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.
