Acclimatization of micropropagated plants to ex vitro conditions

The special conditions during in vitro culture result in the formation of p lantlets of abnormal morphology: anatomy and physiology, After ex vitro tra nsfer, these plantlets might easily be impaired by sudden changes in enviro nmental conditions, and so need a period of acclimatization to correct the abnormalities. This review is focused upon contemporary information on the changes in leaf structure, water relations and photosynthesis during acclim atization of plantlets to ex vitro conditions. It also describes some ways of improving plant survival and for the speeding up of acclimatization.
