Abstract : Temperature is one of the most important parameters affecting plant growth and yield production. Increasing
world population and the growing demand for food products in the world, has provided the context for emergence of stress
to plants. In general, adverse conditions that do not cause immediate death and permanent, or temporary happen in a place is
called stress. Tolerance of plants in relation to each of the meteorological parameters is limited and any abnormalities in
these parameters can have a significant direct or indirect effects on agricultural production affect. In the present study, the
critical threshold of heat stress for wheat cultivation in Fars Province was evaluated and the equations for each critical
threshold is presented. Finally mapping of the entire province of heat stress has been done. According to the requirements of
the average for wheat, thermal thresholds of 30, 35 and 40 ° C as the maximum temperature and 20 ° C as the minimum
temperature has been considered. The evaluation results showed that the southern part of Fars Province consists mainly
Larestan, Mohr and Khonj and northwestern parts including Kazeroon and Mamasani are more susceptible to heat stress and
Meanwhile larestan and mamasani more than other areas suffer from stress. In most cases, periods of heat stress coincide
during germination and flowering of wheat culture in Fars Province. Maps provided by climatological analysis helps to
agriculture managers to estimate Probability of favorable or unfavorable atmospheric events in later stages of crop
development with high accuracy. These predictions can be used in practical farming and long-term planning.
