The response of seven Welsh provenances of Molinia caerulea to wind was assessed by measuring leaf growth and tillering. Leaf growth was usually depressed whilst tillering tended to increase. On the basis of the results, an example of a wind-resistant and wind-susceptible provenance was chosen for further study. The wind-susceptible provenance displayed the lowest water potentials in the wind treatment, but this did not arise as a result of it having a more easily damaged leaf surface than the resistant provenance. The essential difference between the two provenances appears to be in the hydraulic pathway from the soil to the leaf surface.
