| Abstract: | The average relative growth rate (RGR) and net assimilation rate (NAR) were decreased with increasing of the stubble height . Plant growth retardant treatments did significantly decrease average RGR of perennial ryegrass while NAR did not changed. |

| Keywords: | plant growth retardant perennial ryegrass average relative growth rate net assimilation rate |
