Chimera in Plants – White or Yellow Patches on Leaves
Sometimes in crops like tomato, watermelon, or other vegetables, farmers observe half-white or yellowish patches on leaves, often along the veins. This condition is commonly mistaken for a disease, but in reality, it is a natural phenomenon.
Why does Chimera occur?
Chimera occurs due to a natural genetic mutation. In this condition, some plant cells are unable to produce chlorophyll, the green pigment responsible for photosynthesis. As a result, certain areas of the leaf appear white or pale yellow.
Is it a disease?
This is not caused by any disease, virus, or fungus. It does not spread to other plants and generally does not harm plant growth or yield.
Why do white parts burn?
The white portions of the leaf are sensitive to sunlight and may develop brown burn-like spots.
What should farmers do?
There is no need for any chemical spraying to manage chimera. If required, farmers can remove the affected leaves or branches.
