number gradually increases, making the maple leaves turn red.
