Silicon Application Increases Drought Tolerance of Kentucky Bluegrass by Improving Plant Water Relations and Morphophysiological Functions
Figure 2
Influence of silicon application on (a) stomatal conductance, (b) IWUE, (c) root/shoot ratio, (d) turf quality, (e) leaf blade length, and (f) leaf blade width 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. From = 0–20 days: drought stress period, after 20 days: recovery stage.
