Emergence and Survival of Cool Season Grasses under Drouth Stress1

Abstract

Abstract

Alternating moist and dry periods were used to evaluate 19 grasses, including six genera and several cultivars of some, in a growth chamber experiment. Two types of drouth tolerance were demonstrated: drouth tolerance of seedlings and presence of dormant or quiescent seeds that can survive alternate dry and moist periods. A grass significantly higher in the first type of drouth resistance was ‘Sawki’ Russian wildrye (Elymus junceus Fisch.). Pennlate orchardgrass (Dactylis glomerata L.) showed a very high degree of drouth tolerance of the second type.
