1 Values represent the average shoot formation in three Petri dishes with 10 explants and three replicates.
2 [(Number of embryogenic axes with novo shoots/total of embryogenic axes) x 100]
3 Mean ± SE
Same letters within columns denote statistically equal means with the Tukey Unequal N HSD test (P < 0.05). Treatments that gave the best results of shoot formation are highlighted in bold.
