Simon, J.E. | Reiss-Bubenheim, D. | Joly, R.J. | Charles, D.J.
Mild and moderate plant water stress increased sweet basil leaf essential oil content and altered oil composition. After 21 d of plant water deficit, the oil content of leaves increased from 3.1 to 6.2 microliters per gram leaf dry wt. as xylem water potential decreased from -0.30 to -1.12 MPa. Significant decreases in leaf dry weight and stem dry weight were observed as plant water deficit increased. Only leaf area from plants subjected to a mild water deficit (-0.68 MPa) was not significantly reduced compared to the control, nonstressed ants.
