Some plants are now being commercially propagated using __________ techniques that involve the production of new plants from tissue culture.

Micropropagation is a method of plant propagation that involves growing new plants from small pieces of plant tissue in a controlled environment, typically in vitro, or outside the organism in an artificial nutrient solution. This technique allows for the rapid multiplication of plants while maintaining genetic uniformity.

Micropropagation is particularly advantageous for producing disease-free plants, ensuring that the new plants are identical to the parent plant, which is crucial in agricultural and horticultural practices. This method is often used for species that are difficult to propagate by traditional means, offering a way to regenerate plants quickly and efficiently.

In contrast, cloning generally refers to producing genetically identical copies of an organism, but it may not specifically involve tissue culture techniques. Seedling production typically relates to growing plants from seeds, which is a different propagation method. Hybridization involves the crossbreeding of different plant species or varieties to produce new hybrids and does not rely on the use of tissue culture methods.
