Heavy metal induced resistance to herbivore of invasive plant: implications from inter- and intraspecific comparisons

ABSTRACT:

Introduction

Heavy metals can affect the content of secondary metabolites in plants, which are one of the important defenses of plants against herbivores. However, studies on the effects of heavy metals on secondary metabolites of invasive plants are scarce. Phytolacca americana is an invasive plant in China, which can hyperaccumulate the heavy metal Mn.

Methods

This study used two Mn treatments (control and treatment group) and four species from Phytolacca (including the native and introduced populations of P. americana, its native and exotic congeners in China) to investigate the impact of heavy metal Mn on the invasive ability of P. americana.

Results

The results show that heavy metal Mn can enhance the inhibitory effect of the introduced populations of P. ame
