In this article:

The seasonal course of chloride, sodium and potassium accumulation in leaves and berries of several varieties of scions were studied in relation to rootstock effects.

Vines on rootstocks generally contained less chloride, but more potassium than did own-rooted vines.

Cabernet Sauvignon differed from other scions in that vines on Harmony accumulated more sodium than own rooted vines.

High levels of chloride, sodium and potassium were retained by petioles and laminae at abscission.

Possible consequences of rootstock induced changes in the ionic composition of leaves and berries are discussed.
