文摘

North American common reed (Phragmites australis subsp. americanus) is a plant of interest for wetland restoration and management, but propagation under controlled conditions has been hindered by chlorosis and slow growth. In a greenhouse experiment, addition of Fe(II) (reduced iron) alleviated chlorosis and significantly increased biomass, stem height, leaf and root production, chlorophyll B, and fluorescence parameters. Supplementing with Mg(II) (reduced magnesium) did not improve plant health measures and suppressed the stimulatory effect of Fe(II).
