Studies have shown positive growth effects of silicon, such as increased disease resistance, but the effect of Si on many ornamental and greenhouse crop species has not been extensively studied. A step in determining its potential benefits is the documentation of Si uptake and localization in the plant. Using scanning electron microscopy and energy dispersive X-ray analysis, the authors detected Si deposits on the leaf margins. This report is the first documentation of Si uptake or accumulation in any species of the Balsaminaceae family.
