| Abstract/Contents: | "Wear damage is a major concern in sports turf management. The objective of this study was to evaluate genetic variations in several morphological and anatomical parameters of perennial ryegrass (Lolium perenne L.) exposed to wear stress. Eight cultivars differing in wear tolerance based on a field experiment were examined for wear tolerance. Mature plants of all eight cultivars collected from field plots were grown in plastic pots filled with soil and subjected to wear stress for 21 d in a greenhouse. Wear stress was imposed using a wear simulator made of rubber paddles mounted on an axle. The wear simulator was operated at approximately 160 rpm and applied approximately 10 seconds of wear on each pot during each pass of wear. During 21 d of wear treatment, 132 passes were applied to each pot. Overall turf performance was evaluated by measuring shoot density, green leaf biomass (NVDI) and leaf area index (LAI) using a multispectral radiometer. Following 21 d of wear treatment, 'Citation Fore', 'Cabo', 'Cathedral II', 'Pacesetter', 'Manhattan 4' and 'Charger II' had the highest shoot density, NVDI and LAI, followed by 'Manhattan', while 'Linn' had the lowest values, suggesting perennial ryegrass cultivars varied in performance under wear. The top-performing cultivars that maintained higher shoot density, green leaf biomass, and leaf area index generally had finer leaves with short compact cells, and lower total cell wall content and lignin content than the poor-performing cultivars. Our results suggest that selecting for perennial ryegrass cultivars with high shoot density, flexible cell walls, and compactly arranged cells may improve plant performance under wear stress." |
