| Abstract/Contents: | "Cocksfoot (Dactylis glomerata L.), perennial ryegrass (Lolium perenne L.), and Italian ryegrass (Lolium multiflorum Lam.) plants were grown in a glasshouse and in a controlled environment, and soil water deficits were allowed to develop slowly or rapidly. Changes in relative lamina water content (RWC), total lamina water potential (LWP) and osmotic potential (OP) were measured as drought progressed. Osmotic adjustment (corrected to full turgor) was greatest when drought developed slowly. Perennial ryegrass adjusted most, by as much as 0.8 MPa. Cocksfoot, although the most drought tolerant species and most able to retain green leaves, was least able to adjust osmotically and maintain turgor during drought. Problems connected with measuring LWP of very stressed leaves, and with estimating OP at full turgor are described and analysed. The use of the various watering regimes in controlling leaf water status is discussed in relation to the selection of grasses for osmotic adjustment and turgor maintenance during drought." |
