Abstract:
A soybean(Glycine max)cultivar,Kennong 4 with seed soaking treatments by different concentration of plant growth regulator Diethyl aminoethyl hexanoate(DTA-6)and Uniconazole(S-3307)were employed to compare root activity,content of soluable sugar,soluable protein and nitrate in early stage of root formation.The results showed that,compared with CK,50 mg.L-1 DTA-6 and 0.4 mg.L-1S3307treatment increased the root soluble sugar and nitrate content,effectively increased root activity in early stage of root formation;while 50 mg.L-1 DTA-6 and 0.1 mg.L-1S3307treatment effectively increased root activity in later stage of root formation;25 mg.L-1 DTA6 and 0.4 mg.L-1S3307treatment effectively increased root soluable protein content in later stage of root formation.The results above indicated that 50 mg.L-1 DTA-6 and 0.4 mg.L-1S3307seed soaking treatment is effective to increase root activity and assimilate accumulation in root formation of soybean.
