Plant specific emission pattern of biogenic volatile organic compounds (BVOCs) from common plant species of Central India

In this study, we examined 49 representative plant species of the Achanakmar-Amarkantak Biosphere Reserve (AABR) forest of Central India for emission of a number of biogenic volatile organic compounds (BVOCs). The BVOCs emissions from seven plant species are reported here for the first time. The emission rates of different plant species were ranged from negligible to 80.6 +/- 0.82 (gg(-1)h(-1)). Forty-seven plant species were found to emit isoprene and monoterpenes (23 high emitters, 12 moderate emitters, and 12 low emitters). Dalbergia sissoo showed the maximum total average volatile organic compound (TAVOC) emission rates (80.6gg(-1)h(-1)). The percentage composition of monoterpenes was also varied across different plant species. Alpha-pinene (-pinene) was found as the most dominant monoterpene with about 41.40% of the total monoterpene emission. The highest emission range of -pinene (7.8gg(-1)h(-1)) was observed in Murraya koenigii. Carene was emitted only from two species (i.e., Mangifera indica and Terminalia tomentosa). When the emission rates of present study were compared to previous studies, there were considerable differences even for the same species. The study also reports the emission of BVOCs from Shorea robusta for the first time which is the most dominant plant species of the AABR (covering 60% of the total forest area).
