What are the spots on the leaves of plants?

Colorful flowers and golden fruits have always been the best products for people to watch, but now, colorful foliage plants have begun to appear. Some of them are famous for their unique leaf shapes, some for their beautiful and elegant appearance, and some for their colorful spots. Among them, those foliage plants that look like flowers are the most attractive.

There are many kinds of foliage plants, such as white jade evergreen, which breaks the common style of evergreen in the past. The white jade-like color appears in the center of the leaf, making it look elegant and delicate. There is also ivy, whose leaves are yellow and roots are white, like a string of jadeite, hanging down, dazzling colorful orchids on one of its leaves, mixed with pink ivory, lavender and other pigments. The audience was surprised by the Brazilian iron with a silver edge and a gold heart in Phnom Penh, where there were clusters of leaves that looked like a huge flower. There is a golden ribbon embedded in the center of the green leaves, which is very elegant and moving. There are also rubber banyan azalea colored leaf stalks and fleshy cactus, and many colorful "new partners" have appeared one after another, making the family of foliage plants more colorful!

When you see the white green leaves of the ivy in Phnom Penh hanging in front of the window swaying in the breeze, and the green leaves of the cauliflower taro on the console table glow with little red dot, you may think, how can there be such charming spots on the leaves of these plants? This is called "leaf spot disease" in plant ecology, and there are many kinds. There is a famous foliage plant "alternifolia", which grows in tropical areas. The leaf spots on its polymorphic leaves are yellow spots, orange spots, pink spots and brown spots, which are dotted in the green leaves and are strip-shaped and dot-shaped. Botanists call this point "star spot"; Some foliage plants have dark red lines on the green leaves to outline the clear outline of the veins, which are called "dots"; Some foliage plants with golden stripes on their leaves are called "spots"

The leaves of plants are originally green or red, so why do some plants grow such strange spots on their leaves? According to the research of scientists, this is because the pigment in leaf cells plays the role of a magician. When plants grow, if the chlorophyll production mechanism in leaves is blocked or the cells produce gene mutation, anthocyanin lutein carotene will be put on the stage in a certain part of the leaves, and colorful wonders will appear on the leaves, which can also be realized by physical and chemical methods. For example, X-ray irradiation can cause mutation of plant leaves and induce leaf spot disease.

Among the rich and colorful plant resources in China, there are many precious foliage plants, and this beautiful development wish is waiting for you-young friend, waiting for you to decorate our life more colorful.
