| Abstract/Contents: | "Poa annua L. is a highly successful weed within golf greens in many parts of the world, and is the predominant species in the sward of most British golf greens. Globally, there are many ecotypes that exist, ranging from true annual forms through to long-lived perennials. However, to date no study has recorded the occurrence of different ecotypes in UK golf putting greens. In this study, Poa plants were isolated from the greens of four different golf courses, representative of the soil types and ages of course which can be found in the UK. We chose three old, soil-based courses and one recently-constructed course with USGA greens. Plants were grown in isolation and the morphological characteristics, flowering events and mortality of these individuals were recorded over a six month period. We looked for associations between life history characteristics and course type, and differences in flowering data between courses. Hierarchical cluster analysis was used in an attempt to group individual plants into potential ecotypes by course type. The majority of plants isolated from old courses were perennial in nature, while those present in the USGA course tended to show more annual characteristics. The older courses included a variety of different soil types, therefore the difference in ecotypes from these and the USGA course was probably due to age of the courses, rather than variation in soil properties. The data suggest that golf greens are invaded initially by annual ecotypes that, due to the production of large amounts of seed, are adapted for rapid colonisation. However, one Poa becomes established within sward, selection pressures rapidly favour the more hardy and prostrate perennial ecotypes that are more suited to survival within the golf course green ecosystem. It appears that perennial ecotypes may enter the sward by interbreeding with the already established annual populations in the older courses were more stable, being dominated by ecotypes with perennial characteristics." |
