“…Some related research indicated that 2, 4-D played a more important role in callus formation from leaf and stem explants compared to BA (Satyavani, Ramanathan, & Gurudeeban, 2011).But in this experiment, Calli were successfully generated in all treatments regardless of 2, 4-D concentration and different types of explants (Table 1).These results showed that leaf and stem explants were suitable for callus induction. Similar results were reported in callus induction of Corydalis saxicola and Orthosiphon stamineus, in which it were described that callus could be induced successfully from leaf, petiole, stem (Cheng, Yu, Hu, Chen, & Sun, 2006).…”
