鉴定玉米种子纯度普遍采用的电泳方法有两种 :一是酯酶同工酶电泳 ,二是蛋白质电泳。 1 992～ 1 999年 ,结合田间小区种植鉴定 ,研究了应用酯酶同工酶鉴定玉米种子纯度的可靠性。结果表明 ,这种鉴定方法是非常有效的。实际鉴定中可多种方法结合运用 ,达到鉴定的准确性。 Identification of maize seed purity commonly used electrophoresis methods are two: First, esterase isoenzyme electrophoresis, the second is protein electrophoresis. From 1992 to 1999, the reliability of identification of maize seed purity by esterase isozyme was studied with the identification of field planting. The results show that this method of identification is very effective. The actual identification can be combined with a variety of methods used to achieve the accuracy of identification.
