Osmotic potential ([[PSI].sub.[pi]]) was determined with a calibrated vapor pressure osmometer (Model C-52, Wescor Inc., Logan, UT) and read with a psychrometer microvoltmeter. Leaf relative water content (LRWC) was determined gravimetrically on a leaf disc and calculated from the relationship: [([W.sub.fresh] - [W.sub.dry])/([W.sub.turgid] - [W.sub.dry])] x 100, where [W.sub.fresh] was the weight of fresh sample, [W.sub.dry] was the oven dry weight, and [W.sub.turgid] was the turgid weight after floating the sample in water for 4 h (Jensen, 1989).
