摘要：

In vitro culture of eight Ficus benjamina clones was initiated from shoot tips four times from January to June 1988. Shoot formation and growth in vitro were followed during eight subsequent subcultures, whereafter the developed shoot clusters were rooted in vitro. Significant differences among clones in proliferation rate and time to emergence of first root in vitro were observed. A superior clone 'Cleo', previously selected for fast growth as a potted plant, also proved to have the highest proliferation rate and the shortest time until emergence of first root in vitro. The proliferation rate was nearly stabilized after five subcultures. A negative correlation between proliferation rate and time to emergence of first root in vitro was found.
