| Abstract/Contents: | "A field experiment was conducted to determine the changes that occurred during the year following establishment in depth and growth of roots under Agrostis stolonifera cvs. Penncross and SR1020. Replicated plots of each cultivar were established in September 1995 following standard procedure for a golf green. Management of the plots (i.e. mowing, irrigating, fertilising and pest control) followed commercial green keeping practices. Every 2-4 weeks, a soil core to a depth of 30 cm was removed from each plot using a split-tube sampler. The core was stratified into 2 cm depths, the roots were extracted by washing, and root length, width and dry weight were measured. Rooting depth, root length and root dry weight of the whole core sample increased with time after establishment. The rates of increase in these attributes of growth were greatest during the first 10 weeks and by 54 weeks, growth appeared to be approaching a "plateau". In contrast, root width declined with time, although as with length and weight, the change was greatest intially and declined towards the end of the experiment. Differences between cultivars were seldom consistent over the whole experiment, except in root weight where cv Penncross was up to 30% heavier than SR1020 at some harvests. A future paper will detail the temporal and spatial variation in root growth within each stratum of the soil profile. However, the results presentd here make some progress towards the development of an empirical model of root growth of Agrostis stolonifera." |
