Stem water potential of the four Vitis species during the recovery experiment. (PDF 63 kb)

Normalized relative quantities (RT-qPCR) for NCED3 and DHN1 in young propagated vines in response to WD. (PDF 79 kb)

Figure S1. Number of significantly altered metabolites under water stress identified using GC-MS (primary metabolites) and LC-MS (secondary metabolites) during the course of the experiment. (PPTX 38 kb)

The effect of water deficit upon the relative metabolic content of five anthocyanidins and their glycosylated, acetylated and coumaroylated moieties within the red cultivars. All metabolites were significant at the Cultivar level except malvidin 3-O-(6-p-coumaroyl)glucoside and petunidin 3-O-(6-acetyl)glucoside. Cultivar and treatment abbreviations for experimental replicates: Cabernet Sauvignon (CS), Merlot (ME) and Pinot Noir (PN), grown under well-watered (W) and water deficit (D) conditions. Error bars represent mean ± SE, n = 6. (PDF 13 kb)

Stem water potential measurements (MPa) for the North and South vineyards. Water potential measurements were averaged across cultivars, Cabernet Sauvignon and Chardonnay in the North and Merlot, Pinot Noir and Semillon in the South. Symbols represent mean ± SE; n = 6 (North) and 9 (South). WW = well watered, WD = water deficit. (PDF 165 kb)

The University of Nevada, Reno’s Experimental Vineyard is located at 39°32’20.14” N by 119°48’22.00” W. Grapevines were grown in two adjacent vineyards under independent irrigation controllers. Red lines designate rows of water-deficit treated vines and blue lines designate well-watered vines. The north vineyard was divided in half (dotted line), with Chardonnay (CD) grown in the upper half and Cabernet Sauvignon (CS) grown in the lower half. The south vineyard was divided into six blocks, each containing four rows, with three blocks allocated to either water-deficit or well-watered treated vines. The block and row locations for Merlot (ME), Pinot Noir (PN), and Semillon (SM) are indicated. The experimental replicate sampling scheme for each technology is depicted. Six experimental replicates for each treatment and cultivar were harvested. (PDF 570 kb)
