FACTORS INFLUENCING VITRIFICATION OF CARNATION AND CONIFERS
A similar result was obtained when we made analyses of macro and microelements in the plants using atomic absorption spectrophotometer. The results showed that if we applied different amounts of microelements from the disposable nutrients the smaller part was taken from the macroelements and the greater part from the microelements. The vitrification rate was reduced on medium containing MS macro with Heller microelements, simultaneously the multiplication rate increased. In this experiment the test plant was gerbera. Vitrification of shoots frequently occured during embryo culture of some conifers. Applying high cytokinin level or activated charcoal increased vitrification, it was also affected by different choice of culture media.
