This study was conducted to determine the growth characteristics, and the effect of plant growth regulators on the sprouting and growth of purple nutsedge(Cyperus rotundus L.) in order to establish effective control system in lawn ground. The flowering of purple nutsedge was initiated 30days after transplanting regardless of the transplanting time. Low temperature less than 10 degrees after flowering was required for tuber formation, showing that the tuberization was related to air temperature. Shoot number and dry weight of underground portion of purple nutsedge was slighth affected by plant growth regulators such as benzylamino purine, abscisic acid, brassinosteroid and jasmonate.
