Temperature is a key climatic factor in determining production and oil quality. Olive is sensitive to low temperatures in terms of frost damage, but requires winter chilling for breaking dormancy of floral buds formed in the previous growing season. As a general rules, the geographical growing area for olive is found where temperatures are not less than -8 , although in some cases mature trees can survive -12 to 118 with adequate winter acclimation. Reproductive structures, buds, inflorescences, and fruit are very sensitive to frost and fruit can be damaged even at -1.7.
