| Abstract: | Aims
Sorghum halepenseis a perennial invasive weed causing great harm worldwide, including some regions on Hainan island. In this study, we compared the performance between plants from outbreaking (dense stands covering large areas) and those from non-outbreaking (less dense stands covering smaller areas) populations. We also tested the hypothesis that plants with greater intraspecific competitive ability will have a lower stand biomass when grown under high-density conditions. |
