Iron translocation I. Plant culture, exudate sampling, iron-citrate analysis.

Abstract

Plant culture, exudate sampling, and analytical methods designed to ascertain the form of iron translocated are presented.Restoration of iron to sunflower plants precultured at different Fe levels resulted in exudate iron concentrations ranging from 0.2 to 31 x 10(-5)m. Citrate was from 3 to 89 x 10(-5)m. Iron and citrate were highest in exudates from iron… (More)
