| Abstract/Contents: | "A stand of Kentucky bluegrass (Poa pratensis L.) consists of a collection of leafy tillers at various stages of development. Tiller morphology over two yr of growth was studied by sampling 3-yr-old dryland fields to determine tiller ages and to test whether burned and non burned fields show different proportions of tiller types. Three classes of tiller were identified and named: (i) small newly emerging non leafy D tillers, (ii) leafy F tillers that grow directly from D tillers, and (iii) leafy C tillers that have persisted for at least a year before flowering. On the basis of measurable floral features, C tillers are larger, more robust, can be induced sooner in the fall, and produce panicles of greater production potential than F tillers. Our results show that bluegrass tillers can be annual or biennial in flowering habit. Dense populations in burned fields produce higher proportions of D tillers in mid-fall than non-burned fields, but similar proportions of C and F tillers throughout the growing season. Fall regrowth may thus influence stand composition over a 2-yr growth cycle. Assessment of tiller density should be a useful tool for grass seed growers when they are designing new management strategies, since annual F and biennial C tillers are found in all of the cultivars examined. Given pressures to avoid open-field burning, alternative methods can be tested by determining change proportions of C to F fillers. Manipulation of the balance between annual and biennial tillers may contribute to improving yield in the absence of open-field burning." |
