英文摘要: Increasing nitrogen (N) deposition is one of the main drivers of global change, while the emission of biogenic volatile organic compounds (BVOCs) from plant in response to elevated N deposition is poorly understood, especially with respect to the response to foliar application of N. In this study, BVOC emissions from two tree species (Pinus massoniana Lamb. and Schima superba Gardn. et Champ.) were determined by dynamic chamber coupled with a proton transfer reaction-time of flight-mass spectrometer. Two N application methods, namely soil application of N (SAN) and foliar application of N (FAN), and three N levels (5.6, 15.6 and 20.6 g N m−2 yr−1) were employed by applying NH4NO3 every week for 1.5 years. The results showed that: (1) oxygenated volatile organic compounds (OVOCs, mainly acetaldehyde, methyl alcohol, ethenone and acetone) and non-methane hydrocarbons (NMHCs, mainly monoterpenes, propyne, 1,3-butadiene and propylene) were the dominant BVOCs for all the treatments, accounting for 32.40–65.72% and 19.21–47.39% of total 100 determined BVOC compounds, respectively; (2) for S. superba seedlings, both SAN and FAN treatments significantly decreased total BVOC emissions (11.83% to 66.23%). However, total BVOCs from P. massoniana significantly increased with N addition for SAN treatment, while no difference were found in the FAN treatment; (3) BVOC emission rates for FAN treatment were significantly lower than those for SAN treatment, indicating that previous studies which simulated N deposition by adding N directly to soil might have imprecisely estimated their effects on plant BVOC emissions. Considering the inconsistent responses of BVOC emissions to different N application methods for different plant species, close attention should be paid on the effects of N deposition or even global change on plant BVOC emissions in the future. © 2019 Elsevier B.V.
