Abstract

The testing results indicated that 15% Paclobtrazol wettable powder significantly decreased the plant height and fresh weight of rice, the higher the dosage was, the more obvious the decreasing degree was. Moreover, Paclobtrazol at high dosage (9.0kg/hm~2) would cause the malformation of rice leaves. But 50% Quinclorac wettable powder at the dosage of 0.375~1.50kg/hm~2 had no significant effects on plant height and fresh weight of rice. After applying mixed 15% Paclobtrazol and 50% Quinclorac, the decrease in plant height and fresh weight of rice was caused only by the former.
