Effects of Sulfur Dioxide and Ambient Ozone on Concord Grapevine Growth and Productivity

Year: 1985

Type: article

Abstract: Three separate experiments were conducted in a mature Vitis labruscana Bailey ‘Concord’ vineyard in New York to determine the response of grapevines to daily, season-long sulfur dioxide (SO 2 ) exposure, or to intermittent SO 2 exposure simulating emissions from a 1700 MW coal-fired power plant. There was little SO 2 -induced necrosis on grape foliage from daily or power plant SO 2 . However, both treatments in ambient air increased susceptibility of leaves to oxidant stipple injury due to ambient ozone (O 3 ). Daily SO 2 increased leaf chlorosis. Power plant SO 2 had no effect on vine growth, yield, or shoot maturation. Daily SO 2 reduced soluble solids, growth, yield, and shoot maturation of grapevines. Damage to grapevines from SO 2 seemed to be independent of SO 2 induced leaf necrosis. SO 2 reduced foliage tolerance to O 3 injury in grapevines already stressed by ambient O 3 .
