Tissue Culture Propagation: The Future of Plant Multiplication

Did you know that there is a way to grow hundreds of identical plants from a single cell? Micropropagation is a revolutionary technique that allows commercial and hobby growers to propagate plants from small samples of plant tissue in a sterile environment, giving them new and unprecedented possibilities. Let us take a look at how this method works and how you can try it at home.

What is propagation through tissue cultures?

Propagation using tissue cultures involves growing plants from small samples of their tissue in a sterile environment. The process begins with an explant, a small piece of plant tissue taken from the mother plant. The explant is placed in a sterile container filled with a gel-based nutrient medium enriched with vitamins and hormones that support plant growth. Once the plant tissues are preserved in this way, they can be divided into hundreds or even thousands of genetically identical clones.

This process is remarkable for its flexibility. The tissue can remain in a sterile environment for a long time until it is activated by specific hormones to develop roots and shoots, which allows long-term archiving of plant genes. Thanks to sterilisation, the tissue sample can be freed from all pathogens, pests and diseases, and in some cases it may be the only way to rid plants of viral diseases such as hop latent viroid (HpLVd).

How do tissue cultures differ from seeds and cuttings?

Growers traditionally rely on seeds or cuttings for plant propagation. These methods are effective, but they have their limitations:

Seeds: The main disadvantage of growing from seeds is the unpredictable results. Seeds do not always have 100% germination, and some plants may suffer from unwanted genetic mutations. In the case of growing dioecious plant species, unwanted male plants can be a problem. Last but not least, crop uniformity is not guaranteed with seeds, and plants from the same parents will show greater or smaller differences in appearance and growth.

Cuttings: Propagation by cuttings is faster, and cloned plants are identical to the mother plant. The disadvantage of cuttings is the relatively high risk of transferring diseases and pests from the parent plant to the clones. Cloning also requires consistent maintenance of mother plants, which is demanding in terms of both labour and space.

Micropropagation of tissue cultures solves most of the problems associated with growing plants from seeds or cuttings. The sterile environment eliminates pests and diseases, and in some cases even genetic disorders. The plants are genetically identical, and tissue cultures can be stored in small containers that take up significantly less space and require less care than mother plants. Tissue cultures allow growers to produce thousands of plants from a single explant in a short time, which is invaluable especially for commercial large-scale growers. Last but not least, micropropagation can be used to “reset” the plant’s biological clock and rejuvenate old or rare specimens. This method can also be used to germinate seeds that are decades old and restore lost genetic material.
