采用蛋白质凝胶电泳与田间种植鉴定两种方法鉴定了２５个玉米种子样品的纯度。表明两 者结果显著相关，相关系数 ｒ＝０． ５８３，确定了回归方程为： ｙ＝０． ５６４＋０． ４２７ ｘ。证明蛋白质凝胶 电泳法鉴定玉米种子纯度是可靠的．表１，参２。
The purity of 25 maize seed samples was identified by two methods: protein gel electrophoresis and field planting identification. The results show that the two are significantly related, the correlation coefficient r = 0. 583, determine the regression equation is: y = 0. 564 + 0. 427 x. It is proved that it is reliable to identify the purity of corn seed by protein gel electrophoresis. Table 1, reference 2.
