Abstract
Dehydration of slices of rhizomes led to an increase of iridal esters (IE) with a concomitant drop of free iridals (FI), as well as phosphol ipids (PL), in the drought-resistant species, Iris germanica. By contr ast, in the wetland species, I. pseudacorus, lysis of IE is observed, while the PL content remains around the control level. The origin of f atty acids incorporated into IF and the possible role of iridals again st stress injury within Iris species are discussed.
