Inhibition of browning problem during micropropagation of Sideritis trojana bornm., an endemic medicinal herb of Turkey

Micropropagation is used increasingly for ex situ conservation of endangered endemic plants and this in vitro technique provides mass propagation of medicinal plants. However during this process, stages of micropropagation are limited by serious problems. One of these problems is the explant browning which is related to the oxidation of phenolic compounds. In this research, several different methods have been used to eliminate the browning problem in tissue culture.
