Figure 8. Increase in fresh weight of Paulownia plants in vitro as affected by sucrose concentrations and supporting materials on day 30. In the treatment legends, S and F at the left denote the present or absence of sucrose, respectively. A, G, F, S and V at the right denote agar, Gelrite, Florialite, sand and vermiculite medium, respectively. Different letters on each column show a significant difference at the 5% level by Duncan's multiple range test.
