Which method is most commonly used in micropropagation?

The most commonly used method in micropropagation is tissue culture. This technique involves the cultivation of plant cells, tissues, or organs under controlled environmental conditions on a nutrient culture medium. Tissue culture allows for the rapid multiplication of plants, as it can produce a large number of genetically identical plants in a relatively short period.

One of the primary advantages of tissue culture is that it enables the propagation of plants that are difficult to grow from seeds or cuttings, including those that may not produce viable seeds or have long germination periods. Moreover, this method is essential for the propagation of plants that are genetically superior, ensuring that desirable traits are preserved through clonal propagation.

By employing tissue culture, plant growers can generate disease-free plants and maintain the genetic fidelity of the desired traits, making it a valuable technique in agriculture, horticulture, and conservation efforts.
