Inhibitory rate (%) of barnyardgrass in monoculture and rice/BYG mixed-cultures.

Inhibitory rate (IR) was calculated as: IR = (1-treatment/control)×100%. TB – total biointerference, are the IRs of rice on BYG in rice/BYG mixed-cultures; AE – allelopathic effect, are the IRs of BYG monocultured in the residual solutions of rice/BYG mixed-cultures above. RL – root length; PH – plant height; DW – plant dry weight; BYG – barnyardgrass; PI – rice accession PI312777; LE – rice accession Lemont.抑制率（Inhibitory Rate, IR）按下式计算：IR = (1-处理组/对照组)×100%。TB即总生物干扰（total biointerference, TB），为水稻与稗草混培体系中水稻对稗草的抑制率；AE即化感效应（allelopathic effect, AE），为上述水稻/稗草混培体系残留培养液中单培稗草的抑制率。RL为根长（root length, RL），PH为株高（plant height, PH），DW为植株干重（plant dry weight, DW）；BYG指代稗草（barnyardgrass, BYG）；PI指代水稻材料PI312777（rice accession PI312777, PI）；LE指代水稻品种Lemont（rice accession Lemont, LE）。
