Abstract
Wear stress is unavoidable for sports turf and lawn, which could crush the leaves, stems and affect root growth negatively by soil compaction. Silicon (Si) fertilizer can strengthen the cell wall, which could be beneficial to the enhancement of turfgrass wear tolerance. The objective of this study was to identify the effect of Si application (0, 25, 50, 100 g m -2 ) on wear resistance of Kentucky bluegrass. The application of 100 g m -2 Si on Kentucky bluegrass could lead to silicon deposition in leaf, thickened stratum corneum, and increased the sclerenchyma number and coverage. The content of cellulose and acid detergent lignin (ADL) increased significantly under 50 g m -2 and 100 g m -2 applications. After wear treatment, the significant improvements for turf quality were found under 50 g m -2 and 100 g m -2 , compared to no silicon control. The content of H 2 O 2 reached a peak at 2 h of wear treatment and enzyme activity of SOD, POD and CAT also increased at first and then dropped under wear treatment. Moreover, high concentration of silicon fertilizer can reduce the electronic leakage (EL) and malondialdehyde (MDA) content. The turf quality was much better in density and color under 50 g m -2 and 100 g m -2 applications. The result showed that a high concentration of silicon fertilizer can protect the membrane system and decrease membrane lipid peroxidation via reinforcing the anatomical structure and increasing the cell wall components.
