1 目前我国种子纯度鉴定的方法及利与弊目的我国常用种子纯度鉴定方法有:形态鉴定法(包括子粒与幼苗形态鉴定)、蛋白质电泳鉴定法、田间种植鉴定法。形态鉴定法:根据子粒与幼苗的形态特征进行鉴别的方法,该方法简单、快速、经济,但由于子粒与幼苗可辨性状较少,结果准确性差;蛋白质电泳鉴定法:随着科学技术的发展,蛋白质电泳鉴定法广泛应用于实验室检测纯度,该方法准确、时间短,是杂交玉米、杂交水稻、杂交番茄、小麦等作物用以室内电泳鉴定的主要方法,但对其他作物品种或某一作物的其他品种不太适宜;田间种植鉴定法:是鉴定品种纯度最为可靠、最为准确的方法,但是所需周
At present, the method of seed purity identification in our country and its advantages and disadvantages of the purpose of purity identification methods commonly used in our country are: morphological identification method (including the identification of seed and seedling morphology), protein electrophoresis, field planting identification method. Morphological identification method: According to the morphological characteristics of seedlings and seedlings identification method, the method is simple, fast and economical, but due to fewer identifiable seeds and seedlings, the results of poor accuracy; protein electrophoresis identification method: With the development of science and technology The method of protein electrophoresis identification is widely used in the laboratory to test the purity. The method is accurate and short in time. It is the main method for indoor electrophoresis identification of hybrid maize, hybrid rice, hybrid tomato and wheat. However, Other varieties of crops are not suitable; field cultivation identification method: identification of species purity is the most reliable and accurate method, but the required weeks
