| Abstract/Contents: | "Fine fescues are generally considered acid tolerant compared to other cool season turfgrass. However, there is a lack of knowledge on aluminum tolerance of fine fescues at both the species and cultivar level. The objective of this study was to identify the cultivars of fine fescues with superior ability to tolerate Al. Those cultivars which tolerate Al will serve as genetic material for breeding more acid tolerant fine fescue cultivars. A total of 58 cultivars of fine fescues belonging to five species or sub-species (hard fescue: 14 cultivars, Chewings fescue: 25 cultivars, strong creeping red fescue: 15 cultivars, slender creeping red fescue: 2 cultivars, and sheep fescue: 2 cultivars) were selected from the 1993 National Fineleaf Fescue Test and screened under greenhouse conditions using solution culture, sand culture, and acid Tatum soil. An Al concentration of 640 μM and a pH 4.0 were used in solution screening and sand screening. The acid Tatum soil had 80% exchangeable Al and a pH of 4.4. The grasses were seeded and grown for four weeks before harvesting. Relative growth was evaluated for Al tolerance by measuring relative root length, shoot length, root weight, and shoot weight. Differences in Al tolerance were identified at both the species and cultivar level based on relative growth. Hard fescue and Chewing Fescue were more Al tolerant than strong creeping red fescue, slender creeping red fescue and sheep fescue. Among 58 cultivars, 'WX3-FF54' Chewings fescue, 'Discovery' hard fescue, 'Tiffany Chewings fescue, 'Nordic' hard fescue, and 'Ecostar' hard fescue were the most Al tolerant. Within species, significant differences were found among cultivars of Chewings fescue, strong creeping red fescue, slender creeping red fescue, and sheep fescue; whereas no cultivar difference was observed in hard fescue. A relationship was found between endophyte infection and Al tolerance. Fine fescues with endophyte infection generally exhibited greater Al tolerance at both the species and cultivar levels. The results indicate that fine fescues vary in Al tolerance and there is potential to improve Al tolerance with breeding and to refine management recommendations regarding soil pH." |
