Abstract/Contents:"Branching behavior of Zoysia japonica, with and without disconnection at four levels of soil nitrogen content were examined within one growing season. With the decrease of overall soil N levels in the habitats, the branching intensity in terms of number, length and mass tended to decrease, in intact treatments, and increase in disconnection treatments. The average masses of roots at multiple-nodes with branches were usually greater than on those without branches. Root masses at multiple-nodes in the poor soil tended to be greater than corresponding ones in the rich soils. The proportion of branches produced from the rich soil patches were dominant over those from the poor soil patches for all clones. Among whole branches, A-branches were dominant over B-branches in terms of various morphological parameters. The results of ANOVA revealed that the branching behaviors of Z. japonica clones in response to overall soil nitrogen levels and the treatments of intact and disconnection were very different. Branches contributed greatly to the total dry matter production of Z. japonica clones and A-branches constituted a major proportion of this production."
