  1. Water-deficit stress at three osmotic stresses (control, − 0.4, and − 0.8 MPa). Plants inoculated (AM +) or not inoculated (AM−) with the arbuscular mycorrhiza fungus F. mosseae, two German chamomile varieties (Bodgold (Bod) and Soroksari (Sor)). Means followed by common letter are not significantly different at the level of 5% (LSD test)
