1. The
effects of bacterial strains and IBA on root formation of P. radiata
hypocotyl segments upon culture for 6 weeks. Mean values ± SE
from all six treatments of each of the three parameters (% of survival,
% of rooting and No. of roots/cutting) were compared using Duncan's
multiple range test (a=0.05) following ANOVA at P<0.05 (p-values
were 0.222, 0.016 and 0.003, respectively). Those means that were different
among the different treatments of a parameter are denoted with a different
letter. Data of percentages were converted by arcsin transformation
prior to ANOVA. Control = hypocotyl segments not inoculated. |
