Chemically induced variegation in plants refers to a phenomenon in which changes in the color or patterning of plant leaves, stems, or flowers are caused by the application of chemical agents. This can be done for a variety of reasons, including to produce plants with attractive or unusual coloring for decorative purposes, to create plants with enhanced resistance to pests or diseases, or to study the genetic basis of pigmentation in plants.

Chemically induced variegation can be achieved using a number of different chemicals, including hormones, growth regulators, and pigmentation inhibitors. These chemicals can be applied to plants either directly or indirectly, through the use of media or plant growth conditions that affect the production or distribution of pigments within the plant.

One example of chemically induced variegation is the use of auxin, a plant hormone that regulates cell division and elongation, to create plants with unusual leaf patterns. By applying auxin to certain areas of a plant, it is possible to create patterns of variegation such as stripes or rings.

Chemically induced variegation is a useful tool in plant breeding and horticulture, as it allows for the creation of plants with unique and visually appealing characteristics. However, it is important to use these chemicals carefully, as they can have unintended effects on plant growth and development.
