AB  - Sodium chloride was supplied to rooted cuttings of Vitis vinifera cv Cabernet Sauvignon grown in a porous growth medium at concentrations of 0, 20, 50 and 75 mM. Shoot and leaf growth and berry set and development were reduced by NaCl, the severity of the effects depending on both NaCl concentration and the age of the plants receiving the treatment. Shoots were not affected by 20 mM NaCl supplied 10 days after flowering, but 50 and 75 mM NaCl caused severe stunting of shoots and 75 mM NaCl had a marked effect on berry growth and development. When NaCl was supplied to vines 10 days before flowering, 20, 50 and 75 mM NaCl inhibited shoot growth and reduced berry size and sugar content. Although NaCl caused a decrease in the rate of growth of both leaves and berries, no changes in invertase or pectin methylesterase activities were found in these organs from plants supplied with NaCl.
