| Abstract/Contents: | "Three experiments were conducted under controlled environment conditions at Rutgers University to investigate critical soil temperatures influencing creeping bentgrass growth. The results include: Growth and physiological activities of both roots and shoots of creeping bentgrass declined when plants were exposed to elevated rootzone temperatures at or above 23C for extended periods of time. The rootzone temperature that caused the decline varied with plant parameters and stress duration. The decline in net photosysnthesis [photosynthesis], root production and activities occcured at lower rootzone temperatures and earlier during the treatment compared to turf quality. Therefore, effective management practices, such as syringing and inserting fans, should be taken when physiological signs of heat injury occur and when soil temperature reaches the minimum detrimental levels to prevent declines in visual turf quality during summer months. Lowering soil temperature by 3 C from 35 C was effective in improving shoot and root growth of creeping bentgrass when air temperature was maintained at high level (35 C). The effectiveness of soil cooling for turf growth increased with the duration of cooling and the amount that the soil temperature was reduced. Soil cooling at night was more effective than soil cooling during the daytime for maintaining quality of creeping bentgrass exposed to high air temperature." |
