Apricot (Prunus armeniaca L.) is one of the most important export crops in Palestine and Palestine is the leading fresh and dried apricot producer all over the world.We analyzed the mean annual temperature and precipitation using data from tenth weathers stations from the Palestine Meteorological Department, recorded in the period from 1993-2008 (15 years), with the same years plant production (rainfed) from the Palestinian Central Bureau of Statistics (PCBS). Statistical tests included a bioclimatic analysis of Palestinian meteorological stations for the period previous by using bioclimatic classification of the Earth of Rivas Martinez Salvador, with regard to simple continentality index, compensated thermicity index, annual ombrothermic index, water deficit and soil water reserve. In concluded, when we applied a principal component analysis (PCA), observed that the Ramallah, Salfit, Nablus, Hebron, Bethlehem and Jerusalem areas were affected by the factors simple thermicity index, precipitation, and soil water reserve, excepted Hebron, Bethlehem and Jerusalem were affected by bioclimate factor as annual ombrothermic index, with a proportion of the variance explained by axes 1 (44.55 %) and Jenin and Tubas areas were affected by the bioclimate factors as an annual ombrothermic index. We indicated that in the inframediterranean to mesomediterranean environments, the optimum for the production of apricot is achieved with value of annual ombrothermic index more than 2.5, simple continentality index value between 14-22, compensated thermicity index value between 250-450, the temperature between 20-25°C, with annual rainfall between 300-900 millimeters, and with the dry to humid of ombrotype.
