The headspace analyses of pollen, whole living female and male flowers, and staminoids have beenperformed on Laurus nobilis L. (Lauraceae) from Italy to determine whether there are differences inthe volatiles emitted in order to give a contribution to the roles of the different flower parts in thepollination ecology of dioecious plants. Also, the essential oils obtained from male and female plantshave been studied to evaluate a possible correlation between the spontaneously emitted volatilesand the constituents stored in the glandular tissues. Furthermore, the headspace sampling techniquehas been improved, with respect to previously employed methods, by means of solid-phasemicroextraction (SPME).Keywords: Laurus nobilis; essential oil; pollen and flower volatiles; male and female plants
