Abstract

A natural, tidal-flat clone of Zoysia sinica was studied to compare ramet growth properties in central area with in peripheral area. In new stolon and rhizome, internode length, weight, shoot height and weight, and spike production were monitored on July 25, 2004. The weight/height rate of shoot between stolon and rhizome, the shoot/stolon (or rhizome) rate in weight between central and peripheral area were not different. However, other properties differed in stolon from rhizome or between central and peripheral area significantly differed: 1. The rhizome in central area had a larger node number, shorter internode length, higher shoot height, larger shoot biomass, and higher rate of non-shoot nodes than that in peripheral area. 2. The stolon in central area had a smaller node number, shorter internode length, and smaller biomass than that in peripheral area. 3. In the same area, the rhizome had a larger node number (except for central area), shorter internode, higher shoot height, larger shoot biomass, higher rate of non-shoot node, and higher rate of node having over two shoots than the stolon. No relationship could be found between shoot size and spike production in shoot on vertical rhizome (lower node of old shoot).
