Olive oils extracted from pulp and seed of two cvs. (Frantoio and Coratina) derived from rooted cuttings were examined after growth to production in Italian localities between 40 deg and 46 deg North. Results have shown that the oil content of pulp decreases in colder climates, whereas percentage content of oleic acid increases parallel to a decrease of linoleic acid, apparently in contrast to Ivanov's principle. On the contrary the oil content of seed shows no climatic dependence. At higher latitudes the acid composition shows an increase of linoleic acid content and a decrease of oleic acid, in agreement with Ivanov's principle. Percentage sterolic composition of olive pulp - and seed - oils shows no certain relation to climate.
