摘要：

In vitro rooted microcuttings of Callistemon sp. were transplanted into pots and placed for hardening in a fog system in the greenhouse, with or without application of 50% shading. The transplanted microplants remained in these conditions for 1 or 2 weeks and then were moved to greenhouse conditions. At the end of the 3(rd) week after transplantation the survival rate was measured. Also, at the end of the 3(rd) and 4(th) week, measurements regarding plantlet height and number of new leaves were taken. Reduced light over microplants; (application of shading) in the fog system increased the transplanting losses. The lowest transplanting losses (3%) were noticed when the microplants were kept without shading in the fog system for 2 weeks and then were transferred to the greenhouse. The height of the young plantlets was not influenced by the light regime, while the number of new leaves was higher for those that were maintained in fog without shading for 1 week.
