During autumn, the amount of sunlight decreases, which weakens the photosynthesis process of leaves. As a result, trees are unable to produce enough chlorophyll, which is essential for their growth.
To compensate, they break down the chlorophyll in their leaves, causing them to turn yellow and fall off. This is why most trees shed their leaves in autumn, and they turn golden-yellow before falling with the wind.
These trees are often tall and used as street trees, such as the sycamore, which is known as the king of street trees due to its high ornamental value during autumn. Let's take a look at the trees that have golden leaves.
<b>1. Populus Euphratica</b>
Populus euphratica is a plant of the family Salicaceae and the genus Populus. It is a deciduous medium-sized natural tree, up to 1.5 meters in diameter. The leaves of Populus euphratica are broad and fragrant, and the leaves begin to turn yellow in autumn. It is resistant to drought and waterlogging. which makes it one of the rare tree species in nature.
<b>2. Metasequoia</b>
Metasequoia is a deciduous tree with opposite branchlets that droop down. Its leaves are linear, measuring 1 to 1.7 cm in length. Metasequoia is highly adaptable and grows faster, thriving in a humid environment. The color of Metasequoia leaves varies according to the season. In spring and summer, when life is vigorous, the leaves are emerald green. During autumn, the leaves turn yellow and become golden, making it the best season for viewing.
<b>3. Poplar Tree</b>
Some trees, such as Poplars, have leaves that turn yellow during autumn. Poplars are known for their tenacious vitality, straight trunks, and relatively smooth bark. They have many roots and can be firmly planted in the soil. Planting poplars outdoors can help prevent wind and sand and absorb exhaust gases.
<b>4. Ginkgo</b>
Yellow ginkgo leaves are indispensable in autumn. The evolution of ginkgo began hundreds of millions of years ago. It is not surprising that it is a "living fossil" on Earth.
Furthermore, the tree's growth rate is exceptionally sluggish, requiring approximately 40 years before it becomes laden with fruits. Its leaves have thin petioles, and the leaves are shaped like a fan. The leaves in spring and summer are light green, and the leaves in autumn turn golden yellow and fall with the wind.
<b>5. Cherry Tree</b>
Cherry trees bloom and grow leaves every spring. The flowers are white or pink and the leaves are green. But when autumn comes, the nutrients that can be absorbed by the roots of cherry blossom trees decrease, causing the leaves to turn yellow and dry, and eventually fall off, leaving only the bare trunk.
