Response of Salvinia cucullata to high NH4+ concentrations at laboratory scales
Growth, morphology, NH4+ uptake and mineral allocation in Salvinia cucullata Roxb. ex Bory grown with different amounts of NH4+ were investigated. Plants of uniform size were grown on full strength Smart and Barko medium with different NH4+ concentrations (0.5, 1, 5, 10 and 15 mM) and incubated in a...
