Abstract/Contents:"Seeding of creeping bentgrass (Agrostis stolonifera) in spring months is a common practice on golf course greens with significant winter injury. However, significant temperature fluctuations including freezing events may impact the rate of establishment. The objectives of the study were to examine the effects of freezing events on creeping bentgrass at the seedling stage, and to assess any differences in freezing recovery traits among 12 different creeping bentgrass cultivars. Seed of each cultivar were established in pots containing a USGA soil mix and maintained at 15┬░C. Three weeks after emergence, the seedlings were exposed to a freezing event (-5┬░C for 8 h), followed by recovery at 15┬░C at two light intensities (100 and 500 ┬Ámol m-2 s-1). Pre- and post-freezing measurements included a visual estimate of green cover and leaf injury, quantification of membrane lipid peroxidation using malondialdehyde content, and changes in chlorophyll fluorescence parameters including photochemical efficiency (PE), maximum photochemical quantum yield (QY), and non-photochemical quenching (NPQ). Creeping bentgrass cultivars exhibited approximately 30% higher damage following freezing when exposed to higher light intensity. The higher light intensity exposure following freezing was also associated with lower PE and QY, lower antioxidant content, and higher lipid peroxidation. Among the tested cultivars, Piranha and Declaration exhibited the lowest levels of injury, whereas Memorial and Barracuda displayed the highest levels of post-freezing injury."
