| Abstract: | After a period of exposure to wind in a wind tunnel, two aspectsof the resulting mechanical damage in Festuca arundinacea Schreb.var. S170 were examined. These were the frequency of occurrenceof transverse fold lines and the microscopic nature of leafabrasion marks. Transverse fold lines were found to be of morefrequent occurrence in wind-exposed plants. A stereoscan electronmicroscope was used to show the severe damage to the leaf surfacethat can result from leaves rubbing over each other. Some possibleconsequences of such damage are discussed. |
