  1. Each treatment comprised five replicates and average of three for internodes. Values are the means ± standard deviation. Same lower cases represent non-significant difference and different lower cases (a–d) in the same row represent statistically significant differences among the groups according to Tukey HSD Test (p < 0.05).
