I am recently working with onion root for TEM. In the mature zone, both
epidermal and hypodermal (exodermal) cells develop suberized walls which
are impermeable to water and solutes and therefore fixation and resin
infiltration are very difficult. If you have exprience with this
problem, I'd like to appreciate hearing from you.
