Özet
Propagation of some commercial plants having difficulty in reproductions by seed or vegetative propagules conventionally is established by in vitro tissue cultures techniques. The techniques such as micropropagation provide fast methods for production of a large number of uniform plantlets in a short time. As compared with conventional propagation methods, different culture techniques have many advantages such as a rapid propagation of valuable genotypes, production of disease-free plants, non-seasonal production during all the year and germplasm conservation. Techniques used to propagate commercially important plants in vitro are relations with axillary branching, adventitious shoot formation and somatic embryogenesis. Most commercial micropropagated plants are derived from axillary shoot formations. Recently bioreactors including liquid culture media have been designed for multiplication of plants because of their advantages of scaling up and automation. Tissue culture techniques used for propagation of many commercial plants have a few limitations such as high cost of production, requirement of high technology and educated staff, somaclonal variation risks on clones during culture, difficulties on development of a protocol for recalcitrant plants etc. In vitro propagated plants under aseptic and highly protected conditions need an acclimation period for ex vitro conditions. Many ornamentals, fruit rootstocks, woody species, industrial, medicinal crops, and also the other plants have been propagated through tissue culture techniques successfully and transferred to ex vitro conditions for many years. The micropropagation industry in Turkey is a growing sector with advantages such as lower labor cost and advanced knowledge of the academicians.
