Potted Sultana vines (Vitis vinifera L. cv. Sultana) on own-roots or grafted onto Ramsey, Harmony, Schwarzmann or 1613 rootstocks were irrigated with solutions containing 1, 10, 20, 40 or 60 mM caused growth to decline by 47% in vines with free-draining rootzones and by 61% in vines with waterlogged rootzones. Under saline conditions, the use of chloride excluding rootstock reduced leaf chloride concentration by 60% in vines with free-draining rootzones but by only 18% in vines with waterlogged rootzones. Waterlogging decreased the root chloride concentration in all rootstocks. The leaf K concentration was reduced by waterlogging at irrigation salinities less than 20 mM NaCl and increased by waterlogging at higher salinities. Waterlogging altered the relative effects of rootstock on leaf K.
