ABSTRACT

Drought is a stress factor that cause of limitation life activities and effects the vegetal
production. Plants are the most important source that feeding necessity of the human
population who increase rapidly. Drought stress, heat stress and heat shock, low heat
and freezing, salinity and oxygen deficiency are the main stress factors that lead to plant
growing. Because of these stress types, the biological mass and yield of plant usually
decreases under of genetic potential at the end of growing season. Drought is occasions
to many of metabolic, mechanical and oxidative changes. These changes related to;
level and period of stress, interactions with other stress types, plant genotype, stage of
growing and active on plants for adapting to limited environmental conditions as many
physiological, biochemical and molecular effects.
