Abstract:
Phosphorous plays an important part in the formation of glutenin subunits.The objective of the study was to investigate the effect of phosphorus on accumulation and content of glutenin 7S and 11S in different soybean varieties.Three widely distributed soybean genotypes in Heilongjiang Province，namely Dongnong 42(high-protein)，Dongnong 46(high-oil) and Hefeng 25(mid-type ) were used.The soybeans were planted in pots and fertilized with 0.033 g N kg-1soil and 0.033 g K2O kg-1soil.Four levels of phosphorous treatments，0，0.033，0.067，0.100 g P2O5kg-1 soil (denote as P1，P2，P3 and P4)were designed.The glutenin subunits，7S and 11S were extracted and analyzed by SDS-PAGE.The results showed that the contents of 7S and 11S subunits gradually increased，reached the peak values at 70 days after flowering and decreased at maturity.Each subunit content in 7S and 11S fractions as well as the glutenin contents reached their highest value under P3 treatment for Dongnong 42 and Hefeng 25;Under the same P treatment，the highest value of subunits contents of 7S and 11S and glutenin appeared in Dongnong 42，the lowest was in Dongnong 46.The results suggested that phosphorous treatment has an effect on the content of 7S and 11S as well as different subunits，and appropriate phosphorous treatment is beneficial to improve glutenin and subunits contents.
