partitioning, <strong>and</strong> transpiration water use efficiency (TWUE) were determined at the end of the<br />
experiment. Interspecific competitive indices (competitive ratio (CR), aggressivity (A) <strong>and</strong> relative<br />
yield total (RYT)) were calculated from the biomass dry weight data for shoots, roots <strong>and</strong> total<br />
biomass. The response of the species to the presence of each other at different proportion was<br />
compared <strong>and</strong> evaluated at the three levels of soil moisture. Results showed that water stress<br />
decreased biomass production of both species in monoculture <strong>and</strong> mixture. B. ischaemum was more<br />
sensitive to water deficit in biomass production. The growth of L. davurica was restrained in their<br />
mixtures under each water treatment. B. ischaemum had significantly (P
