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 Fe 3+ and Cu 2+ 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.
