초록
야생대두(野生大豆)(Glycine ussuriensis, 13개(個) 국내수집종(國內蒐集種)) 종실단백질(種實蛋白質)의 acylamide gel 전기영동양상(電氣永動樣相)을 Glysin gracilis 및 광교(光敎)(G. max)와 비교(比較)하였다. 야생대두(野生大豆)의 단백질함량(蛋白質含量)은 평균(平均) 50%로 gracilis (46%)나 광교(光敎)(45%)보다 높았으며 종실중(種實重)(2.1g/100립(粒))은 gracilis의 1/3, 광교(光敎)의 1/9이었다. 전기영동(電氣泳動)된 단백대(蛋白帶)는 야생대두(野生大豆)에서 총(總)16개(個)였으며 이중 3개(個)(
Acrylamide gel electrophoretic pattern of 13 wild soybean (Glycine ussuriensis) was compared with that of G. gracilis and G. max var. Gwanggyo. Average Protein content (50%) of wild soybean was greater than that of C. gracilis (46%) and Gwanggyo (45%). Grain weight of wild soybean was one third of G. gracilis and one ninth of Gwanggyo. Electrophoresis of wild soybean protein showed total 16 different bands and three of which (Rm 0.09, 0.59 and 0.84) were specific and did not appeared in 86 var. of G. max which showed four specific bands (Rm 0.35, 0.45, 0.50 and 0.77) of total 17 bands. G. glacilis had all bands of Gwanggyo and two bands (Rm 0.53 and 0.59), one of which (Rm 0.59) was specific for wild soybean indicating that G. gracilis is middle type. Of 16 protein bands the third band (32%), the first band (28%) and the 5th band (13%) were main bands. Electrophoretic pattern could be sorted qualitatively into 4 groups, semiquantitatively into 6 groups and 2 or 4 groups depending on reference pattern by correlation or pattern similarity method. All sorting methods separated a wild soybean from Sogri mountain into a group and except that there were no similarity among methods but correlation methods seems more reasonable. Protein content was no relation with electrophoretic pattern but positively correlated with percent contribution of first band at 5% level suggesting that the first band may have a important role for protein synthesis.
