Asymmetric inter-specific competition between invasive Phytolacca americana and its native congener

Interspecific competition determines the invasive capability of alien plants. Phytolacca americana, one most destructive plants in China, was first discovered and recorded China 1935. Since its arrival, rapid expansion species has driven out a native congener, acinosa. In this study, we assessed competitive interaction P. americana acinosa pot experiment at Yunnan University. Our results indicate that severely inhibits growth reproduction Furthermore, demonstrated superior resistance against both insect predation bacterial infection. We suggest improved tolerance herbivory potentional pathogen damage may be cornerstone to success americana.
