| Abstract/Contents: | "Rapid leaf elongation in tall fescue is accompanied by a reduction in tillering. Leaf and tiller development were monitored in three populations differing in leaf elongation rate and tiller production. Young tillers were removed from treatment plants shortly after they appeared above the ligule of their subtending leaf. Tiller removal had little effect on leaf elongation rate but reduced the duration of elongation. Duration of elongation in the expanding leaf controlled the rate of new leaf and tiller appearance. Cessation of elongation was associated with the appearance of the tiller found at the same node as the expanding leaf as well as initiation of elongation in the leaf located two nodes above. Increased tiller density had no effect on the triggering of leaf elongation but did delay new tiller appearance. A clear synchrony of initiation events was displayed suggesting a high level of communication among leaves and tillers on a plant." |
