Experiments with Siratro were conducted at Samford, outh east Queensland to study the effectsof previous cutting and defoliation treatments on regrowth. In the first experiment, swards of Siratro were cut at 7.5cm above ground level every 4 weeks, every 8 weeks or cut once at 16 weeks during spring and summer. Rregrowth of all teatments over ten weeks was measured after varying (by leaf removal) the stubble leaf area index (LAI) of the plots cut every four weeks. Pattern of regrowth yield was similar for all treatments with a pronounced lag phase after cutting.Regrowth yield after 10 weeks differed between treatments and was linerly related (P<0.01) to residual LAI in the stubble at the start of regrowth. In the absence of stubble leaves, plots previously cut at 16 weeks or at 8 weeks yielded marginally more than those cut every 4 weeks. There were no marked treatment differences in goss root morphology other than a two fold increase in stolon rooting for the 16 week treatment. Nitrogen content of the roots (mean 1.38 per cent) was unaffected by treatment, but the per cent hot water soluble sugars were lower for the 16 week defolation treatment than for the 8 week and the 4 week treatments. |
