Figure 5. Application of strain 22A to R. japonicum.

Figure 5

A and B, growth-promotion experiment of R. japonicum in hydroponic culture. A, branch number per plant during cultivation. Circle, 22A-applied sample; triangle, methanol medium; and square, control (water). Data are presented as mean ± SEM (four replicates of n = 100). B, apical growth at the end of cultivation. Data are presented as mean ± SEM (four replicates of n = 100). C, gametophyte growth of R. japonicum in a field experiment using different support materials. White bar, average size of the plants before the experiment (bar, standard deviation only to left side); and black bar, increase in size after the experiment (bar, standard deviation only to right side). Statistical significance of the difference between control and 22A-treated samples is shown as * (p<0.05) and **(p<0.01) (Student's t-test, n = 50).
