*2.7. Statistical Analysis*

The experiments in this study were repeated thrice using a completely randomized design (CRD) with 20 explants per treatment, and the results were expressed as mean value and standard error (SE). One-way analysis of variance (ANOVA, San Francisco, CA, USA) with Tukey's honestly significant difference test (Tukey's HSD) analysis was performed for comparisons of significant differences between treatments at a *p*-value of less than 0.05. The data were processed and analyzed using IBM SPSS version 24 (SPSS Inc., Chicago, IL, USA) and the graphs were created using the Microsoft Excel by Microsoft for Windows for Mac.
