Gilg,a traditional medicinal plant in China,was studied in its natural distribution range.The reproductive tactics of A.sinensis were studied in detail by employing various tests dealing with fruit set and also seed dispersal.Dynamic headspace extraction followed by GC-MS analysis was also performed in order to reveal the composition of floral scent.The results showed that noctuids and pyralids are the most effective pollinators of pollinator-dependent A.sinensis.The main compounds of the floral scent were(E,E)-α-Farnesene(61.9 ± 3.2%),trans-Ocimene(16.6 ± 1.2%),and Benzyl salicylate(4.6 ± 1.1%).The results obtained from seed dispersal experiments indicate that hornets are effective seed dispersers and they may play an important role in long-distance seed dispersal of A.sinensis.Based on our findings,we recommend several protection methods for this threatened agarwood plant in China.展开更多
