甜荞不同品种不同海拔地区种子蛋白组分含量研究
Analysis of protein components in different cultivars of common buckwheat planted in different altitude areas
摘要
Abstract
In order to reveal the change laws of seed protein components among different varieties and among different regions, we studied seed protein components (albumin, globulin, prolamin and glutelin) of ten buckwheat species cultivated in four altitude areas.The results showed that the protein component contents in all the buckwheat cultivars were albumin > glutelin > globulin > prolamin.Among four different altitude areas, the highest protein component content of buckwheat seeds in average was 4.750% of albumin in Qinghai (alt.2 620 m) 1.081% of globulin in Inner Mongolia with the lowest altitude, 0.393% of prolamin in Shigatse, Tibet, and 2.805% of glutelin in Zhangjiakou, Hebei, respectively.Moreover, on a statistical average, the variety Meng 0530 had the highest albumin and glutenin contents, Chitianqiao 1 had the highest globulin content and Dingtianqiao 2 had the highest prolamin content.The variance analysis with two factors showed that there were highly significant differences of albumin contents among the different buckwheat varieties, and significant differences of prolamin contents among the different planted sites, and that both of the varieties and planted areas had significant effects on the contents of globulin and glutelin.And the correlation analysis showed that there were significant correlations of altitude with the prolamin content in Chitianqiao 1, and significant negative correlation with the globulin content in Meng 0530, but other protein component contents did not show any significant correlation with altitude.The above results are helpful to guide the common buckwheat breeding and cultivation and extension.关键词
