Relative neighbor effect (RNE) of each of the two rice accessions and barnyardgrass in rice/BYG mixed-cultures.
A – RNE of BYG in mixed-cultures with PI and with LE. B – RNE of PI and LE in mixed-cultures with BYG. PI – rice accession PI312777; LE – rice accession Lemont. BYG – barnyardgrass. * –significantly different in different treatment groups (P<0.05).

Inhibitory rate (%) of barnyardgrass in monoculture and rice/BYG mixed-cultures.
Figure 2.
Separation of resource competition (RC) and allelopathic effect (AE) in rice/BYG mixed-cultures.
A – Inhibitory rate (IR) of PI on BYG in PI/BYG mixture. B – Inhibitory rate (IR) of LE on BYG in LE/BYG mixture. TB – total biointerference. RC – resource competition. AE – allelopathic effect. TB (total bars) = RC (shaded bars)+AE (open bars). RL – root length; PH – plant height; DW – plant dry weight. PI – rice accession PI312777; LE – rice accession Lemont. BYG – barnyardgrass.
