2.4. Statistical analysis
Each treatment was conducted with three replicates, and the results are presented as mean±SE (standard
error of the mean). Germination percentage, root length and number of roots were analyzed using HOVTEST
to evaluate variance homogeneity and normality. In case of non-homogeneity, data were transformed using
angular transformation before further statistical analysis [23, 24]. The data was analyzed using the SPSS
GLM procedure in SPSS to determine single or interaction effects of factors. Whenever a significant
interaction was determined, the level of one factor was compared to each level of the other factor by all pairwise
multiple comparison procedures (Turkey’s test), unless mentioned otherwise. All data are presented as
mean±SE. A significance level of α = 0.05 was used in all analyses.
