Effects of vegetation season and needles? position in spruce canopy on emissions of volatile organic compounds
Original language description
The main objective of this study was to investigate seasonal changes and vertical distribution in emissions of biogenic volatile organic compounds (BVOCs) within a Norway spruce canopy profile. Emissions were measured on current-year needles from the upper and lower canopy in early July and late August. Our results show that total BVOC emissions under standardized conditions (light intensity 1,000 ?mol m?2 s?1, temperature 30°C) are higher in July than they are in August. BVOC emissions from upper canopy needles were approximately 3 times higher than were those from lower canopy needles. This difference was observed in July but not in August. The monoterpenes ?-pinene, camphene, and terpinolene showed the most significant differences between emissionsfrom upper and lower canopy needles.
