Figure 4.
Ψl (A), gs (B), and the percentage of affected leaves (C) as a function of days from first detection of embolism in treatment (red) and control (blue) plants. Affected leaves account for yellow, necrotic, or shed leaves. Plants were dehydrated until embolism was detected (day 0) and then irrigated daily for another 20 d. The open symbols (in A and B) or dots (in C) represent six replicate plants (each with a different symbol). The thick lines represent the averages for each treatment (n = 6). The response times of each replicate before irrigation/embolism (negative values) are scaled to the average number of days between the initiation of dehydration and the embolism appearance (7.16 d; see “Materials and Methods”), whereas positive values are actual days.
