| Abstract: | The chelating agents, EDDHA, its iron salt, EDTA, and salicylic acid enhance bud formation in Bartramidula bartramioides (Griff.) Wijk & Marg. Salicylic acid elicits optimal response at 10–4 M , whereas the other substances do so at 10–7 M . Increased concentration of ferric citrate and cupric sulphate also stimulate bud induction. The accumulation of Fe3+ and Cu2+ is facilitated by chelators. The endogenous iron content is maximum at 10–7 M EDDHA or EDTA, which is also the concentration optimal for bud induction. |
