| Abstract/Contents: | "Understanding how environmental factors affect the longevity of roots is essential if root mortality linked nutrient cycling processes within ecosystems are to be understood, and the impact of natural and anthropogenic climate change properly evaluated. In this study the longevity of roots at the two geographically and climatically distinct sites were compared to identify the scale of change that can occure due to environmental differences. Minirhizotron tubes were inserted into swards sown with the same variety of Lolium perenne and Trifolium repens at sites in the UK and Italy. Roots were viewed using a video camera and digitized images of roots generated at intervals. From these images the life history of individual roots was determined and compared. There were few differences in patterns of longevity between different species at the same site. Major differences however, were observed between roots of the same species at different sites. For example, 73% of Trifolium repens roots failed to survive for 21 d in Italy compared to only 29% at the UK site. Similarly, over 84% of Lolium perenne roots failed to survive for more than 21 d in Italy compared to 38% in the UK. These data suggest that environmental factors can have a huge impact on root longevity." |
