采用聚丙烯酰胺薄层凝胶电泳法分析酯酶同工酶表明:大豆模式酶带共十条,分为两个区段,下位带共六条(包括两条共性带),上位带共四条.从野生大豆到栽培大豆,带幅由狭变宽,带包由浅变深,种间带位和带条数目也有差异。野生大豆带型的递变与性状递变相吻合,说明带型与生态型有一定的联系。有带比无带,多带比少带、显带比隐带、宽带比狭带在数量性状的表现程度上作用大,而且带位越低,带条越宽,带色越深,作用越大,尤其是高位带条。 Analysis of esterase isoenzyme by polyacrylamide gel electrophoresis showed that there were ten bands in soybean pattern, divided into two segments, six bands in the lower band (including two common bands) and four bands in the upper band. Wild soybeans to cultivated soybean, breadth by narrowing wide, with the package from shallow to deep, interspecies bands and the number of bands are also different. The variation of wild soybean pattern coincided with the gradual change of characters, which indicated that there was a certain relationship between belt pattern and ecological pattern. There are bands with no band, with more than a few bands, band than the hidden band, band than the narrow band in the quantitative performance of the role of a large extent, and the lower the band, the wider the band, the darker the ribbon, the role of more Large, especially high ribbon.
