Abstract

|
|
|
The changes in protein fractions and its gel electrophoretic pattern of rapeseeds (Braya napus) were investigated during germination at 25℃ under dark condition. The major protein fraction was found to be albumin 25.0%) and globulin (24.6%). Both fractions were decreased throughout germination, particularly significant for albumitt, whileprolamine(22%) and glutelin (1.8%) showed an initial decrease followed by a slow increase at the later stage of germination. The initial 5-6 peaks of gel electrophoresis were reduced to a few after 45 hours. The absorption spectrum at the range of 400-700 nm showed a significant increase in absorbance for sodium hexametaphosphate (SHMP) extract of rapeseeds. The protein extractability with SHMP was not significantly affected by germination.
