From: ABA-mediated responses to water deficit separate grapevine genotypes by their genetic background
Physiological responses of nine grapevine genotypes to water-deficit. Shoot water potential (a) and transpiration (b) 1 day (black bars) and 4 days (grey bars) after withholding irrigation. For A and B, bars represent mean ± standard deviation (n = 3) and asterisks show significant water-deficit effect (Kruskall Wallis, p-value < 0.05). For B, values among genotypes with the same letter are not statistical different (day 1 and day 4 analysed separately with an ANOVA on ranks, p-value < 0.05). The relationship between the changes in transpiration and shoot water potential (c), key to symbols: RGM, filled circle; 101-14Mgt, open circle; SO4, inversed filled triangle; 161-49C, open triangle; 41B, filled square; 110R, open square; 140Ru, filled diamond; Syrah, open diamond; Grenache, filled triangle. The dashed line shows the global linear regression for all nine genotypes, solid lines show those genotypes with a significantly different relationship from the global linear regression (Fischer-Snedecor test; p < 0.05)
