Shoots of five horticultural crops were cultured in the following systems, 1) the “Culture Pack” -Rockwool (CP-RW) system, a prototype of film culture system, 2) its practical model (PCP-RW system), and 3) a conventional culture system (BOS·AGAR). The aim is to investigate the efficiency of film culture systems on the in vitro production of plantlets. Regardless of the culture medium used and plant species examined in this study, increased growth of plantlets was obtained in both film culture systems as compared to those in the conventional system. This suggests that PCP?RW system is more efficient and has a greater practical value in micro-propagation of many crops than the conventional culture system (BOS·AGAR).
