In vitro salinity stress tolerance in Urochloa brizantha cultivars

Colloquium Agrariae, 2021
Urochloa brizantha is the main forage grass to raise cattle in Brazil, but salt stress can reduce yield. Physiological and molecular mechanisms of adaptation to salt stress remain poorly understood in this species. The objective of this work was to evaluate the responses of three cultivars of U. brizantha to in vitro salt stress.
