Abstract Crop performance and yield are the results of
genotypic expression as modulated by continuous interaction
with the environment. Among the environmental factors,
water is one of the most important, which limits the
crop production on a global basis. Water resources in the
world are steadily diminishing, and in many areas, including
Poland, more frequent periods of drought are observed.
There are many problems that are specifically
related to water scarcity: an extremely dynamic nature of
plant water status, relationship to the severity of the effects
of water, time stress during ontogeny of plants, and the
interaction of water stress with other environmental variables.
The paper presents a review of recent literature on
the effect of the grasses to drought stress at the level of
physiological processes and the possibility of yielding. A
better understanding of how long-term growth and yield
are affected by water stress should aid in improving irrigation
efficiency and practices, in modifying plants for
more efficient water use, and in developing effective dryland
agriculture.
