nonacosan/picea

This is the first report of population variability of the contents of n-alkanes and nonacosan-10-ol in the needle epicuticular waxes of Serbian spruce (Picea omorika). The hexane extracts of needle samples originated from three natural populations in Serbia (Vranjak, Zmajevački potok, and Mileševka

The n-alkane composition and the nonacosan-10-ol content in the needle cuticular waxes of Serbian spruce (Picea omorika), Bosnian pine (Pinus heldreichii), and Macedonian pine (Pinus peuce) were compared. The amount of nonacosan-10-ol in the needle waxes of P. omorika was higher than those in P.

Epicuticular wax structures and epicuticular wax composition were studied in needles of Picea abies (L.) Karst. plants after a long-term fumigation experiment. SEM observations showed aggregated as well as undamaged waxes without any relation to treatments. The chemical wax analysis revealed clone

Epicuticular wax tubules were reconstituted in vitro by recrystallizing nonacosan-10-ol from the soluble cuticular lipids of Picea pungens Engelm. on a glass support. Fumigation of these preparations for 100 h with dry O3 (1.8 %), SO2 (100%) or for 1500 h with NO2 (0.1 %) did not change their
