The aim of this research was to prepare a map of the spatial distribution of aril paleness, soil texture, climate, rain gauge centers and salinity of irrigation water and soil of 19 pomegranate orchards in Saveh region to investigate the relationship between these factors with the occurrence and severity of paleness. The results showed that in all orchards, paleness occurred with different severity during two years; and the severity of the complication was higher in the second year. Also, 68% of the orchards had unsuitable irrigation water and salty soil and in the second year, a higher average temperature was recorded compared to the first year. In addition, 60% of the orchards were in the range of soils with sandy-loam texture, all the gardens were in the dry climate and in the area of the rain center. Generally, the geographical location of the orchards probably did not affect the occurrence of aril paleness; but the factors of temperature, salinity of irrigation water and soil and soil texture play a role in the occurrence/severity of complication. Temperature was directly identified as the main factor in the occurrence and severity of this complication. The salinity of irrigation water and soil together with temperature or each alone has a significant role in the incidence and severity of paleness. Regarding the soil texture, it seems that the role of this factor in the severity of the complication can be considered during the salinity of the soil or irrigation water.
