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. Keywords- Temperature, Heat stress, Mapping, Fars Province
