  • Figure 2
    Figure 2

    Maximum trunk shrinkage (MDS) for Tempranillo and Cabernet Sauvignon in 2004 (A), 2005 (B), and 2006 (C). Data are the mean of six plants in 2004 and eight plants in 2005 and 2006. Bars indicate standard deviation.

    Stem water potential (Ψs) for treatments T1 and T2 of Tempranillo and Cabernet Sauvignon in 2004. Bars indicate standard deviation.

  • Figure 7
    Figure 7

    Maximum trunk shrinkage (MDS) for Tempranillo and Cabernet Sauvignon for treatments T1 (A), T2 (B), and T3 (C) in 2004. Data are the mean of two plants. Bars indicate standard deviation.

  • Figure 8
    Figure 8

    Variations in trunk diameter fluctuation (MDS) and vapor pressure deficit (VPD) during selected days in 2006 for. Tempranillo and Cabernet Sauvignon before (A) and around veraison (B).

  • Figure 9
    Figure 9

    Relationships between maximum daily shrinkage (MDS) and mean daily vapor pressure deficit (VPD) for Tempranillo and Cabernet Sauvignon for the whole season (A) and at preveraison (B) for 2004, 2005, and 2006.
