Emergence and Survival of Cool Season Grasses under Drouth Stress1
- Glen M. Wood and
- Paul A. Kingsbury2
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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
