C.  aVine and berry response of Merlot (Vitis vinifera L.) to differential water stress.h[electronic resource]  c2006  aMerlot vines were drip-irrigated with 100, 70, or 35% of estimated crop evapotranspiration (ETc) or 35% ETc until veraison followed by 70% ETc until harvest. Midday leaf water potential (Ψ) differed among irrigation regimes and ranged from -0.9 to -1.7 MPa, with a 0.3 to 0.5 MPa difference between 35 and 100% ETc. Decline in shoot growth, berry size, cluster weight, yield, trunk growth, cluster number, and berry titratable acidity corresponded with a decline in Ψ. Increasing irrigation from 35 to 70% ETc at veraison consumed 30% less water producing similar yield and quality as the 70% ETc treatment.  aGrapes  aIrrigation  aEvapotranspiração  aIrrigação  aUva  aVitis Vinifera  aEstresse hídrico  tAmerican Journal of Enology Viticulture, Davisgv. 57, n. 4, p. 514-518, 2006.
