Abstract:
Field experiments were conducted in 2003 to 2004 at the Research Center of China AgriculturalUniversity to examine the effect of PGR SHK -6 (80%Diethyl aminoethyl hexanoate and Mepiquat chlo-ride , its ratio is 1∶5 on yield and quality of Soybean (Glycine max L .), cv .Kennong 5.SHK-6 was fo-liar applied in V 3 , R 1 , R 3 and R 5 stage at 100 mg ·L -1, with water as control .The results showed:1)SHK-6 treatment increased the number of pods and seeds per plant and the weight of seeds per plant , andsignificantly increased 8 .1%to 9.3%seed yield than control;2 SHK -6 treatments decreased the heights,and promoted the accumulation of biomass ;3 SHK -6 significantly increased the leaf physiology , such asphotosynthetic rate , chlorophyll content , the photochemistry efficiency were increased by SHK -6, andthe activities of RuBPcase , PEPCase and SPS were improved;4 The R 1 stage was the optimal time to spra-ying SHK -6 on soybean.
