Abstract
Studies were undertaken to investigate the response of vegetative growth and root system of two grape-varieties to water stress.
Rooted cuttings of the seeded Romi-Red variety and the seedless Banaty variety Vitis vinifera L were grown in undrained containers.
Watering were controlled by weighing.
There were four treatments to induce the desired water stress, expressed as percentages of available water at 12.5 %, 25%, 50 % and 100 % as control.
The results showed that reduction of available water to 50 % did not affect the growth of shoots or roots significantly.
On the other hand reduction in available water up to 25% or 12.5% had resulted in a decrease of growth of shoots, soft wood, old wood, roots and whole-plant as well as a decrease of leaves number in both varieties.

On the other hand reduction in available water up to 25% or 12.5% had resulted in a decrease of growth of shoots, soft wood, old wood, roots and whole-plant as well as a decrease of leaves number in both varieties.
The response of Banaty variety to low available water percentages was greater than of Romi Red variety.
Thus it may be concluded that Banaty variety was more sensitive to high water stress than Romi Red variety.
