Table 3. Effect of
two A. rhizogenes strains on survival and root formation of de-rooted
seedlings of Pinus radiate. 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 roots/cutting were 0.676, 0.014 and 0.230, respectively).
Data of percentages were converted by arcsin transformation prior to
ANOVA. Control = de-rooted seedlings without inoculation with the agrobacterium.

(after six weeks from bacterial inoculation). |
