*2.7. Experimental Design and Statistical Analysis*

The experimental design was completely randomized and consisted of six treatments (three light sources × two banana varieties), with five replications per treatment. Each replication consisted of 3 baby food flasks containing 1 in vitro plantlet per flask for a total of 90 experimental units. Data were collected and submitted to analysis of variance (ANOVA) using the R statistical analysis program, with means compared by LSD (Least Significant Difference) test at the 5% level of significance.
