Abstract:	The purpose of this study is to investigate allelopathy relationships, for in vitro cultures, between in vitro seedlings of Drosera rotundifolia L. and protocorms of Cymbidium hybridum – plant species belonging to phylogenetically distant families – to establish the tolerability of one to the other in order to organize in vitro floral arrangements, which are increasingly demanded and appreciated worldwide (Halevy, 1999). At the same time, some peculiarities regarding morphological features of in vitro co-culture regime have been analysed. As a result mutual synergistic allelopathy effects which allow in vitro association when cultivated on original MS62 medium of Drosera rotundifolia L. and Cymbidium hybridum species, particularly after a 30 days period of conditioning have been identified. These “aesthetic fireworks” maintain viability and robustness for at least 3 months, representing a source of germplasm with high efficiency in relationship to the monocultures for each of the two species used in this study.
Keywords:	Drosera rotundifolia, Cymbidium hybridum, allelopathy, in vitro, plant biotechnology.
