Table 2. Root formation of intact Pinus radiata seedlings after 6 weeks from injection with A. rhizogenes strains. Mean values ± SE from all treatments of a parameter were compared and those means denoted by the different letter are significantly different (P<0.05) using Duncan's multiple range test following ANOVA (p-values for % survival, % rooting and No. of rooting/cutting were 0.531, 0.01 and 0.006, respectively). Data of percentages were converted by arcsin transformation prior to ANOVA. Control = intact seedlings injected with YM medium only. |
