| Abstract/Contents: | "Accumulation of excessive organic matter in form of a thatch and/or mat layer can cause several problems in turfgrass management systems. A previous greenhouse study on creeping bentgrass (Agrostis stolonifera L.) demonstrated that direct application of laccase solution every 2 wk reduced the rate of accumulation of organic matter and hence buildup of the thatch layer. A 2-yr field study was conducted on an ultra-dwarf bermudagrass [Cynodon dactylon (L.) Pers. X C. transvaalensis Burtt Davy, TifEagle] research green, and zoysiagrass (Zoysia japonica Steud., Meyer) maintained as a home lawn to observe the influence of laccase enzyme applications on thatch development. Laccase solution was applied biweekly at the activity levels of 0 (control) and 2.1 units cm-2. Response to laccase enzyme applications by both the turfgrass species was recorded by measuring thatch layer physical and chemical properties after 6 mo of treatment applications within each year. A significant 18 to 22% and 21 to 30% reduction in thatch layer thickness was observed for bermudagrass and zoysiagrass, respectively. Organic matter content (0-2.5 cm) decreased by 23 to 24% while saturated hydraulic conductivity increased by 19 to 30% for bermudagrass in both years. Acid-soluble and -insoluble lignin was reduced in both turfgrass species after laccase treatments. Results indicate that bi-weekly application of laccase on bermudagrass and zoysiagrass has positive impact on thatch management." |
