Silicon Application Increases Drought Tolerance of Kentucky Bluegrass by Improving Plant Water Relations and Morphophysiological Functions

Figure 1

Influence of silicon application on (a) photosynthesis, (b) transpiration rate, (c) leaf relative water content, (d) soil water content, (e) green color of leaf, and (f) relative growth rate of Kentucky bluegrass under drought stress. ns: nonsignificant; DAT: days after treatment; Ww: well watered; Ds: drought stress; Si-0, Si-200, Si-400, and Si-800 means Si application at 0, 200, 400, and 800 mg L−1, respectively. 0–20 DAT: drought stress period; 20–34 DAT: recovery stage.
