The Effects of Shaking on the Growth and Water Relations of Festuca arundinacea Schreb

The extension growth of Festuca arundinacea was reduced by shaking,and the leaves formed during shaking were thinner and narrowerthan the controls. The response to shaking was modified by thenutritional status of the plant — shaken plants took upmore phosphorus from a phosphorus deficient soil than the controlsand this advantage seemed to offset the influence of shaking. Shaken plants displayed a higher stomatal conductance and alower water potential than the controls, though it was consideredthat the effect of shaking could not be attributed entirelyto differences in water potential.
