From: ABA-mediated responses to water deficit separate grapevine genotypes by their genetic background

Fig. 4

Relationship between ABA concentration changes and plant water status. Plots of the changes from day 1 to day 4 after withholding irrigation in abscisic acid (ABA) concentration in the shoot sap and transpiration (a) and shoot water potential (b) for nine grapevine genotypes (key to symbols as shown for Fig. 1c). Each point represents difference between means at day 4 and at day 1 (n = 3). The black lines show the global linear regression for all nine genotypes, dashed black lines show the 95 % interval of confidences for the regressions
