Abstract
Variation of monoterpene, sesquiterpene, neutral diterpene, and fatty and resin acid composition was determined in adult needles of two chemotypes of Pinus pinaster Ait., sampled in two different seasons: summer and winter. Throughout the year, the terpenic and fatty acid composition of adult needles of P. pinaster showed a seasonal variation, both at individual and at global level. These seasonal variations in distribution pattern were not produced in the same way in the needles of the two chemotypes studied. Therefore, we consider that secondary metabolism compounds do not present the same sensitivity to environmental conditions, and genetically different trees have different responses to these environmental conditions.
