IRRIGATION & IRRIGATION MANAGEMENT

The Australian dried grape industry strives for innovation, ensuring its processes are efficient, sustainable and fair.

Improving grapevine water use efficiency

In this article:

Research has found it is possible, through slow partial drying of the rootzone, to separate the biochemical responses to water stress from the physical effects of reduced water availability.

Initially experiments were at producing a system for control of canopy vigour, however it became apparent the technique also has the potential to influence water use efficiency and fruit quality.

We have shown it possible to bring about substantial changes in patterns of growth and development by applying basic knowledge of physiological events which control responses to water stress.

The Partial Rootzone Drying concept allows us to switch on defense mechanisms intended to improve water use efficiency during drought, without risking the deleterious effects of reduced water potential.
