Screening methods for waterlogging tolerance in Urochloa grasses

Waterlogging is a stress experienced by the roots and reflected upon the shoot. As such, screening procedures that includes root traits that are known to confer adaptation to waterlogging may greatly improve selection for waterlogging tolerance in Urochloa grasses.

Screening procedures should be performed under adequate nutrient levels to avoid confusion of low growth rates and waterlogging tolerance.

Conatiner size have an effect upon waterlogging tolerance. A long cylinder system is recommended to screen rooting depth (an proxy for root aeration efficiency in Urochloa grasses) under waterlogged soil conditions.
